6. O. pectinata, Pr. — Stipites and rachises naked ; pinnas in two or 

 more laxly extending pairs, 1-2 it. 1., with distant alternate branches, 

 ■^hich are once-forked, or the inferior ones again branched with similar 

 forked pinnulae, petioles slender, cartilaginous-margined, devoid of leaf- 

 segments but usually with foliaceous bracts in the axils at the base ; 

 piunulsD 6-10 in. 1. 1^-2 in. w., linear lanceolate acuminate, outer side 

 wider at the base than the inner, which is usually somewhat reduced 

 there ; ultimate segments linear, bluntish, emarginate, 1-1^ in. 1. 2 1. 

 w. at the rather dilated and connected bases, pale green above glauc- 

 ous beneath, naked or slightly rusty-tomentose on the veins, which are 

 2-3 times forked, sori usually not plentiful ; sporangia in clusters of 

 12 (13) or less; Hook, and Grev. Icon. t. 14. Mertensia, Willd. 

 Dicranopteris, Bemh. 



Grenerally diffused among the lowlands, and ascending to nearly 

 6,000ft. elevation. Much more common than its ally, dichotomay to 

 which it bears a general resemblance but is clearly distinguished by 

 habit. Its chief features are the long lax pinnae, the branches of 

 which are arranged alternately, the slender petioles being flattened on 

 the face and slightly margined by cartilage, and the absence of the 

 axillary pair of pinnulae which subtend the fork of that species. There 

 is an intermediate form common about Mt. Moses, broader with the 

 habit generally of pectinata but approaching dichotoma by a tendency 

 to develop a pair of deflex^d basal pinnulae. The mainland form, found 

 too on some of the West India Islands, is much narrower in its leaf- 

 age, and with rusty hairs clothing the veins beneath.
