All this African material is alike, but in matching it against the numerous sub- 

 species of J. procumhens found in India, different views have been taken, some 

 uniting it with J. simplex, D. Don. 



30. J. insulariSy T. Anders, in Journ. Linn. Soc. vii. 40. Herba- 

 ceous; branches 3 ft. long, straggling, angular, more or less hispid; lower 

 nodes distant, often flower-bearing. Leaves up to 3i by |-1 in., narrowed 

 at either end, slightly hairy on both surfaces or glabrate; petiole ^-1 in. 

 long. Flowers 3-1 in each axil, sessile; floral leaves \-\ in. long, round or 

 obovate, some narrower often added. Sepals 5, subequal, ^-J- in. long, 

 broad-lanceolate or subovate, scarcely acute, sparsely hispid. Corolla 

 exceeding J in. in length, purple ; tube very httle dilated at the top ; 

 anticous lobe much longer than the posticous 2-fid lobe. Filaments 

 glabrous ; one anther-cell below the other, tailed ; pollen ellipsoid, with 

 2 stopples, longitudinally banded, with several rows of tubercles on 

 the band. Ovary glabrous ; style base hairy. Capsule exceeding J in. 

 long, glabrous, 4-seeded, with a short thick solid stalk ; seeds reticu- 

 late rugose. — Lindau in Engl. <fe Prantl, Pflanzenfam. iv. 3 B. 349,

Soyaux, 296, is identical with Vogel's Fernando Po plant. Vogel's specimen at 

 Kew is noted on the herbarium sheet " dimorphic fruit," which is very likely to be 

 the case ; but I can find no dimorphic fruit on any of the West African species of this 

 group. It is possible that the herbarium note was grou; 1 on J. Lindaui, which 

 is extremely like J. instdaris, but has linear very acute sepaU.
