know to vary exceedingly; but in regard to the former parti- 
cular, our specimens are not of sufficient length to enable us 
to come to any conclusion. But since the pinnules vary in 
regard to their situation, it is probable that the pinnz do so 
likewise. 
7. M. salicifolia. Schrad. in Getting. Gel. Anz. 1818, p. 920. 
Haz. Cape of Good Hope, Mund and Maire. This spè- 
cies, which is characterized as having the pinnae opposite, is, 
by Sprengel, united with M. sorbifolia (pinnis alternis). We 
can truly say that some of our narrow leaved specimens of 
the Mauritius M. fraxinea entirely correspond with Schlecht- 
endal’s description in his Adumbrationes. 
8, M. salicina. Sm. in Rees’ Cyclop. 
Has. New Holland? Robert Molesworth, Esq. We pos- 
sess an imperfect specimen of this plant from Sir J. E. Smith, 
and on comparing it with our narrow-leaved varieties of M. 
Sraxinea, we find it to differ in nothing except in the presence 
of copious hair-like scales at the base of the midrib. _

Has. New Caledonia, Labillardiére.— According to Labil- 
lardiére's character, this differs in its triplicato-pinnate frond, 
and, judging from the figure, in the smaller number of leaves 
(5-8) upon each pinha, from M. fraxinea, which has 30-40 
upon each pinna.

which was confounded with M. frazinea by Professor Raddi, 
is abundantly distinct, in having the foliage of a much more
