Description. The form y tenera becomes nearly a foot long, and is flaccid and 
slender. The frond has a short, generally 5—6 cm. long, main axis which is 
densely beset with short, 4—5 mm. long, rigid, appressed secondary axes, some of 
which are plainly remains of branches, while others are side-axes that have stopped 
in their growth (leaves). The latter have generally a cylindrical or almost spindle- 
shaped form, tapering commonly somewhat towards the base. Irom the remains of 
the branches new side-axes may be developed. Besides, there issue from the short 
main axis, which has ceased to grow longer, one or more, but commonly only a little 
number, of long, flaccid, slender, repeatedly racemose branch-systemes, which are lincar- 
lanceolate in circumference, and have a distinct main axis, beset with short, scarcely 2 
cm. long, 
few, scattered, simple branches, often incurved in the shape of a sickle and attenuated 
thin branchsystems of the second order, oblong-lanceolate in periphery, and 
. \ . . ’ 
towards the base and the tip. In other specimens the main stem puts forth some 
few branches dissolved at the top and resembling the main stem. In this case it is 
these that give rise to the long, flaccid branch-systems.
