crenate, deltoid and entire at the base, thick and rigid in texture,

shortly-peduncled spikes 2-3 in. long from the axils of the upper 
leaves. Ovary pentagonal, cuneate, sessile, 4 line long, with 5 
small obtuse segments. Petals 5, rarely 6,4 line long. : Stamens 
5, opposite the petals, not more than 4 as long. Styles 3, erect, 
as long as the filaments.—Forest of Andrangaloaka, Dr. Parker! 
Forests of Imerina province, Baron 1295! Allied to H. africa- 
num, Benth., and H. longistylum, Masters. H. tetramerum, 
Baker, in Trimen's Journ. 1882, p. 110, has been refound by 
Mr. Baron (No. 858); and in his fine set of specimens there 
are occasionally pentamerous and even hexamerous flowers. 
PHARNACEUM SUFFRUTICOSUM, n. sp. 
Suffruticosum, glabrum, stipulis scariosis deltoideo-cuspidatis haud 
laceratis, foliis sessilibus fascieulatis subulatis muticis, peduneulis strictis: 
axillaribus erectis elongatis 1—3-floris, sepalis 5 obovatis obtusis, stami- 
nibus 10 calyce brevioribus, fructu ovoideo oblongo 5-loculari calyci 
s&equilongo. 
A much-branched shrubby perennial, glabrous in all its parts,

Corolla none. Stamens 10, rather shorter than the sepals, with

as the calyx, splitting down to the base into 5 loculicidal valves, 
each cell containing a few small brown cuneate seeds.— Province
