Chiengmai, in deciduous jungle on Doi Sootep, 720-750 m., Kerr, 

 676 cj', 676a Q. 



In describing the above species, which is very closely allied to 

 A. Moritzii, I have taken into consideration A, Moritzii only as 

 originally described by Mueller. 



Jatropha gossypifolia, Linn. — F.B.I., v. p. 383. 



Chiengmai, 300 m., Kerr, 712 — " often abundant on waste 

 groimd." 



Distr. Tropics. 



Kerr's plant belongs to the variety elegans, Muell.-Arg. — Pax, 

 Engler Pflanzenr., Euphorb.-Jatroph., p. 26. Pax I.e. p. 50 refers 

 Zimmermann's 27 and 145 to J. jjandurifolia, Andr., var. lafifolia, 

 Pax, but it would probably be equally right to follow Williams and 

 refer them to J. hastata, Jacq.

Croton laevifolius, Blume, var. ? 



Chiengmai, Doi Sootep, in evergreen jungle, 660 m., Kerr, 1074. 



There is no type of this . species in Herb. Kew. The Siam plant 

 differs from the Khasia specimens, referred here by Mueller, in 

 the indumentum which, though of a similar nature, is more per- 

 sistent and more pronounced on the inflorescence.
