16 PLANTS FROM NEW CALEDONIA. 
Obs. The genus Aneura is not a particularly beautiful one, but this species 
is peculiarly striking and handsome. 
A considerable number of species of Aneura are recorded by Stephani 
from New Caledonia, but none of those described by him agrees with this. 
A, elegans is pale green, longer, regularly bipinnate, pinnæ 10 mm. long 
(in A, pulera 3 mm.), stem *9 mm. x4 mm. (in A. pulera ‘6 mm. x ‘4 mm.), 
angles on both sides acute (in A. pulera rotundate), pinnæ ‘67 mm. x:17 mm. 
(in A. pulera 35 mm. x ‘07 mm.). 
A. Leratii is autoicous, stem narrowly winged. 
A. multispicata, brownish-green, flaccid, pinnæ 1:33 mm, x ‘02 mm. 
A. pembarensis, cross-section narrowly elliptical 1:17 mm.x 025 mm. 
A. plana, flaccid, pale brown, 1:67 mm. x*25 mm. 
A. subpalmata, stem 1:25 mm, x :33 mm., pinnæ 1°33 mm. x :25 mm. 
A, valida, coriaceous, 1:33 mm. x 58 mm. 
A. venosa, of which only a very imperfect description is given by Stephani 
(Sp. Hep. Suppl. vi. 1917), has numerous long flagella; A. pulera has 
none.
