Two other glabrous slender shrubby climbing species were gathered by Dr. 
Balfour in Rodriguez in Cascade Valley, without flower and fruit, which should be 
specially looked after by future visitors. 
1. Leaves oblanceolate-oblong, distinctly petioled, glossy, subcoriaceous, 2|-3 
inches by §-l inch, acute, slightly rounded at the base, with many straight erecto- 
patent veins branching from the midrib, and distinctly visible on the under side 
parallel nearly to the edge. 
2. Leaves membranous, oblong, acute, cuneate at the base, 1|~2 in. long, f-l in 
broad, with more irregular fine immersed veins anastomosing in arches just within 
the edge.
