Trochomeria.] lxiv. cucurbitace2E (hooker). 525 



? Form 3. Leaves as in form 1, but lobes lanceolate, sometimes with orbicular pecti- 

 nate stipular bracts at the base. 



? Form 4. Leaves broadly reni form-cord ate, acuminate, obscurely lobed or angled, 

 irregularly and obtusely toothed, peduncles solitary or in pairs, 1-tiowered. 



Mozamb. Distr. Form 2. Open country N. of Chiradzura, Lat. 14°-19° S. 

 Dr. Kirk! 



Lower Guinea. Forms 3 and 4. Angola, Pungo Andongo, dry woods and bushy 

 places, Dr. Welwitsch! 



2. T. vitifolia, Hook.f. Stems almost glabrous, climbing amongst 

 grass. Leaves very variable, sometimes reduced or absent, triangular- 

 cordate, acute, with a broad basal sinus, 3-5-lobed or -angled, coarsely 

 unequally toothed, all but glabrous above, minutely pubescent with 

 scattered hairs below, not scabrid, membranous. Stipular bracts broadly 

 ovate-cordate, deeply ciliate-toothed. Male fl. : On capillary 1« 

 flowered peduncles 2-2J in. long. Calyx-tube J in. long, \ in. diameter, 

 cylindric. Corolla-lobes as long as the calyx-tube, subulate-lanceolate. 

 Female fl. : Shortly peduncled, calyx and corolla as in the male. 

 Ovary slightly pubescent. 



Lower Guinea. Angola, Golungo Alto, alt. 1000-2400 ft., amongst grasses and 

 shrubs on stony hills, Dr. Welwitsch! 



Root very large, eaten by the negroes, and used as a medicine. The leaves in the 

 best developed specimens are triangular-cordate, with a large shallow sinus at the base. 



3. T. macroura, Hook. f. Stem glabrous or slightly scabrid. 

 Leaves very variable, oblong- hastate, entire with the basal lobes more 

 or less spreading or digitately 5-lobed to near the base, margins irregu- 

 larly rather obtusely toothed ; lobes linear or lanceolate or oblong, 

 slightly scabrid on both surfaces, upper without white papillae, lower 

 with minute black papilla? ; petioles short. Male fl. : Peduncles very 

 long, capillary, 2-3 flowered, with the capillary pedicels 5—7 in. 

 long. Calyx- tube very slender, funnel-shaped, 1^- in. long; lobes as 

 long, subuiate or almost filiform. Anthers hairy at the tips. Female 

 fl. : not seen. 



Upper Guinea. Open country, Nupe on the Niger, Barter! 



There is another species, apparently of this genus, collected by Baines in South 

 Central Africa, which in its much divided leaves, covered above with large white 

 papillae, resembles the South African T. debilis (Zekneria, Sond.), but the fruit is very 

 much larger and oblong, the seeds are as large as those of T. macrocarpa, from which 

 its papillose leaves distinguish it. 



lu Dr. Welwitsch' s collections there is perhaps a fourth species, differing from T. ma- 

 crocarpa in being almost glabrous, and having larger and more membranous leaves 

 3-lobed to near the base, the middle lobe oblong lanceolate, the latter falcately curved 

 upwards and cut into two broad obliquely obovate obtuse lobules : it may be a form of 

 T. vitifolia. 



3. HETEROSICYOS, Welwitsch ; Benth. et Hook. f. 

 Gen. Plant, i. 822. 



Flowers of Trochomeria, but erect pubescent herbs, without tendrils. 



Probably better regarded as a section of Trochomeria, remarkable for its habit and 

 the absence of tendrils. 



Leaves polymorphous. Flowers brown-purple 1. H. polymorpha. 



Leaves all 3-partite with linear segments. Flowers straw-yellow . 2. H. stenoloba.
