ON SEEDLINGS 



green or soon becoming brownish-purple, pubescent, with hooked, 

 bent, or branched hairs, ultimately shrubby, twining ; 1st internode 



and frequently the 2nd unde- 

 veloped ; 2nd when developed 

 1-2 mm. long ; 3rd 3'5-4'5 mm. ; 

 4th 2-3 mm. 



Leaves simple, cauline, alter- 

 nate (first and second often oppo- 

 site), exstipulate, petiolate, alter- 

 nately penninerved, with the nerves 

 running straight into the lobes or 

 teeth, somewhat pubescent on the 

 margins and nerves, especially 

 when young, with bent, kneed, or 

 forked hairs, deep green and shin- 

 ing above, pale beneath ; petioles 

 channelled above, convex on the 

 back, slightly pubescent, deep 

 green. 



Nos. 1 and 2. Triangular, tri- 

 lobed; lateral lobes cuneate, bi- 

 dentate ; middle lobe entire or 



tricuspidate. In very small weak seedlings the first two leaves are 



frequently merely cuneate, tricuspidate. 



Nos. 3 and 4. Triangular-ovate, trilobed, longer and larger than 



the first two ; middle lobe trifid or coarsely serrate ; lateral lobes 



bifid or serrate, mostly on the posterior side. 



Billardiera fusiformis, Labill. 



Hypocotyl as in B. longiflora, stained red, 8-15 mm. long. 



Cotyledons long, linear, acute, tapering to the base but scarcely 

 petiolate, dark green, glabrous, one-veined. 



Stem with primary internodes undeveloped. 



First leaves alternate, ovate-oblong, obtuse, lobed, coarsely and 

 obtusely serrate, glabrous, green, pinnatinerved.
