PASANIA. 



This is a widely distributed species, and it therefore presents a number of forms. 

 The following, mostly distinguished by M. De Candolle, may be treated as more or less 

 stable varieties: 



Var. 1. glaberrima, DO. {not of Zoll.) Prod, xvi. ii. 86 (species) ; Blume in Bot 



Verh. ix. 210. t 1 



Male inflorescence glabrous, — Bijdr. 517; Fl. Jav. Cupul. 17. t. 8; Mus. Lugd. Bat. i 

 290; Miq. 1>1. Jungh. i. 10. 



Java and Sumatra. 



Var. 2. brevi-petiolata, DO. he. 



Petiole very short (about '25 in.) ; leaves usually more or less obovate ; the base 



sometimes minutely cordate. 



A common form in the Himalaya and Khasia mountains. 



Var. 3. gracilipes, DC. lc. (excl. syn. Q. turlinata, Roxb.) 



Leaves lanceolate or oblanceolate, gradually narrowed to the petiole, which is some- 

 times 1 in. long; cupules prominently tuberculate; glans not conical. — Miq. in FL Lid. 

 Bat. Suppl. 347 ; Ann. Mus. Lugd. Bat. i. 106. 



Khasia, Burmah, rare; Malayan Peninsula and Archipelago, common. 



Var. 4. depressa, King. 

 Leaves rounded at the base ; ripe glans depressed, semi-globose ; cupule saucer- 



shaped, flat, wide; fruit-spike short. — Q. depressa, Bl. Verh. Bat. ix. 209. t. 2. 



placentaria, Bl. Bijdr. 518; Fl. Jav. Cupul. 19. t. 9; Mus. Bot. i. 291; Miq. in PL 

 Jungh. i. 10; DC. Prod. xvi. ii. 87; Wenzig Jahrb. Bot. Gart. Berl. i. 226.—$. spicata, 



Sm., var. placentaria, Miq. in Ann. Mus. Lugd. Bat. i. 106 ; Fl. Ind. Bat. i. 849. 



De Candolle and Wenzig keep this distinct from Q. spicata, Sm. There are no good 

 specimens bearing this name in the collections at Kew, British Museum, Leiden, Geneva, 

 or Calcutta, and our chief sources of knowledge of the species are Blume's description 

 and coloured figure. And I am unable to see how these latter differ sufficiently from 

 typical Q. spicata as to deserve specific rank. 



Var. 5. microcalyx, DC. I.e.; Blume Mus. Lugd. Bat. i. 290 (species). 



Leaves small; fruit small (under 5 in. in diameter); cupults often solitary or sub- 

 connate; glans usually with conical apex.— Q. microcalyx et anceps, Korth. in Verh. Nat. 

 Gesch. Bot. ^04 and 206; Oudem. Annot. Cupul. Jav. 6. t. iv. fig. 3; DC. Prod. I.e. 86 



(excl. syn. Q. turbinata, Roxb., and Q. Thomsoni, Miq.), Q. Rhioensis, Hance in Joum. 

 Bot. for 1878, 198. 



Khasia Hills common; also in Perak {King's Collector, No. 10947); in Rhio, Java, 

 and Sumatra. 



A very distinct variety; at once recognised by the small size of the leaves and fruit, 

 by the cupules being little connate, and by the glans often having a conical apex.
