Cockayne. — Development vf Seediuujs. 395 



Cotyledons 1-1 cm. x 7'5 iniii., oblong, oval or rotund- 

 oblong, entire, retuse or emarginate, rarely obtuse, thick, 

 coriaceous, very persistent, dull dark-green, with many 

 minute scales, especially on the under-surface, 3-nerved from 

 base ; midrib on entrance into leaf almost immediately giving 

 off two more nerves, which are parallel for a time, and then 

 converge towards apex of leaf ; petiole very short, subterete, 

 flattened above, 2mm. long. 



Early leaves alternate, stipulate, variable in shape, often 

 from oblong to linear-oblong, blackish-green on upper paler 

 on under surface, short-petioled or sessile; midrib and veins 

 swollen on upper surface, indistinct on under-surface, dotted 

 with many minute white scales ; margins entire or serrate ; 

 serrate margins with serration on one side, with one opposite 

 serration on each side, usually nearer base than centre ; apex 

 lobed to subacute. 



Later leaves pale-green at first, linear to linear-oblong, 

 tapering into very short petiole, smaller than earlier leaves 

 on main stem, usually entire, with very short apiculus at 

 end of midrib, sometimes lobed and irregularly toothed as 

 in early leaves ; veins swollen "on upper surface ; laminae 

 at angle of 45° to axis of stem, semi-vertical to horizontal. 



Stipules very small, one on each side of petiole, subulate. 



Stem of slow growth, very stiff, erect, and woody, early 

 branching with stiff divaricating branches, rather pale-brown, 

 with many flat white scales at regular intervals, younger 

 portions of branches with two rows of very short close-set 

 hairs, terete; internodes 3mm. long, more or less. 



Further development not observed. 



In one or two instances the laminae of the cotyledons 

 were partly or very nearly cleft to the base, showing how 

 a plant may be developed with more than the normal two 

 cotyledons. The toothing on the leaves seems due to non- 

 development of the nerve and accompanymg portion of lamina 

 rather than to ordinary toothing, the two lateral nerves of a 

 trinerved leaf ending in this case in the serrations, the midrib 

 alone reaching the upper portion of the leaf. Hymenanthera 

 dentata is another of the shrubby plants which grow under 

 conditions of drought and wind, and its final adult stage 

 resembles that of Coprosma acerosa, &c., treated of before.
