8. LlTOBROCHIA DIVARICATA, Sp. Nov. 



L. stipitibus Icevibus castaneis semiteretibus hinc canalicidatis ; frondibus 

 ternatis, divisionibus primariis bipartitis patentibus, seciindariis pin- 

 natis; pinnulis sessilibus alternis linear i-lanceolatis acnminatis pin- 

 naiipartitis, laciniis lineari-oblongis subfalcatis apice obtuso crenulaiis. 



Hab. Feejee Islands : on the margin of cultivated lands. 



Plant from 4 to 6 feet high, forming dense thickets. Fronds 

 smooth, ternate; the primary divisions from 2 to 2£ feet in length, 

 spreading, and divided into two equal pinnate branches. Pinnae 

 deeply pinnatifid, alternate, approximate, from 35 to 40 in number, 

 sestsile or subsessile, linear-lanceolate, and narrowing into an entire cre- 

 nulate point of about lh inches in length. Segments from 8 to 10 lines 

 long, by 2i lines broad, linear-oblong, obtuse, subfalcate, the point cre- 

 nidate. Sinus rounded at the base, the width outwards generally 

 about half that of the segment, but sometimes towards the base of the 

 pinnae the intervening space is equal to the breadth of the segment 

 itself. jStijje thick, smooth and glossy, of a dull broicn colour, semi- 

 terete, channeled in front. Rhachis, costa, and veins of a reddish- 

 brown hue ; the lower veins of each opposite pair of segments rectan- 

 gularly combining, forming a low arch parallel to the rhachis of the 

 pinna; the outer ones irregularly and arcuately uniting: venules 

 usually free. 



Distinguished from the preceding species by the fewer divisions of 

 its fronds ; the longer, more acuminated, and deeply pinnatifid pinnge • 

 and the larger and more obtuse segments, with the rhachis, costa, 

 and veins of a darker colour. 



***** Frondes tripinnatce, divisionibus idtimis erenatis vel sinuatis.
