and Central America, Australia, and New Zealand. 
1. Colobanthus quitensis, Bartl. in Presl, Relig. Henk. ii. p. 13, t. 49. fig. 2.

| 9, SPERGULA.

This genus consists of two or three very widely dispersed weeds of cultivation, which 
will doubtless be found in Mexico. 
1. Spergula arenarioides, Ser. in DC. Prodr. i. p. 395; Calques des Dess. FI. 
Mex. 55. 
Mexico (Mogino & Sessé). 
Not a true Spergula; perhaps a species of Arenaria. 
10. SPERGULARIA. 
Spergularia, Pers. Syn. i. p. 504; Benth. et Hook. Gen. Plant. i. p. 152. 
A small genus of three or four widely diffused species, growing chiefly on the sea-coast 
and in salt marshes; and the apparently new species described below. 
1. Spergularia neglecta, Syme, Eng. Bot. ii. p. 129, t. 255. 
Mexico, region of San -Luis Potosi, 6000 to 8000 feet (Parry & Palmer, 58). 
Hb. Kew. 
This may be a distinct species; but in the present condition of the genus it is diffi- 
cult to determine ; moreover the specimens are small and stunted.
