596 cxxxvii. JUGLANDEJE. (J. D. Hooker.) \_Engelhardtia. 



lous, hispidly pubescent ; male deciduous ; flowers very small, bracts entire ; anthers 

 sessile; fern, larger, bract 3-lobed. Fruiting bract 2-3 in.; lobes scarious and 

 reticulated, lateral sbort spreading, midlobe linear-oblong, reticulately nerved on 

 each side the midrib. Nut globose, |-^ in. diam., crustaceous, villously hispid. 

 Roxburgh's description of Juglans pterococca is made up of male flowers of E. Wal- 

 lichiana (which is the J. pterococca of his Icones), and the female of E. spicata from 

 Silhetl The plate in Wallich's Plant. Rar. of E. Rox~burghiana,.\$, a copy of Roxburgh's 

 drawing of E. Wallichiana (inscribed Juglans pterococca), in which the nut is 

 erroneously figured as hairy.

 Possibly only a form of E. spicata with sessile or subsessile leaflets. 



3. E. Colebrookiana, Lindl. in Wall. PL As. Rar. iii. 4, t. 208, and 

 Cat. 4941 ; branchlets and petioles stout densely tomentose, leaflets 2-4 in. 

 petiolulate rarely sessile broadly or narrowly oblong obtuse or tip rounded 

 rarely acute tomentose beneath, male spikes hispid, fruiting spikes 4-6 in., 

 nut hirsute. Cas. DC. Prodr. xvi. ii. 141 ; Brand. For. FL 499 ; Gamble

This again is, I think, and as Brandis suspects, a form of E. spicata, with stouter 

 more tomentose branches and leaves, broader shorter often coriaceous leaflets, 

 tomentose beneath, and shorter male and female spikes. Male spikes hispid. The 

 leaflet base varies from acute to almost cordate with a rounded lobe on one margin 

 and an acute one on the other. 



4. ZS. Wallichiana, Lindl. in Wall. Cat. 4942; quite glabrous, 

 leaflets 4-6 in. petiolulate subfalcately lanceolate quite entire obtusely 

 acuminate, male spikes panicled, nut globose clothed with golden scales.

Branches and petioles slender. Petiole 3-5 in. ; leaflets thinly coriaceous, bases 

 narrowed into the petiole, opaque on both surfaces. Male spikes in spreading 

 suberect panicles, 3-4 in. long ; flowers clustered, very minute, of 4 unequal oblong 

 segments or bracts ; stamens about 12, irregularly inserted on the segments ; anthers 

 minute, subsessile, didymous. Fern, perianth 4-lobed; ovary globose, stigmas 4 

 sessile spreading. Nut globose, ^ in. diam., crowned with the erect 4 lobes of the 

 perianth; exocarp (tube of perianth) thin, clothed with y ellow- glandular scales ; 

 endocarp thick, bony, intruded base columnar; wings of bract brown, mesial 1-1^' in. 

 long. I suspect that all Roxburgh's description of J. pterococca is taken from this 

 plant, except the nut, which he describes as very hairy and as large as a large pea, 

 which applies to E. spicata, not to Wallichiana. 



5. E. serrata, Plume FL Jav. Jugland. 14, t. 4, and 50?; branch- 

 lets petioles and leaflets beneath glandular, leaflets 4-7 pairs 2-3 in. 

 subsessile coriaceous obliquely elliptic- or ovate-oblong acute or acuminate 

 crenate, fruiting racemes 6-8 in., nut hirsute. Cas. DC. Prodr. xvi. ii. 14.
