long, the narrow bracteoles immediately beneath the calyx 2 lines. 

 The calyx is 4 lines long, the subspreading segments 2 lines. The 

 corolla is 1^ in. long, and about 1 in. in vertical diameter at the 

 open mouth. The short tube is ^ in. long, the rounded-oblong 

 lobes 4-5 lines, the anterior one beins: smaller and shorter than 

 the others, of which the lateral are slightly the broader. The two 

 longer filaments are 10 lines long, the anterior slightly shorter. 

 The horizontally directed anthers are 3 lines long, they end in a 

 short point, and bear on the upper surface a longitudinal furrow 

 with a line of short hairs. The style is 1^ in, long. The smooth 

 dull brown capsule is 4^-5 lines long ; only one of the two valves 

 was present, so that it is impossible to say whether the fruit is 

 symmetrical or not. The seeds had all fallen. 



An interesting addition to the genus, which hitherto included 

 only the South African G. scahrn Benth, and the Socotran G.fniti- 

 cosa Balf . fil. In habit it approaches the latter, but is distinguished 

 from both its allies by its much larger, more open flowers. The 

 complete disappearance of the sterile half of the anther in the 

 posterior stamens is also of interest, 



Thunbergia longisepala, sp, nov. Volubilis, glabra, caule lig-

The terete light-colorired stem is less than 1^ lines in thickness. 

 The thin leaves on the younsr shoots are about f in, long, and as 

 broad ; the filiform petiole is slightly shorter ; the rounded apex is 

 often apiculate. The stout peduncle is 2-| in, long ; the large 

 bracts are f in. by scarcely i in. The calyx has a very short broad 

 cup ; the segments, which are narrow from a broader base, are ^ in. 

 long. The corolla-tube is nearly 1^ in. long and 1 line in diameter, 

 expanding to about twice the diameter 2 lines below the lobes, 

 which are 3-4 lines long. The filaments are ^ line long ; the two 

 smaller anthers 3 lines, the larger 3^ lines long ; a line of short 

 hairs indicates the line of longitudinal dehiscence, and the rounded 

 base bears a cluster of short spines. The filiform style is H lines 

 long. 



A very distinct species, recalling some forms of T. ajfxnis 

 S. Moore, from which, however, it is at once distinguished by 

 its very narrow corolla-tube, long calyx-teeth, sessile stamens, and 

 cordate leaves.
