Seedling (fig. 629). 



Hypocotyl woody, erect, terete, pubescent with adpressed up- 

 turned, brown hairs, 2'3-2'9 cm. long. 



Cotyledons sessile, obovate, rounded at the apex, auricled at 

 the base and connate, forming a line round the stem, trinerved, 

 ascending, coriaceous, deep green above and shining, paler beneath, 

 glabrous. 



Stem like the hypocotyl ; 1st internode 3-5 mm. long ; 2nd 

 2 mm. ; 3rd 4-5 mm. ; 4th and 

 5th each 3 mm. 



Leaves cauline, simple, alter- 

 nate, exstipulate, sessile. 



No. 1. Always very small, 

 often deformed or linear- oblong, 

 obtuse, mucronate. 



Nos. 2 and 3. Cuneate, and 

 tapering to a long petiole-like 

 base, deeply trifid and tri- 

 nerved in the upper half, glabrous 

 above, deep green and shining, 

 paler beneath, and pubescent 

 with white, upturned, adpressed 

 silky hairs ; lobes oblong, acute, 

 or mucronate. 



Grevillea linearis, E. Br. 



(fig. 630). 



Hypocotyl erect, terete, 

 woody, about 8 mm. above the 

 soil. 



Cotyledons oblong, obtuse, 

 entire, sessile, connate at the 

 base and appearing perfoliate, 

 horizontal when full grown, 

 about 8 mm. long, and 4 mm. wide above the middle. 



Stem erect, terete, woody ; 1st internode 75 mm. long ; 2nd 

 9 mm. ; 3rd 1 cm. 



Leaves simple, entire (at least in the early condition of the 

 plant), cauline, alternate, exstipulate, sessile, coriaceous, thinly 

 hairy, light green. 



The seedling of Grevillea punicea, E. Br., is very similar to that 

 of G. linearis.
