I believe the cultivated form with colored leaves described 
by Loureiro as Excoecaria cochinchinensis to be identical with 
Excoecaria bicolor Hassk., which being the case Loureiro’s 
name should be retained. The type of Excoecaria bicolor Hassk. 
var. viridis Pax & K. Hoffm. was from Cochin China, and the 
description agrees entirely with the specimen cited above. 
The species is new to China.

This is the first record of the species from China proper, al- 
though it had previously been recorded from Hainan Island. 
Unless Alchornea rugosa (Lour.) Muell.-Arg. is variable in the 
number of its stamens, it would seem that Pax and Hoffmann 
are wrong in their interpretation of Alchornea rugosa, and that 
they described as a new species the typical form as described 
by Loureiro under Cladodes rugosa. Loureiro describes his 
species as having eight stamens, the only character depended 
upon by Pax and Hoffmann in separating the Hainan form from 
Alchornea rugosa. In Alchornea hamanensis the staminate 
flowers have eight stamens, as does the Kwangtung specimen 
cited above, thus agreeing with Loureiro’s original description 
of Cladodes rugosa. J. J. Smith states that in all staminate 
flowers of the Javan form referred by him to Alchornea rugosa 
the number of stamens was four; Pax and Hoffmann state 
stamens 4, rarely 5 or 6. The actual specimens so closely re- 
semble each other that I strongly suspect that the species has 
a variable number of stamens, 4 to 8. Should this not prove 
to be the case, then Loureiro’s specific name will have to be re- 
tained for the form characterized by Pax and Hoffmann as 
Alchornea hainanensis, while for the common Malayan form 
the name Alchornea javanensis (Blume) Muell.-Arg. will have
