Frutex erectus, sparse pabescens, usque ad 8 ped. altus. Oaulis validus. 
Folia 8-18-juga, rhachi satis valida; foliola elliptica vel’ obovata,

racteolati. Calycis dentes setaceo-acuminati, tubo paullo breviores, 
postici deltoidei, laterales semilanceolati, anticus anguste triangularis. 
Corolla rubro-purpurea ; vexillum ovato-orbiculare, emarginatum, infra 
medium reflexum, carinam leviter curvatam obtusam paullo superans ;

curvato. Ovarium longiuscule stipitatum, sericeo-pubescens; stylus 
pilorum fasciculo terminali carens. Legumen breviter stipitatum, sutura

coronatum ; semina rugosa, 
The small tribe Colutee contains seven or eight rather 
closely allied genera, three of which, Lessertia, Sphero- 
physa, and Swainsona might well be united. Spherophysa 
scarcely differs from Swainsona except in the more globose 
pod, and Taubert has accordingly reduced it to the latter 
genus. The separation of the S. African Lessertia from 
Swainsona, which includes about forty Australian species, 
and one from N. Zealand, is hardly more justifiable. 
Swainsona has a more or less two-celled pod by intrusion 
of the ventral suture, and the style usually bearded along 
the inner side; Lessertia a one-celled pod, and a style 
which usually is not bearded along the inner side; but 
Swainsona lava has the style of a Lessertia, and Lessertia 
physodes that of a Swainsona. | 
Taubert, though keeping the two genera distinct, admits 
that they will probably be united by some future mono- 
grapher.
