This species is very common in thickets in the vicinity of Can- 
ton, Loureiro’s type having been from Canton. J. Mueller 11 notes 
that Loureiro’s description of the flowers and of the inflorescen- 
ces does not conform to Croton; further it does not conform 
with the characters of any euphorbiaceous plant known from 
Kwangtung Province, but, with the exception of the fruit de- 
scription, agrees entirely with the species currently known as 
Xylosma racemosum Miq. It is clear that Loureiro either added 
the fruit description to make his species agree with the generic 
characters of Croton, or described the fruits from material 
originating from a species entirely unrelated to the flowering 
specimen described by him. I have examined the following 
specimens from Kwangtung Province, mostly from the imme- 
diate vicinity of Canton: Merrill 9850, 9993, Groff 2252, 2353, 
Levine 18, 171, 172, 177, 279, 365, 366, 371, 1749, 1809, 1829, 
2084, 3261, 3341, To Kang P'eng 2727, 2737. The local names 
recorded are wu ying shue (vicinity of Canton), ch’ui tung ts’ai 
(North River region), and chu nga lak shii (Kochow region). 
The name pa tau recorded by Loureiro should probably be ex- 
cluded as it is the same as the name recorded by him for Croton 
tiglium Linn.

Loureiro cites no definite locality, but from the fact that he 
indicated the local name pa mou yong as Chinese it is clear that 
his material was from China, and in all probability from the 
vicinity of Canton. The description definitely applies to the 
species commonly known as Aquilaria grandiflora Benth., one 
that is not uncommon in the vicinity of Canton. Loureiro’s 
description of the perianth as 6-merous was apparently due to 
an error on his part, for he enumerates the stamens as five, thus 
indicating that he was describing a 5-merous flower. I have 
examined the following Kwangtung material : Groff 2487 , Mer- 
rill 10962, Levine 996, 1400, 2070, from Tsangsheng, Wa Shau 
Toi, White Cloud Mountain, and Honam Island, the last two 
localities being in the immediate vicinity of Canton. Loureiro’s
