Hab. Massacre Bay, Cook's Straits, Lyall. 



Fronds tufted, 4-5 inches long, |-1 inch broad, bi-tri-pinnatifid, the latinise narrow, the ultimate ones not 

 more than a line in breadth, delicately membranaceous, crisped and waved. A strong midrib runs through the 

 principal rachis of the frond, but without emitting lateral branches to the lobes. These lobes have slender midribs, 

 which commence at the base of the lobe, and disappear nearly at its apex. The young marginal lobes are faintly 

 costulate in a similar way. Apices acute, and margin quite entire. 



In our specimens the midrib of the primary frond emits, in the upper part, very numerous, minute, lanceolate 

 leaflets, which are perhaps afterwards developed into new fronds ; if so, old plants must be very dense and intricate. 

 We have seen no fruit.

Dr. Lyall's specimens agree very well with the specific character, and also, except in size, with a specimen 

 received from Dr. Montagne. They are about 10 inches long, the stipes nearly 3 inches before it branches, and 

 strongly costate. The lamina is palmato-dichotomous, the segments linear, subeuneate, the lower ones crisped at 

 the margin, the upper slightly undulate, the terminal lobes linear-oblong, and very obtuse. The costa of the stipes 

 divides into several branches, one of which is directed to each of the principal lobes of the frond, and is continued 

 upwards until it is gradually explanated and lost near the apex. Tetraspores in minute, dot-like sori, aggregated in 

 the upper lobes, over which they are thickly scattered.— The habit of this species is very similar to that of Botryo- 

 glossum platycarpum.
