Umbelliferce.] LOO CHOO AND BONIN. 263 



1. Raphiolepis? integerrima ,• foliis coriaceis elliptico-oblongis obtusiusculis basi 

 acuminatis integerrimis, bracteis deciduis, fructu (immature) anguste obpyriformi apice 

 limbo calycis cupulato truncato coronato. 



Hab. Bonin. — This plant has two long slender styles, which are glabrous as in Photinia ; but the struc- 

 ture of the limb of the calyx allies it more to Raphiolepis. The corymb appears to be simple and few- 

 flowered, there being only 4 pedicels composing it in the only specimen we have seen. 



Ord. XX. COMBRETACE^E. Brown. 

 1. Terminalia Catappa. Linn.

Ord. XXI. GRANATEiE. Don. 

 I, Punica Granatum. Linn. 



Hab. Loo Choo. — By a letter we have lately received from Dr. Wight of Madras, we learn that Mr. 

 Griffith (Hon. E. I. C. service) has now determined that this Order is truly distinct from Myrtacem, and that 

 the explanation of the structure of the fruit, given by those who unite it to the latter order, is quite erroneous. 



Ord. XXII. CUCURBITACEJE. Juss. 

 1. Cucumis sativus. Linn. 

 Hab. Loo Choo. 



1. Bryonia ; foliis petiolatis late cordatis subangulatis grosse dentatis supra 



punctis callosis albis onustis subtus glabris, cirrhis simplicibus. 



Hab. Loo Choo. — This does not agree with any published species, nor have we materials sufficient to 

 enable us to describe it. If it be B. Japonica, Thunb., that plant is very ill defined by that author. 



Ord. XXIII. CRASSULACEiE. Be Cand. 



1. Sedum uniflorum ; caulibus ramosis e basi procumbente adscendentibus, foliis 

 alternis subteretibus obtusis basi solutis glabris, floribus solitariis ramulos terminantibus, 

 petalis lanceolatis acutiusculis. 



Hab. Loo Choo.— Stems from five to six inches long, weak and slender. The petals appear to have been 

 reddish.
