coriaceous, more or less imbricating, subsessile, and in my 

 cultivated plants ciliate towards the base. Hooker says 

 glabrous.

(Var. with prostrate siems, rooting freely from the nodes.) 

 Seed from cultivated plant in Tarata Garden. 



Description of Seedling. 



Eoot remains enclosed in seed for considerable period ; in 

 one case the stem was furnished with two pairs of leaves 

 before it emerged, at first quite coiled up, finally descending, 

 with very many filiform lateral rootlets. 



Hypocotyle 5 mm. long, terete, green or pinkish. 



Cotyledons 5 mm. long, ovate-oblong, obtuse, green above, 

 sometimes purplish on under-surface ; midrib hardly evident ; 

 petioles connate at base. 



Leaves pale-green, pinkish, or margin more or less deeply 

 stained with pink ; topmost crowded ; earlier leaves with 

 petioles semi-erect, and laminae spreading and curving down- 

 wards often, usually narrow- or broadly-ovate, obtuse, with 

 petioles from one-third to one-half length of leaves ; more 

 mature leaves broader, almost rotund at times ; midrib 

 slightly raised on under-surface ; both surfaces dotted with 

 many minute white scales ; still later leaves obovate, almost 

 sessile, quite glaucous above, wdth a red margin. 



1st pair of leaves narrow-oblong or obovate, obtuse, green 

 on upper sometimes purplish on under surface ; midrib partly 

 evident ; petioles connate at base. 



Adult leaf (Plate XXXIV., fig. 63) coriaceous, 1-3 cm. x 

 7*5 mm., sessile, glaucous, patent, sometimes twisted towards 

 light ; margin entire, pale, slightly stained with pink ; surface 

 concave above, convex below ; midrib sunken below. 



Stem green at first, then pink or brownish ; internodes 

 short, about 2 mm. long, do not seem to lengthen, almost 

 glabrous, with a very few scattered hairs and scales. 



The variations among the seedlings seem to be slight ; 

 one has a 2nd leaf with an emarginate apex, and there is 

 some variation in breadth of leaves and in the pink stain. 

 The variations will be more marked at a later stage. V. 

 'pinguifolia is essentially a plant of the drier mountains, 

 xerophilous in structure, and not occurring, so far as I know, 

 on the western side of the dividing-range, and possibly not 

 within the region of the western rainfall.
