Chitonanthera filiformis is most closely allied to C. ten- 
uis (J.J.Sm.) L.Wms. (cf. below), but is easily distin- 
guished by its filiform leaves, slender stems and the de- 
tails of the flower and column.

Folia 1.5-8 mm. longa. Internodia caulium 2-4 mm. 
longa.

ets, Lake Habbema, alt. 3225 m., flowers orange-colored, August

Variety brachyphylla, at first glance, appears to be 
amply distinct, but closer study shows it to have flowers 
identical with those of the species and to differ mainly in 
the short leaves and in the short internodes of the stem.
