DESCEirTION OF TUE SrEClES. 233 



Lahicopsis longifolia, sp. nov. 



Plate CII, Figs. 7, 8; Plato CIII, Figs. -2, :! ; Plafo CLXV, Fig. -J ; Plato CLXVIII, Figs. 5,6. 



Leafy stems comparatively very stout, branching- rarely, witli the 

 ultimate branches in the same plane and alternate ; leaves narrow, about 

 .5™'" or under in width, very long in proportion ; portions seen are over 

 3"'" long and not entire, grouped occasionally in bundles as in Larix, more 

 commoidy scattered singly and attached by the unnarrowed bases, flat and 

 thin, deciduous on the older branches; nerves not certainly made out, 

 apparently one for each leaf. 



Locality : Fishing hut above Dutch Gap Canal. 



The plant is rather rare, and is generally found in a very fragmentary 

 state or in the form of detached leaves. The removal of the leaf-bundles 

 leaves sometimes quite distinct dot-like scars on the upper surface of tlie 

 stems. Considering the narrowness of the leaves the stems are remarkably 

 thick. Owing to the crossing of the leaves in superposition thev often 

 look as if they split into branches, and then they remind one strongly of 

 Heer's geuus FJwunkopsls, but they certainly never fork. 



Laricopsis angustifolia, sp. nov. 



Plate CII, Figs. 0, 10; Plato CIII, Figs. 1,4. 



Twigs slender, brandling sparingly; leaves exceedingly narrow and 

 hair-like, entire length not seen, but certainly ecpialing S'^"', thin, lliit, 

 scattered over the surface of the stems or grouped in bundles ; nerves not 

 seen. 



Localities : Fishing hut above Dutch Gap Canal ; entrance to Trent's 

 Reach; rare. 



These leaves often do not surpass .2""" in width. As in tlie case of 

 the preceding species, they are always broken off towards the tips, so that 

 their true length can not be made out. The leaves as now seen are all 

 attached to the sides of the stems apparently, but this is no doubt due to 

 the fact that they, in man}- cases at least, come from tlie under sides of 

 the stems, being held in place by the superposition of tlie latter. The 

 grouping of the leaves in bundles occurs irregularly and rather rarely.
