and Pseudhydrosme gabunensis, Engl., are such, that they ought not, in my 
opinion, to be placed in the same genus, I have, therefore, generically separated 
them, Eugler states that the spathe of the specimen of Z, Buttneri, according to 
the collector’s notes, has about 2 ft. of the upper part wanting ; it is, therefore, only 
very shortly convolute at the base, and not nearly to the obliquely truncate top as 
in Pseudhydrosme ; the anthers of Zyganthera are connate in pairs, the upper half 
of the spadix is covered with barren organs, and the ovules are short and broad, whilst 
in Pseudhydrosme the anthers are free, different in character, the spadix has no barren 
organs, and the ovules are long and narrow. 
6. PSEUDHYDROSME, Engl. Jahrb. xv. 455. 
Spathe funnel-shaped, convolute to the obliquely truncate top. 
Spadix free, monecious, fertile to the apex; male and female parts 
contiguous; appendix none; staminodes or neuter organs none. 
Perianth none. Ovary 2-celled; style short; stigma slightly bilobed. 
Ovules solitary in each cell, affixed near the base of the axile placenta 
‘on very short funicles, erect, anatropous. Anthers free, compressed, 
2-celled ; connective rather broad, produced beyond the cells into a 
transverse sub-bilobed knob; cells linear, opposite.—A tuberous 
rooted herb, flowering before the leaves appear. Leaves unknown. 
Peduncle very short. 
An endemic monotypic genus, 
1. P. gabunensis, Lngl. Jahrb. xv. 455, tt. 15-16. Leaf un- 
known; peduncle about 1? in. long, enclosed by several cataphyllary 
leaves, the longest of which are about 3-3? in. long. Spathe 12-16 
in. long, and about 8 in. diam. across the top, funnel-shaped, obliquely 
truncate, slightly undulated at the margin. Spadix 3} in. long, about 
lin. thick, cylindric, obtuse, densely covered with unisexual flowers ; 
female part about 1} in. long; male part contiguous to the female, 
densely covered with fertile anthers to the apex. Ovary oblong-ovoid, 
narrowed into a short thick style; stigma bilobed, not thicker than 
the style. Anthers free, subsessile, linear-oblong ; connective produced 
into a transverse thickened minutely papillate knob.—Engl. & Prantl,
