8. A. nana^ Engl, in Engl. Jahrb. xxvi. 423. Rhizome creeping, 

 internodes short. Leaves small ; petiole 1^-1 f in. long, sheathing to 

 the middle or beyond ; blade about 2J in. long, 1 J-1 J in. broad, ovate- 

 lanceolate, acute, cordate at the base ; veins numerous, curved, ascend- 

 ing. Peduncle 'i-'i\ in. long. Spathe J-1 in. long, lanceolate, acumi- 

 nate, slightly convolute, pale green. Spadix longer than the spathe, 

 cylindric ; female part 3J lin. long ; male part 7 lin. long. Ovary 

 depressed-globose. — Notizbl. K. Bot. Gart. Berl. ii. 281. 



Upper Guinea. Cameroons: Victoria, Lehmhach. 



I have not seen this species, but, judging from the description, I think it is 

 probably a small state of the variable A. JBarteri, Schott. 



17. CAIiLOPSIS, Engl, in Notizbl. K. Bot. Gart. Berl. i. 27, 



Spathe expanded to the base, persistent. Spadix monoecious, shorter 

 than the spathe, covered with unisexual flowers, without an appendix 

 or neuter organs ; female part adnate throughout to the spathe, uni- 

 lateral ; male part free, a short distance from the female part, cylindric. 

 Perianth none. Female flowers few, laxly subbiseriate ; ovary 1 -celled; 

 style short, conoid ; stigma small ; ovule solitary, basal, anatropous ; 

 staminodes none. Anthers of male flowers sessile or subsessile, crowded 

 into a cylindric spike, subquadrate, 2-celled ; cells opposite, subovoid, 

 •opening at the apex by a confluent oval pore. — A herb with a creeping 

 rhizome, and petiolate entire cordate leaves. Peduncle as long as the 

 petioles. 



An endemic monotypic genus. 



Engler places this genus in the tribe Pothoidece, but in my opinion it should be 

 placed in the tribe ZomicarpecB, and stand next to Zomicarpella, from which it 

 differs chiefly in habit and in having no .appendix to the spadix, nnd is certainly more 

 nearly allied to that genus than any other known to me. The two other genera 

 belonging to the ZomicarpecB arc natives of Tropical America, and Callopsis is 

 therefore interesting as forming another connecting link between the African and 

 American Floras.
