Indo-Chiua, Turoiig (=Touraue), Kuntze 3781, Februaiy, 1875, 

 t.vpe of Ci-ypiophaseolus anamensis 0. Ktz., Britton Herbarium, New 

 York Botanical Garden. Kuntze 's genus and species were overlooked 

 by Gagnepain. From the de.scription one would searcel.y suspect that 

 CrypiophnseoUis is eongeneric with Canavalia, for the reason tliat 

 Kuntze 's type is a spécimen with very immature buds, the petals and 

 .stamens still ineluded in the very young calyces ; hence the misleading 

 name Cryptophaseolus. Gagnepain 's treatment of Canavalia is rather 

 luisatisfactory. He keyed four species, admitting three for Indo- 

 China. Of thèse, C. ensiforniis DC. is C. gladiata (Jacq.) DC, 

 C. tiirgida Grah. is C. microcarpa (DC.) Piper, and C. oMusifolia DC. 

 is C. iiuiritiina (Aubl.) Thouars — that is, if one wishes to use the oldest 

 valid naines for the recognized species. He does net admit C. virosa 

 Wight & Arn. A spécimen in the Kew Herbarium, Thorel 112, deter- 

 mined by Gagnepain as C. ensiforniis DC. apparently represents C. 

 virosa Wight & Arn. As interpreted by Dunn, C. virosa extends fr(nn 

 tropical Africa and the Mascarene Islands to India, Siam, and Yunnan.
