A. INTERMEDIA, DO. 



The seedlings of this are almost identical with those of 

 A. subvelutina. When grown under similar conditions they 

 are usually quite indistinguishable, and it is only when A. 

 intermedia is a foot or two high, and nine or twelve months 

 old, that the leaves begin to be petiolate. 



A. LANCEOLATA, OaV. 



Hypocotyl erect, terete, glabrous, reddish, 1*5 cm. long. 



Cotyledons large, foliaceous, glabrous, petiolate, reniform 

 entire, except at base which is cordate, veins prominent, 

 purplish red on under surface, laminae 15 x 13 mm., 

 petioles 6 mm. 



Leaves entire, opposite, decussate, lanceolate, obtuse, 

 sessile, cordate at base with rounded auricles, paler on 

 under surface when dry, purplish-red in early stage, covered 

 with fine glandular hairs, lateral veins open and parallel, 

 intramarginal vein not well defined, but in older leaves 

 close to edge. First pair of leaves 2*8 cm. x 0*6 cm., 

 second pair 8 cm. x 0*8 cm., third 3*5 cm. x 1 cm. Stem 

 terete, reddish, bristly. First internode 2 cm., second 2 

 cm., third 1*8 cm.
