﻿106 Dixon: New and rare Australasian 



Judging from Dus6n's specimens of Th. arhusculans Mr. 

 Chadwick's gatherings represent a young, not fully grown form 

 of the plant. 



Thamnium latifolium elongatum Dixon, var. nov. 



Caulis primarius filiformis, secundarius pendulus flexuosus 

 mollis, semipedalis et ultra, subpinnatim, distanter brevi-ramulosus , 

 ramis 1-2 cm. longis. Cetera ut typ. 



Habitat: Mt. Bruce, Wairarapa, New Zealand, June 19, 1913, 

 W. Gray 200. "Probably growing pendent from a tree with 

 Meteorium" [i. e. Papillaria], W. Gray in litt. 



There has been some little doubt as to the identity of the New 

 Zealand species with Porotrichum latifolium V. d. B. & Lac. of 

 Java; partly on grounds of geographical distribution, partly, per- 

 haps, on the ground that the New Zealand plant is as a rule more 

 densely and repeatedly branched and less flexuose than the Javan 

 (the New Zealand plant was first described by Lindberg as Th. 

 australe, but was afterwards referred by Kindberg to Th. latifolium 

 [V. d. B. & Lac.]. Kindb.). If this is the case the plant under 

 consideration should remove all hesitation on that score, for it 

 comes much nearer in habit to the Javan form, though far longer 

 (some stems reaching to 8 inches in length) ; and in fact if the 

 plant figured (Bry. jav. pi. 188, f. 2) were three times the length, 

 it would give a very fair representation of the present remarkable
