OF THE MATTO GROSSO EXPEDITION, 1891-92. 393 
Species Strychno nigricanti, Prog., arcte affinis, sed certe non conspecifica, a calyce 
fere usque ad basin divisá (nec vix usque ad medium), corollze lobis tubo duplo longi- 
oribus (nec ei zequilongis), staminibus exsertis, antheris ovatis, loculis basi divergentibus 
(nec oblongis, loculis basi parallelis), ovario subgloboso nec ovoideo differens. Flores 
insuper stirpis nostre albi, nec virides. 
Hujus inveni eodem loco mens. Nov. (n. 569) varietatem insequentem :— 
Var. SARMENTOSA, nob. Haud scandens, ramosissima, spinis orba (an semper ?). 
This variety is merely the mon-scandent form of the species. In this state the plant 
crows isolated, in the form of a shrub with exceedingly copious branching; but none of 
my specimens show either spines or tendrils, and moreover the internodes are shorter 
than is the case with the type. S. nigricans, Prog. I know only from the excellent 
figure and description in the volume of Martius. [Bras. Or. |
