CYCLOBALAKUS. 



.specimens of it were absent from all the great European collections until the distribution 

 from Kew of Maingay's plants. M. De Candolle (not having seen a specimen) suggests 



in the Prodromus the identity of this with Q. lancecefolia, Roxb., which, however, it does 

 not really resemble. On his unpublished figure Roxburgh has written the name cuneata as 

 an alternative to lucida, and Wallich adopted the former in his Catalogue as above noted. 



The nearest ally of this is Q. omalkos, Korth. 



Plate 64 — Q. lucida, Roxb. 1, branch with male flower- spikes ; 2, female flower- 



spikes; 3, spike of cupules, half ripe; 4, ripe acorn; 5, branch of a small-leaved form 

 6, ripe fruit of the same, — all of natural size; 7, part of spike of male flowers: enlarged. 



62. Quercus omalkos, Korth. in Verh. Nat. Gesch. Bot. 214. 



All parts (the inflorescence excepted) glabrous. Leaves thinly 



ilat 



or oblanceolate, entire ; the apex blunt (rarely shortly cuspidate) ; both surfaces quite 

 glabrous and shining; nerves 10 to 14 pairs, slightly prominent on both surfaces; the 

 reticulations distinct on the lower, and the midrib strong ; length of blade 2 to 4 in., 

 breadth 1 to 1*5 in.; petiole '2 in. Spikes longer than the leaves, male or androgynous, 

 slender, puberulous, solitary and axillary, or forming sparse, few-branched, terminal 

 panicles. Ripe cupules solitary, sessile, saucer-shaped, thick-walled, with incurved lip ; 

 lamellae 8 to 10, the lower broadest, minutely tomentose ; their edges undulate, sub-entire, 



1 in. to 1*25 in. in diameter and about *25 in. deep. Pipe glans depressed-hemisph 



apiculate ; the base truncate, smooth, shining, -7 in. to *9 in. in diameter and about *6 

 in. long. — Hook. fl. Fl. Br. Ind. v. 614 ; Blume Mus. Lugd. Bat. i. 301 ; Miq. Fl. Ind. Bat. i.

Sumatra, — Kcrthals ; Perak, — Scortechini (King's Collector, Nos. 5950, 6901, 8447, 8194) ; 

 at elevations of from 500 to 3,000 feet. 



A handsome tree, 50 to 100 feet in height, not uncommon in Perak. This is nearly 

 allied to Q. lucida, Roxb., but the leaves of this are smaller, thinner in texture, and with 

 much more distinct nervation. Moreover, they dry of a pale olive-green colour, while those 

 of lucida dry of a deep brown.

 of ripeness; 9, cupule, seen from above, — of natural size. 





63. Quercus platycarpa, Bl. Fl. Javan. Cupulif 27. t. 15. 



Young branches pale, lenticellate, glabrous. Leaves coriaceous, elliptic or sub-obovate- 

 elliptic, entire, shortly and abruptly cuspidate ; the base rounded or acute ; upper surface 

 glabrous and shining, lower dull, covered with a layer of minute, pale, lepidote pubescence ; 

 nerves 9 to 10 pairs, thin, slightly prominent; length of blade 4 to 6 in., breadth 2*25 

 to 2*8 in. ; petiole *5 in. Spikes androgynous, puberulous, in small, terminal, and axillary 

 panicles; the female flowers few. Male flowers solitary or sub-glomerulate. Ripe cupules 

 on a slender lenticellate puberulous rachis, shortly pedunculate, solitary by abortion, 

 saucer-shaped, puberulous, embracing the lower third of the glans, 1*5 in. in diameter and 

 2 in. deep ; the lamellae about 5, rather prominent, entire, sharp-edged. Glans depressed-
