I n h i s key to the genera i n "North American F l o r a " ( V o l . x x i v , No. 5,) Dr. Rydberg separates h i s new genus Gynophoraria i n t o the group "Keel without a d i s t i n c t beak", y et i n h i s diagnosis of the genus he admits "Wings and k e e l p e t a l s unknown"I(p. 280) While the above instances c e r t a i n l y oreate enough d i f f i c u l t y w i t h i n the genus, probably most of the e x i s t i n g confusion has been caused by the " s p l i t t e r s " . The, .genus. .Astragalus,. -which seems. to. f a l l , i n t o a n a t u r a l group has been.variously treated, by d i f f e r e n t , authors.. Some have .been.content, t o leave the group as a genus, d i v i d i n g i t i n t o sections and subsections i n order t o .show, the r e l a t i o n s h i p s of i n d i v i d u a l - s p e c i e s . Others have subdivided the. original.genus i n t o separate genera, and t h i s p r a c t i c e reached, i t s . z e n i t h w i t h the treatment by the. late.Dr.. Rydberg i n the "North..American F l o r a " , where twenty seven genera emerge from what was formerly.... one.. This might be acceptable, i f . the new. genera were separable by any group of constant c h a r a c t e r s , but unfo r t u n a t e l y the characters which Dr. Rydberg b a s i s h i s . separations are very a r t i f i c i a l . Some, of h i s generic separations, are.at,most only s u f f i c i e n t to d i s t i n g u i s h between, species., and some of h i s .s p e c i f i c , separations would..appear to distinguish.between, mere forms.. For example.; Rydberg ..separates, h i s , genus.Braohyphragma w i t h . " p o d . d i s t i n c t l y s t i p i t a t e " from Gontortuplioata,.. Hamosa, and Hedophylla with, "pod sessile., or n e a r l y so". There.is a margin of doubt as to. when.a.pod i s " d i s t i n c t l y s t i p i t a t e " , and when i t i s "nearly sessile." Could i t not be d i s t i n c t l y s t i p i t a t e , but ne a r l y s e s s i l e ? Again, i n h i s treatment of Xylophac.os. (p. 290 North American,.Flora) he separates S e c t i o n B r i o c a r p i (with .five species) from S e c t i o n G l a r e o s i (sixte.en..sp.ecies.) by "pubescence o f leaves, s t r i c t l y appressed" and "pubescence of leaves l o o s e l y v i l l o u s " . These.major, separations are based on points, t h a t would only be used w i t h h e s i t a t i o n , f o r s p e c i f i c , separation, by the author. . The a r t i f i c i a l i t y of Dr... Rydberg's. c l a s s i f i c a t i o n m a y be i l l u s t r a t e d by a. .comparison, of h i s treatment of. Astragalus, alpinus., L.. I n h i s "Flora, of. the.Rocky..Mountains, adjacent P l a i n s " (19.17) Rydberg separates the. genus. .Tium...from. Ate io.phragma . and. Linnaeus • species appears as . Tium alpinum(L) Rydb. However i n the North American F l o r a (1929) the same p l a n t i s c l a s s i f i e d as... At elophragma.. al p inum.

THE RECTIFICATION OF. THE CAUSES OF CONFUSION.. The.. confusion...arising. from, the .use. of incomplete. " F l o r a s " has been eli m i n a t e d by the., inclusion... of a l l species recorded...for B r i t i s h Columbia. This l i s t has been taken from the f i l e s of the P r o v i n c i a l . .Herbarium at. the U n i v e r s i t y of B r i t i s h Columbia. I t .includes.the names of a l l species which have been.recorded..for. the .province, together, with..a l i s t of p u b l i c a t i o n s containing.a description..or illus.tr.ation...of. the species.. The cure f o r erronous determination i s the checking of the m a t e r i a l w i t h the o r i g i n a l , descriptions.. These o r i g i n a l d e s c r i p t i o n s of the As t r a g a l i . , were... i n most, cases taken, verbatim... f ram. the o r i g i n a l , work., punotuation. and. even..typographical .errors being c a r e f u l l y t r a n s c r i b e d . This. was .done., since, many, .of our, recorded..species, come .under A r t i c l e . 1.8 of "The...International. Rules o f B o t a n i c a l Nomenclature" which s t a t e s i n part»_ " I n .some species*., however..,, the-, type... i s . a ..description, or f i g u r e given by.. a previous ..author.." (p. 3, 1935 ed.) The d e s c r i p t i o n s o f the species, i n the..various " F l o r a s " were checked w i t h the o r i g i n a l s , and any discrepancies ...noted. Species, that... were, o r i g i n a l l y , founded on incomplete. n a t e r i a l .had, n a t u r a l l y , incomplete descriptions.. These have been, augmented from other, f l o r a s , whose...des_criptions agreed i n every other, respect w i t h the o r i g i n a l . This .was f e l t to be probably the most s a t i s f a c t o r y method of f i l l i n g i n the m i s s i n g data,... since i t was impossible t o compare the o r i g i n a l specimens w i t h others which were more complete. -6-. The. e l i m i n a t i o n of the confusion caused by " s p l i t t i n g . " i s perhaps, themost debatable procedure undertaken. U s u a l l y the o r i g i n a l d e s c r i p t i o n s a r e i b r o a d enough t o permit of environmental v a r i a t i o n , but many of the o r i g i n a l - d e s c r i p t i o n s , of Dr. Rydberg a l l o w f o r l i t t l e or no v a r i a t i o n at a l l . Apparently he. f e l t t h a t any plants which could.be separated were worthy o f . s p e c i f i c rank, and.thus r a i s e d a l l v a r i e t i e s , and even forms to. the. status of species. The above procedure could have, been followed here had the ob j e c t i v e been the description... of new. "species". Such a d e f i n i t i o n , would then l i m i t the d i s t r i b u t i o n , of. c e r t a i n "species" t o the "type l o c a l i t y " , l e a v i n g no evidence as t o how t h a t ' p a r t i c u l a r , "species" evolved i n t h a t one p a r t i c u l a r region.,- or from what l i n e i t . a r o s e . . The o b j e c t i v e of t h i s r e v i s i o n i s not the d e s c r i p t i o n of new genera .. or species, but r a t h e r an attempt t o show the r e l a t i o n s h i p of those A s t r a g a l i - recorded f o r B r i t i s h Columbia./ The. o b j e c t i v e , includes the preparation,of a key which, w i l l , enable even the:layman t o d i s t i n g u i s h , between these species. The examination of many p l a n t s i n the f i e l d shows that, any species v a r i e s w i t h . i t s . h a b i t a t . These, v a r i a t i o n s , .may a l t e r the. appearance of the. p l a n t e n t i r e l y , such, as in... Astragalus. serotinus Gray. On the exposed. open, range., on. a. dry southern...slope., . t h i s p l a n t i s low, w i t h very narrow pubescent l e a f l e t s , and presents, a. s i l v e r y appearance. The same p l a n t , growing, w i t h Calamagrostis . rubescens.,. Buck!., under a cover of Pinus. c o n t o r t a , Dougl. i s t a l l , slender, w i t h broader, almost glabrous l e a f l e t s , presenting a. d e f i n i t e green appearance. On herbarium sheets, these two i n d i v i d u a l s are very r e a d i l y d i s t i n g u i s h a b l e , but the characters of separation are not constant., as can be, quickly;; seen i n . the, f i e l d . Thus, i n t h i s , treatment of the genus, the separation of species stops at t h a t point where the characters used are subject t o v a r i a t i o n . -7-' THE CHARACTERS USED IS SEPARATION. I t i s a recognized, f a c t i n botanical, ecology that the reproductive organs and c l o s e l y associated plant s t r u c t u r e s s u f f e r l e s s change from environment than.do.the vegetative parts of the plant. Owing t o the greater constancy of these, characters, the separations i n t h i s paper have been based on the f r u i t s and f l o r a l s t r u c t u r e s rather than on the f o l i a g e or even s t i p u l e s . While.separation on the b a s i s of f o l i a g e i s out of the question, separation on the. s t i p u l e s and t h e i r shape, cohesion and adhesion t o the p e t i o l e might be p o s s i b l e . I t i s f e l t however, t h a t such a key would not show the r e l a t i o n s h i p of the species as w e l l as a key based on more fundamental organs of the p l a n t . The key t o the s e c t i o n s and subsections i s based l a r g e l y on the work of Dr. A. Gray, w i t h the exception.that l i t t l e weight i s attached t o s t i p u l e characters, except f o r s p e c i f i c . c o n f i r m a t i o n . The reasons f o r r e j e c t i o n of the genus Phaca by Dr. Gray ( i n the Proc. Am. Acad. VI p. 189) a n d . i t s i n c l u s i o n i n Astragalus seems t o be quite w e l l supported by the B r i t i s h Columbia m a t e r i a l . Although there i s a gradual t r a n s i t i o n from the completely b i l o c u l a r . f r u i t s to these w i t h no s i g n of suture i n t r u s i o n , s t i l l i t was f e l t t h a t a l i n e could be drawn a r b i t r a r i l y t o separate the. former genera., as s e c t i o n s . Of the other, c h a r a c t e r s , the i n f l a t i o n , of the pod, and the length of i t s s t i p e are. p r e f e r r e d to the. texture., since, such terms as c a r t i l a g i n o u s , coriaceous., chartaceous and membranous, form a gradation w i t h room, f o r ambiguity. The flower c o l o u r , though f a i r l y constant, i s quite v a r i a b l e i n the amount of colour present. In purple t i p p e d species, the purple i n some specimens i s confined t o the t i p s of the p e t a l s * and i n others spreading back as f a r as the c a l y x . The colour of the calyx, pubescence.,, while of value i n . some, cases has been.quite overemphasized, by. Dr. Rydberg i n the "presence of black hairs.on. the c a l y x " . While t h i s feature may be constant, i n some species, in.others such. as. A. serotinus Gray i t i s quite v a r i a b l e , even i n f r e s h material.. The pubescence of the pods, while u s u a l l y more or l e s s constant, i s v a r i a b l e i n some species, e s p e c i a l l y those t h a t tend t o be t h i n l y pubescent, which may appear glabrous. Thus t h e s e p a r a t i o n s i n t h i s treatment are based only on s t r i k i n g d i f f e r e n c e s of pubescence. . THE..CLASSIFICATION. OF ..BRITISH. COLUMBIA..ASTRAGALI.
