maximus, then A. Fischeri is doubtless distinct from it, but if it is smooth there 
seems to be no character of sufficient importance to distinguish them specifically. 
27. A. Mannii, V. #. Br. Leaf very large, probably 4-5 ft. 
diam.; petiole in the dried state densely sulcate-striate, probably 
smooth when alive ; terminal segments 7-12 in. long, 34-4 in. broad, 
oblong or elliptic-oblong somewhat cuspidate-acuminate, narrowed and 
decurrent at the base. Peduncle furrowed like the petiole. Spathe 6-7 in. 
long, obliquely campanulate, convolute at the base ; tube densely covered 
inside with curved hair-like processes, dark purple ; limb or border much 
undulated, frill-like, very obtusely rounded at the apex, dark purple. 
Spadix much longer than the spathe; flowering part cylindric, about 
7 lin. thick, female 9-10 lin. long, male about 1 in. long; appendix 
(imperfect) over a foot long, about } in. thick at the base, gradually 
tapering to the apex, smooth, dark coloured in the dried state. Ovaries 
moderately crowded, globose, 2-celled ; stigma sessile, discoid. Anthers 
densely crowded.

The peduncle of the only specimen seen is very much compressed, and about 2 in. 
long, but has been broken off, so that it is impossible to say how long it may have 
been. The leaf-segments of this plant are larger than those of any other species of 
Amorphophallus, except the gigantic A, Titanum, Becc., which they rival in size, 
28. A. Zenkeri, V./. Br. Leaf solitary ; petiole 20—24 in. long, 
its three primary branches divided into two pinnatipartite divisions 
bearing 4 (often opposite) segments; terminal segments 5-5} in. long, 
24-23 in. broad, the others smaller, all oblong-lanceolate, long 
acuminate, very acute, decurrent at the base. Peduncle ?—1} in. long. 
Spathe about 8 in. long, and 4 in. diam., convolute, broadly campanulate, 
undulated at the purple margin; lower part of the tube clothed inside 
with filiform processes, blackish-purple. Spadix about twice as long 
as the spathe; female part about 7 lin. long, } in. thick, cylindric ; 
male part } in. long, 2 in. thick; appendix about 14 in. long, # in. 
thick, irregularly sulcate. Ovary shortly ovoid; stigma sessile, 
orbicular—Hydrosme Zenkeri, Engl. Jahrb. xxvi. 421.

This species, of which I have not seen a specimen, seems to be allied to 4. Mannii,

Unknown to me. It was described from a plant cultivated in the Botanic 
Garden at Paris, and on account of its lanceolate, acuminate leaflets, and different 
locality cannot be the plant described as Hydrosme Fontanesii by Schott and Engler, 
for which see 4, Barteri, N. E. Br.
