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, N. E. 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, 3J-4 in. broad, 

 oblong or elliptic-oblong somewhat cuspidate-acuminate, na-rrowed 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 

 undula.ted, frill-like, very obtusely rounded at the apex, dark purple. 

 Spadix much longer than the spathe ; flowering part cylindric, about 

 7 Hn. thick, female 9-10 lin. long, male about 1 in. long ; appendix 

 (imperfect) over a foot long, about j 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 

 Amorphopliallus, except the gigantic A. Titanum, Becc, which they rival in size. 



28. A. Zenker!, N. E. 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 J in. long, 

 2J-2J in. broad, the others smaller, all oblong-lanceolate, long 

 acuminate, very acute, decurrent at the base. Peduncle f-1 J 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, J in. thick, cylindric ; 

 male part | in. long, | in. thick; appendix about 14 in. long, ^ in. 

 thick, irregularly sulcate. Ovary shortly ovoid ; stigma sessile,

Unknown to me. It was described from a plant cultivated in the Hotanic 

 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 A. Barteri, N. E. Br.
