Vexillum pilosum brevius quam 25 cm. longum. 

 Foliola ovata. 



Foliola supra velutina, subtus moUiter hirsuta micans Taub. 



Foliola subglabra versicolor Welw. 



Foliola oblonga caffra Meissn. 



Vexillum tenuiter sericeum, 30-35 mm. longum 



Sacleuxii Dunn, sp. n. 



Millettia Stulilmanni Taub. and M. Laurentii De Wild., with 

 glabrous corollas, also belong to this section. 



As Dr. Harms recently pointed out to the writer, the different 

 forms which have usually t)een referred to M. ferruginea Baker 

 and to M. leucantJia YB,tke, respectively, require revision, and after 

 a careful study of the fine series sent back by German collectors 

 from German East Africa, and by British collectors from Uganda, 

 it appears convenient to recognize a small group of shrubby 

 species related to them in the following manner : — 



Frutices erecti ; foliola multijuga, stipellata ; vexillum sericeum. 



Pedicelli calyce vix longiores ferruginea Baker. 



Pedicelli calyce multo longiores. 

 Flores calyce 2-3 -plo longiores. 



Vexillum oblatum, carina valde falcata oblata Dunn,sp.n. 



Vexillum ovatum, carina haud falcata... dura Dunn, sp. n. 



Flores calyce 4-5-plo longiores ... leptocarpa Dunn, sp. n. 



Frutices erecti ; foliola paucijuga, stipellata ; vexillum pilosum. 

 Paniculi rachis calyxque breviter adpresse sericei 



lasiantha Dunn, sp. n. 

 Paniculi rachis calyxque dense velutini leucantha Vatke. 



The group of West African climbers, of which M. Barteri 

 (Benth. suh Lonchocarpus) is the best known example, may be 

 arranged as follows: — 

 Foliolorum venae impressse. 



Bracteas longse lineares ; foliola 4 (-3)-juga, hirsuta ; 

 stipellse nuUae vel minutae. 



Foliola subtus molliter ferruginea Soyauxii Taub. 



Foliola subtus tenuiter hirsuta bicolor Dunn, sp. n. 



Foliola subtus adpresse sericea 



Gagnepaineana Dunn, sp. n. 

 Bracteae breves ; foliola 3-paria, subglabra. 

 Foliola stipellata. 



Flores 15 mm. longi ; foliola obtusa Goetziana Harms. 

 Flores 10 mm. longi ; foliola acuminata impressa Harms. 



Foliola exstipellata calabarica Dunn, sp. n. 



Foliolorum venae haud impressae Barteri Dunn, nom. n.''' 



• Millettia urophylla Welw. cannot be distinguished" from Lonchocarpus 

 Barteri Benth., which has priority of pubUcation.
