Cockayne. — Development of Seedlings. 271 



1st leaf subcordate, irregularly and deeply crenate, almost 

 lobed, ciliated with short hairs, also a few hairs on the petiole ; 

 remainder of leaf glabrous, pale apple-green on both surfaces, 

 palmately 5-nerved, with the veins much reticulating ; petiole 

 three-quarters the length of lamina, channelled. 



Later leaves up to 6th leaf broadly cordate, sometimes 

 almost rotund, with cordate base; more or less lobed, some- 

 times almost trilobed ; lobes irregularly crenate, ciliated ; re- 

 mainder of leaf as in description of 1st leaf. 



Stipules inserted on stem on inner side of petiole, subulate, 

 often stained pink ; at first very soft and succulent, protecting 

 young bud, afterwards smaller through drying, finally de- 

 ciduous. 



Stem of slow development, with early internodes very 

 short (1st internode is 2 mm. long by time 1st leaf is 11 mm. 

 long), terete, pale-green marked with purple, furnished with a 

 few remote stellate hairs. In plant about eight months old 

 the stem, exclusive of the now woody hypocotyl, is 14 mm. in 

 length, still soft and succulent, green deeply stained with 

 brownish-purple ; later internodes considerably larger than 

 the earlier ones ; steilate hairs more numerous on upper por- 

 tion than on lower portion of stem ; from the lower internodes 

 all the leaves have fallen, a few shrivelled stipules still per- 

 sisting ; the leaves above have all been developed since the 

 winter. 



Besides the above-described artificially raised seedlings, 

 I have one which was collected at the base of Mount Torlesse 

 in April, 1898, and which has been kept since that time in 

 the shade-house. It is now 16 cm. tall, with three main 

 stems, a few short side branches, and about fourteen leaves. 

 The largest leaf is (lamina) 2-5 cm. x 2-6 cm., ovate, with 

 cordate base ; margin lobed and crenate ; deepest lobes 5 mm. 

 in depth ; apex obtuse. The other leaves are smaller and 

 more approaching reniform in outline, being considerably less 

 drawn out at the apex. The stems of recent growth are 

 twiggy and slender, with internodes + 15 mm. in length. All 

 last season's leaves fell off in the autumn or during the 

 winter, notwithstanding the climate of the shade-house, a 

 much milder one than that of the natural station of the 

 plant. 



There are two quite distinct forms of Gaya lyallii, one — 

 G. lyallii proper — -being confined, so far as I know, to regions 

 in the South Island of New Zealand exposed to the great 

 western rainfall ; and the other form — i.e., the one now under 

 consideration — being found without the limit of the above 

 rainfall in the eastern lower mountain region, where it grows 

 chiefly at the base or on the slopes of river-terraces or near 

 the outskirts of the Fag us forest. The adult leaves of Gaya
