434 ON SEEDLINGS 



penninerved, with the tips recurved and uniting, each with the one 

 above it, glabrous and deep glaucous-green above, cartilaginous and 

 ciliate at the margin, hairy beneath with adpressed hairs and paler ; 

 petioles channelled above, dilated at the base, hairy with adpressed 

 hairs, semiterete in the seedling, angled and striate in the adult 

 leaf; stipules scarious, adnate by one edge to the petiole, free only 

 at the apex in the seedling stage, but having a subulate-ovate, acumi- 

 nate free part in the adult plant, and one- to three-nerved or more. 



No. 1. Orbicular, slightly cordate at the base, otherwise entire. 



No. 2. Rotund-oblong, emarginate, cordate at the base. 



No. 3. Broadly oval-oblong, cordate at the base, emarginate at 

 the apex. 



No. 4. Pinnately three- to five- foliolate ; leaflets broadly oval or 

 oblong-oval, slightly emarginate at the apex, terminal one the largest. 



Radical leaves on the adult plant simple and cordate-orbicular, 

 or much more frequently imparipinnate, with cordate, minutely cus- 

 pidate, entire, alternate or opposite pinnules ; terminal one largest. 



Hedysarum capitatum, Desf. 



Hypocotyl erect or decumbent, terete, glabrous, pale green 

 mottled with crimson, 8 mm. to 2 cm. above ground and projecting 

 between the valves of the prickly seed-pod, which is often borne up 

 by it. 



Cotyledons large, foliaceous, glabrous, subcoriaceous or fleshy, 

 rising above ground, petiolate ; lamina obliquely obovate, obtuse, 

 obscurely trinerved or binerved, entire, 1*4 cm. long, 1 cm. broad ; 

 petioles connate by then: contiguous edges and lying to one side of 

 the stem, broad, 2-4 mm. long. 



Stem herbaceous, short, decumbent or suberect, pubescent, terete, 

 slightly ridged, pale green, mottled with crimson ; internodes irregu- 

 lar and frequently undeveloped. 



Leaves compound, imparipinnate, cauline (at first appearing 

 radical from the non-development of the internodes), alternate, 

 stipulate, petiolate, glabrous above but pubescent or almost silky on 

 the underside, and also on the rachis and petioles ; petioles subterete, 

 channelled above, dilated at the base ; stipules adnate to the petiole 

 for one-half their length, with ovate -subulate, acuminate points, 

 crimson ; leaflets shortly petiolulate. 



No. 1. Five-foliolate ; leaflets oblong, obtuse, apiculate, opposite. 



No. 2. Seven-foliolate ; leaflets opposite, oblong-oval, obtuse, 

 apiculate. 



t No. 3. Ten-foliolate ; leaflets alternate ; lower obovate, small ; 

 upper larger, oblong, obtuse, apiculate.
