DESCRIPTION OF THE SPECIES. 205 



Feildeniopsis crassinervi.s, sj). nov. 



Plate LXXXV. FiK. '>. 



Plant with the generic character, having- very stron<r broad nerves, 

 which are sharply defined like threads in the dense leaves, the latter having- 

 a glossy look, and seeming to narrow so as to form a sheathing or clasping 

 base. The nerves of this species are quite like tliose of Heer's species FVil- 

 denia Mo!isiana,^ curving around to abut at the sunuiiits of the leaves, and tlie 

 points of meeting are connected by a strong nerve, which descends and 

 seems to split up to form the central pair of nerves. 



Locality : The nlant occurs only at Kankey's and is very rare. 



BAIEROPSIS, gen. nov. 



Leaves Ijorne towards the ends of the branches? ; leafy branches pin- 

 nately arranged, opposite or subopposite, in the same plane with the leaves, 

 diminishing in ascending in the size and number of the leaves; towards the 

 sunnnit of the leafy stem the leafy branches reduced to simple leaves ; the 

 leafy stem terminated by a simple leaf similar to those of the brandies and 

 stem lower down ; leaves on the lower branches pinnately arranged, subop- 

 posite or alternate ; lower leafy branches terminating, as does the main stem, 

 by a single leaf; leaves attached pinnately to the branches by short jiedi- 

 cels, in shape like a fan, with wedge-shaped bases, divided nearly to the l)ase 

 into several principal segments or lacinia;, usually two or three in number, 

 these in tui-n divided into a varying number of subordinate segments, and 

 the latter divided into a number of ultimate Iacini.ie, which are sti-ap-shaped, 

 of varying width and length, and end in teeth : the lacini;v of various orders 

 subdivided dichotoniously, diverging slightly ; tlie nerves branch repeatedly 

 in a dichotomous manner, beginning in tlie pedicel, the branching taking 

 place at varying heights; the nerves diverge in a flabellate manner, and 

 one or two of the ultimate branches end in the teeth terminating- the ulti- 

 mate lacinia?; they are slender but distinct; fructification not positively 

 made out, but apparently in the form of very small rounded or elliptical
