ON SEEDLINGS 



Fruit consisting of four nutlets, the pericarps of which are covered 

 with coarse hooked bristles. 



Seed conforming in shape to the fruit, obovate, obtuse, exalbumi- 

 nous, considerably flattened ; testa smooth, membranous ; hilum 

 conspicuous. 



Embryo straight, filling the seed, colourless ; cotyledons broadly 

 obovate, obtuse, entire, plano-convex, lying face to face the broad 

 way of the seed with their faces to the axis ; radicle short, obtuse, 

 terete, much shorter than the cotyledons. 



In C. furcatnm, Wall., the seed is similar in all respects to that 

 of C. vulgare, but much smaller, more flattened, and the pericarp 

 is covered with proportionally longer bristles. 



Eritrichium barbigemm, A. Gray. 



Hypocotyl short, erect, terete, 1-1 '5 mm. long, green or almost 

 colourless. 



Cotyledons subfleshy, spathulate, obtuse, entire, tapering to the 

 base, covered with rather stiff hairs on the upper side, glabrous 



beneath, green, indistinctly one- 

 nerved. 



Stem erect, terete, hairy, 

 herbaceous ; 1st internode '75- 

 1-25 mm. long ; 2nd shorter. 



First leaves simple, entire, 

 cauline, opposite, decussate, ses- 

 sile, tapering to the base, ex- 

 stipulate, spathulate-linear, ob- 

 tuse, covered with rather stiff 

 hairs or bristles, green, dis- 

 tinctly one- nerved. 



Amsinckia intermedia, Fisch. 

 et Hey. (fig. 537). 



Hypocotyl erect, terete, gla- 

 brous, 1-6-2 cm. long, light 

 green. 



Cotyledons deeply bipartite, 

 divided nearly to the base, with 

 spathulate, obtuse, somewhat stalked, one-nerved, hairy, divaricate 

 divisions. When the seedling first appears above ground the 

 segments are linear, erect, but soon diverge, widen and lengthen till 

 they become spathulate. 



Leaves simple, cauline, alternate, exstipulate, hairy. 

 Nos. 1 and 2. Linear, suba ute, entire.
