272 LOO CHOO AND BONIN. iCyperacea. 



1. Alpinia Allughas. Roscoe? — Hab. Loo Choo. 



This, as well as all the Monocotyledones, except some of the Gramineas and Cyperaceae, are so mutilated 

 as to prevent our determination of the species with any degree of certainty. 



Ord. LVIII. LILIACEiE. Juss. 

 1. Lilium pomponium. Thunb. Fl. Jap. p. 134 Hab. Loo Choo. 



Ord. LIX. ASPHODELE^. Br. 

 1. Allium angustum. G. Don ? — Hab. Loo Choo. 



This is the only species to which we can refer the Loo Choo plant, hut it differs by the umbel being 

 bulbiferous and not crowded : it may, however, be A. odorum, 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. Dianella graminifolia. Linn. — Hab. Loo Choo. 



Ord. LX. DIOSCORE^E. R. Brown. 



1. Dioscorea japonica. Thunb. Fl. 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. 



Ord. LXI. COMMELINEjE. R. Brown. 

 1. Commelina polygama. Roth. — Hab. Loo Choo. 



Ord. LXII. PALM^. Juss. 



1. Caryota urens. Linn. ? — Hab. Loo Choo. 



A branch of the male spadix only is present, without leaves. , 



Ord. LXIII. CYPERACE^. Juss. 



1. Abildgaardia Rottboelliana. a, spica solitaria demum subnutante. Nees ab Esenb. 

 Mst. — A. monostachya. var. indica. Vahl ; Kunth, En. 2. p. 24-7. — Hab. Loo Choo. 



1. Cyperus hexastachyus. Rottb. — Hab. Loo Choo. 



1. Mariscus cyperinus. Vahl. — Hab. Loo Choo. 



1. Chastocyperus Limnocharis. Nees ab 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.
