PHILIPPINE URTICACEAE.

Bontoc, Bauco, Vanoverbergh 1010. The leaves of the two last are less coriaceous 
than the type, so that this may not be a valid differentiating character, otherwise, 
they are as described above. 
This species has hitherto been identified as D. longifolia (Burm.) Wedd., but 
on comparison with material of that species from Sikkim, Craib 515, 594, an< l 
of D. edulis Wedd. from China, Henry 10536, 12318 A, it seems much more distinct 
from either than they are from one another, and of the two slightly nearer D. 
edulis. It differs distinctly from both in the coriaceous narrower leaves, and 
further from D. longifolia by its smaller glomerules and less-branched inflorescence. 
The pistillate perianth of Debregeasia is always described as adnate to the 
ovary: not only in the Philippine species but in the Asiatic it seems to be easily 
separable, whereas in fruit the achene has hardly increased in size and is very 
loosely inclosed. The structure of the flowers of the Philippine and Asiatic 
material is identical. 
Debregeasia is one of the names taken up by Weddell from Gaudichaud: in 
the Bot. Voy. Bonite, there is merely a plate, the explanations not appearing till 
1866, the genus therefore dating from Weddell’s monograph, 1857. There is an un- 
doubted older name, Morocarpus “ Sieb. & Zucc., 1846: it is not used here, because 
there is an older Morocarpus , 53 The latter is regarded as a synonym of the still 
older Chenopodium Linn., and according to the Vienna Code, should be taken up 
for the genus. Leucocnide Miq., 54 1851, is generally cited as another synonym, 
but it is a mixture of two genera, the first two species being Leucosyke : it is here 
held to be typified by the species now known as Leucosyke capitellata.

The species was originally collected by Nee, both in the Marianne Islands and in 
Mindanao, and was described by Weddell, with doubt expressed as to its generic 
position, on account of the absence of pistillate inflorescence. This but not the 
staminate is present on the more recent Mindanao material, and the remarkable 
nature of the inflorescence led to its too hasty publication as new, doubt being
