Elaocarpece.'X LOO CHOO AND BONIN. 259 



Ord. III. PITTOSPOREiE. Brown. 



I. Pittosporum pauciflorum. Hook, et Am. supra p. 168 /3? foliis obtusis, petalis 



duplo longioribus, fructu trivalvi. 



Hab. (3, Loo Choo (in fruit) ; Bonin (in flower). — Our var. a, from China, appears to us to be the Cortex 

 filarius of Rumph. Amb. 7. p. 13. t. 7 ; but is very different from the P.ferrugineum of Aiton. 



Ord. IV. CARYOPHYLLEiE. Juss. 



I. Dianthus Chinensis. Linn. — Var. floribus subaggregatis. 

 Hab. Loo Choo. 



1. Arenaria serpyllifolia. Linn. — Thunb. Fl. Jap. p. 186. 

 Hab. Loo Choo. 



2. A. procumbens. Vahl, ? — Var. angustifolia. 



Hab. Loo Choo. — Of this only a small fragment exists in the collection ; it may prove to be a new species, 

 its leaves being subulate : like some specimens of the true A. procumbens, the habit is that of A. media, but 

 there are no scariose stipules. The capsule is 5-valved. 



Ord. V. MALVACEAE. Juss. 



1. Hibiscus Rosa-sinensis. Linn. 

 Hab. Loo Choo. 



1. Paritium tiliaceum. S. Hil. — Hibiscus tiliaceus. Linn. — j3? foliis utrinque glabris 

 basi rotundatis. 



Hab. a, Loo Choo. — /3, Bonin. — The specimens of both are very imperfect ; we have doubts if /3 be not a 

 distinct species ; the structure of the flower, calyx, and involucel, however, do not differ from the usual form 

 of the plant. 



1. Sida alba. Linn. — Wight and Am. Prod. Fl. Penins. Ind. Or. 1. p. 58. 



Hab. Loo Choo. — Better specimens of our Sida rhombifolia, from China, (vide supra p. 169), prove our 

 plant to be S. microphylla. Cav. 



Ord. VI. EJ^EOCARPE^I. Juss. 



1. Elteocarpus photinimfolius ; arborescens, foliis petiolatis alternis cuneato-oblongis 

 subacuminatis serratis, serraturis incurvis acutis, axillis subtus glanduliferis, petiolis 

 eglandulosis, racemis simplicibus ex axillis hornotinis folia subasquantibus, staminibus 

 plurimis, antheris apice barbulatis. (Tab. LIII.) 



Hab. Bonin. 



Glaber. Ramuli subangulati. Folia obovata vel obovato-oblonga, obtuse ac brevissime acuminata basi 

 cuneata,in petiolum attenuata, coriacea, l£-2$ poll, longa, J-li lata, margine subrecurva, versus basin remote, 

 versus apicem copiose, serrata, serraturis incurvis glandula apiculatis, venis primariis inferioribus ad axillas
