 Hab. Northern Island : Hawke's Bay; on the ground, Colenso. 



Plant, gregarious, smaller than mustard-seed, reddish.-to* clustered into a roundish bulb, apprised, the 

 two innermost nearly equal, and larger than the rest, their apices erect, margins not at all reflexed; nerve thickened 

 at the top, distinctly excurrent, reddish. Capsule immersed, globose, erect, on a very short, slender pedicel. Calyp- 

 tra conico-mitriform, minute.-In the allied British species, P. muticum, Schreb., the leaves are less closely connivent 

 have recurved apices, the inner peridural leaf overtops the rest, the nerve is not excurrent, margin - treflexed ; and 

 the reticulation is larger.-PLATE LXXXIII. Eig. 1 :-l, plant, natural size; 3, the same, wagmfied S 3, capsule

rioribus elliptico-lanceolatis longe acuminatis appressis crassinerviis (nervo excurrente), capsula immersa 



apiculata.— Eoo/t. Muse. Bxot. t. cv. Sehwagr. Suppl. t. 296 a. 



Hab. Northern Island : Bay of Islands; on clay hills, I. D. H., Colenso. 



Found at the Cape of Good Hope, and a variety with submuticous leaves, in Pennsylvania. Nearly allied to 

 P alternifolium Bryol. Europ., having several axillary gemmiform male flowers; but distinguished by the shorter 

 etstS ltd leaves.- JU often laterally exserted on a curved pedicel in our New Zealand specimens^ 

 m r e evidently apiculate than shown in the figure in Muse. Exot.-Some of our specimens have numerous sterile m- 

 ZZ^k with widely ovate muticous denticulate leaves, closely resembling those of Pennsylvaman specimens.
