LEMBOPHYLLACEAE. 
CAMPTOCHAETE Reichdt. in Novara Exped. i, 190 (1870). 
The genus Camptochaete, which may be said to have its head- 
quarters in New Zealand, is entirely confined to Australasia and Mela- 
nesia, with the exception of C. gracilis, which is also found in Chile, 
and a single somewhat doubtful species from Ceylon. The generic 
cabana are not too easy to define, but the ioe are generally 
easy to recognize, from the rigid, subdendroi d habit, with almost 
poo > the small, ovate, concave, scariose leaves, usually obtuse 
or Bery shortly pointed, not acu minate, nerveless or nearly so, and 
the very narrow, small, usually sigmoid cells. The fruit also is gener- 
ally tke aa from the upper part of the stems. The habit, hivechee, 
f C. gracilis, and of some forms of the other species, is widely differ- 
ent from the ‘typical habit, and the foliation of C. pulvinata is not at 
all that of ai normal t 
One feature of the ger nus agi notice, the tendency of the 
dense be ane species to produce slender, extended, more or less 
complanate forms, both in branching and in le af arrangement, with 
laxer branches often ending in — oi a prolonga- 
tions. C. deflera Jaeg. is one of these forms, derived from C. arbus- 
cula, as was suspected by Wilson, and as is cae from prey numer- 
ous ei eine forms to be found when a —_ series is studied. 
mulosa has an exactly parallel form, and less frequently C. 
mnie (C. spurro-deflexa (C.M.) Broth.) ; and I have little doubt 
that C. flagellifera Broth. is simply a similar ‘form of the New Guinea 
C. subporotrichoides Broth. & Geh., with which it grows, and from 
which it differs in no structural characters.
