12. H. macrophylla, VaJd ; DC. Prod. i. 56S. A glabrous shrub. 

 Leaves rather large, more or less coriaceous, broadly elliptical, shortly and 

 acutely apiculnte, more or less broadly rounded at the base, obscurely un- 

 dulate-crenate or subentire, glabrous, principal lateral veins prominent be- 

 neath, 5-9 in. long, 25-4| in. broad ; petiole ^-f ' in. Cymes very laxly 

 forking, 5-6 in. long, with straight rather slender internodes. Flowers 

 large; pedicel of central flower of each fork \-^ in. Calyx-lobes broadly 

 rotundate. Petals 3-5 lines long, thin, broadly obovate, with the sides 

 much incurved at flowering. Disk broad with a free margin clothing the 

 base of the calyx. Anthers broadly transverse-oblong. Ovary half-im- 

 niersed. Fruit not known. — //. rotuyidifoUa , Hook. f. Fl. Nigrit. 279.

This plant appears very nearly allied to a tropical American species {Cuerca, Triana's 

 mss. ; Hippocratea malpic/hifolia, Rudge ; DC. Prod. i. 5G8j, but in the absence of fruit 

 I cannot safely identify them. 



13. H. graciliflora, Welw. mss. An extensive climber, wholly gla- 

 brous. Leaves membranous, turning black on drying, elliptical to oblong- 

 elliptical, subacutely or rather obtusely acuminate, cuneate at base, serrulate, 

 2-4 in. long, 1-ly i"- broad; petiole i-| in. Flowers greenish, in lax, 

 widely-divaricating, slender, axillary cymes, equalling or but little shorter 

 than the leaves; pedicels ^ in. more or less. Bracteoles very minute, tri- 

 angular-subulate. Sepals half-orbicular. Petals spreading, rotundate, ob- 

 soLetely unguiculate. Anthers much elongated transversely, forming an ap- 

 parently sessile triangular enclosure around the obtuse subsessile stigma. 

 Filaments very short and much dilated, closely investing the ovary. Ovules 

 apparently about 6 in each cell. Fruit unknown.

 times panicled towards the ends of the branches, singly subsessile or pedicels 

 equalling the flowers. Sepals roundish-ovate. Pt-tals broadly oblong or 

 orbicular. " ciliolate," imbricate in aestivation. " Anthers depresscd-rotun-

I have not seen an authentic specimen of thie plant. Were it not that the a\% of 

 Barter's plant are dabrous, I should not have hesitated to identify it vi\{\\ 11. paniculata, hi 

 described in the ' Flora Senegambia^.'
