Belgian Congo and Northern Rhodesia. On grassland and edges of thickets. A REVISION OF THE GENUS GLYCINE AND ITS IMMEDIATE ALLIES By F. J. HJ.;rnL\xx, senior' botanist. Crops Research Division, Agl'i cdtuntl Re8emd~ Sen'ice 1 INTRODUCTION The c1aim of the Old 'Yodd leguminous genus Glycine to economic ,importance rests very largely upon its inclusion of the soybean, Clycine matI.' (L.) )Ierr. A few others among the more common and widely ranging species, such as the principally Afriean G. jaz'anica L. and the Australian O. Canescen.s F.J.Herm. (0. 8el'icea Benth., not 'Yillel,), are of .alne as fodder, but their use does not compare in importance with that of G. ma;c, which is used so extensively for lUlman food and oil. AgTonomists attempting to impro,e strains in the world's soy bean crop ha'-e. heen interested in the wild species of Clycine as po tential material for interspecific crosses, but the literature on the sub:iect has been not only extremely ..ague fOl' the most part but fre quently clecicleclly misleading. A tabulation of the sl)(>cies described a:i OIY('ine fl'Ol11 Index Kewensis, for example, results in a total of :2H6 and the addition of published subspecies and ,"ariel ies In'ing-s the number to :~23, So loosely has the genus been defined, even in recent yea.rs, that the estimate of nLlid speeies within Ihe group by current tluthors has nlrieCl from "some 60" by H

It was found that genem already described ,yould accommodate the majority of the species that had to be excluded fl'ol11 Glycine, but for 11 of the excluded species :2 new genera had to be set up and are characterized in this paper, Because so large a proportion of the species ascribed to Olycine \\'ere proposed by early authors at a periocl \\-hen descriptions \\'ere habitually of snch bl'e\'it'), that the charaetel's del i ne::tted would apply to several or many eli fl'erent plants under our modem concepts, and because the pmetice of desi/!nnfing type speci mens, to establish beyond question the ielelll'ity of the plant descrihed, was not yet in vogue, it WflS nN'esSary 1"0 ::'eareh Ihe pl'in('ipal Eu ropean hedJar.ia, in an attempt to Jind t'he specimen npon whi('h ('nch descl'iption was based, In the majority of cases this se:tl'ch was ::'11(' cessful nnd the name \\'as satisfuctOl'ily cl isposed of. In a fC'\\' instanees the types are evidently lost and where the de::,cTiption is too fl'a/! mentary to offer a deci;:;i\-e clue to thei(LC'ntity of tIl(' plant inyol\'C'cl, the mune must still remain in doubt, although in no (,fl:';e cloes it seem likely £rom the evidence a\'ailable that it ean be appli('nble to n true Olycine, The ehier reason for the hetcl'ogelleow-i composition of the genus Ol!/cill(, as eal'liel' cl('finec1 is well lJl'ought om in the following ob sf'l'vntion by Benthilll1," made nearly a ('(·lItur)' ago:

Three of the species also have digitately trifoliolate lea,ves, a condition not found in the other subgenera. '1'he seeds are Ilslmlly of two types :within each species, very different in appeaL"ance, one smooth and often glossy, the other variously muriculate or papillose and foveolate. The latter condition is due to the true seed coat being covered by the dried, persistent remains of the peri sperm, which otherwise remains attached to the inner wall of the pod. As it partially disintegrates upon the seed-surface it shrivels in definite pattel'l1s usually forming tubercles or, in the case of O. tOlnentella, becoming foveolate as well as papillose.
