OX SEEDLINGS 



the chalaza where it is attached to the embryo-sac, and most often 

 with a shallow sinus, notched at the base of the inner face where 

 the short radicle and small plumule are seated ; plumule attached 

 to the inner face of the cotyledons a little above the base. 



Seedling. 



Primary root and hypocotyl very similar to those of Q. Ilex. 

 Cotyledons in every respect similar to Q. Ilex, remaining in the 

 nut and auricled at the base. 



Several of the primary leaves are reduced to scales. First 

 green leaf obovate-oblong, bluntly and shallowly lobate at the apex. 

 Succeeding leaves obovate or obovate-oblong, irregularly lobed, 

 with strong ascending nerves running into the irregular lobes, gla- 

 brous except on the midrib above and the 

 principal nerves beneath where they are 

 pubescent, pale green, often suffused with 

 brown. 



Quercus Ilex, L. (fig. 670). 



Primary root long, woody, flexuose, 

 tapering, dark-coloured, wiry. 



Hypocotyl woody, subterranean, very 

 stout, dark-coloured, flexuose, more or less 

 distinct from the root. 



Cotyledons subterranean, thick, fleshy, 

 applied face to face in the testa, and convex 

 on the back, longitudinally wrinkled, obo- 

 vate-oblong in outline, retuse at the apex, 

 petiolate and produced behind the petiole 

 into a thin appendage ; petioles both curved 

 to one side of the stem, about T2 cm. long ; 

 lamina including auricle 2-25 cm. long, 

 1 cm. wide. 



Stem woody, erect, terete, somewhat zig- 

 zag from node to node, pale green, stellately 

 pubescent, hoary when the tree attains some 

 age; 1st internode 1 cm. long; 2nd- 

 4th each about 1 mm. ; 5th 5'5 mm. 

 6th 2-5 mm. ; 7th 1 cm. ; 8th 1-75 mm. 

 9th 5 mm. ; 10th 2-5 mm. ; llth 2-5 mm. 

 12th 3-5 mm. ; 13th 2 mm. These lengths 

 are liable to some variation in different seedlings, but they indicate 

 the general tendency.
