OF THE MATTO GROSSO EXPEDITION, 1891-92. 325 
A small specimen in the Herbarium at Kew, collected by Blanchet (no. 3628), is 
perhaps to be referred to this variety, though its thicker leaves are stellately pubescent on 
their underside, not tomentose. [Bras. Or. |

Species forsitan juxta H. confertifloram, A. Juss., ponenda, sed multis notis dispar. 
The Cuyabá specimens are in flower, those from Santa Cruz in the fruiting stage, and 
except for the former having somewhat larger leaves, less rusty beneath, I can see no 
difference between them. [Bras. Or.] 
Verisimiliter in hoc genus digerenda et juxta speciem precedentem interponenda exstat 
planta fruticosa metralis quam ad Santa Cruz legi (n. 336), caule erecto, tereti, superne
