a peduncle shorter or longer than the supporting leaf, rarely a poorly devel- 

 oped panicle. It is probably the same form as understood by Trim EX, Fl. 

 Ceylon III p. 390, Drake del Castillo, Flore Polyn. Franc, p. 158, etc. 

 under B. diffusa. But according to CHOISY in DC. Prodr. XIII: 2 p. 452 this 

 has the leaves green on both sides, and my plants agree better with his de- 

 scription of B. repens L., but typical repens has only been reported from Africa. 

 HEIMERL in Exgler & Praxtl, Nat. Pflzfam., regards B. diffusa as a col- 

 lective species, of which B. repens is one of many forms. Typical B. diffusa 

 is a large plant with a well developed panicle, but there are specimens in 

 herbaria recognized as diffusa but with single axillary umbels and also inter- 

 mediate forms. The leaves are sometimes conspicuously glaucous beneath. 

 The long peduncles in my form remove it from typical B. repens.

(Sesuvium portulacastrum L. is reported, without any indication of the 

 source, for Easter Island by HEMSLEY 1. c. Mr. HUTCHINSON kindly informs me 

 that there is no specimen from this place in the Kew Herbarium, nor has it 

 been quoted by any other author. Its occurrence is, of course, quite possible, 

 but requires further evidence.)
