LOO CHOO AND BONIN. 
[ CyperacecB. 
1. Alpinia Allugkas. Boscoe? — Hab, Loo Choo. 
This, as well as all the Monocotyledones, except some of the Graminem and Cyperacese, are so mutilated 
as to prevent our determination of the species with any degree of certainty.

1. Allium angmtum. G. Don ? — Hab. Loo Choo. 
This is the only species to which we can refer the Loo Choo plant, but it differs by the umbel being 
bulbiferous and not crowded : it may, however, be A. odorwm, of Thunberg and Loureiro, which Mr. G. 
Don calls A. Thunbergii. The stamens are exserted, simple, and arise from a broad triangular membranous 
base.

1. Dioscorea^ajoom’ca. Thunh. FI. Jap. p. 151 ?— D. oppositifolia. Lour, {an Linn.?) 
— Hab. Loo Choo. 
Rumphius’ Amb. 5. tab. 123, gives a good representation of our plant. Perhaps it is only a form of D. alata, 
but the branches are slender and nearly terete. ^

1. Commelma. polygama. Roth. — Hab. Loo Choo. 
Ord. LXII. PALMAE. Juss. 
1. Caryota urens. Linn.? — Hab. Loo Choo. 
A branch of the male spadix only is present, without leaves. ^

1. Mariscus cyperinus. VahL — Hab. Loo Choo. 
1. Chaetocyperus Limnocharis. Nees ah Esenb. ?■ — Hab. Loo Choo. 
The specimens are not sufficiently advanced to enable us to determine the structure of the fruit accurately : 
the stems are more slender than in the Indian specimens.
