Plate 56 B. — Q. bancana, Scheff. 4, leaf; 5, spike with ripe acorns; 6 cupule, seen 

 from above; 7, glans, side view,— all of natural 



50. Quercus Reinwardtii, Korth. in Verh. Nat. Cesck. Bot. 211. 



Young parts minutely lepidote-canescent. Leaves coriaceous, oblong-lanceolate, bluntly 

 acuminate, entire; the base acuminate; upper surface glabtons shining, the n 

 obscure, the midrib distinct; under surface paler, dull, minutely canescent, the midrib 

 thick and prominent; main nerves 7 to 10 pairs, sub-glabrous, and dark coloured, as ere 



the secondary and minor nerves; length of blade 3 •'» in. ko 5 in., breadth 1*4 in. to 1 



in. ; petiole '25 in. to '4 in. Male spikes shorter than the leaves, solitary, axillar; 

 pubescent; the flowers interruptedly glomerulate. Female sp%k*% longer than the leaves, 

 terminal or axillary. Cupules minutely sericeous, solitary, on long stout peduncles; when 

 young sub-globular, enveloping the whole of the young plans except its apex; when 

 adult shallow, campanulate (or even saucer-shaped when very old), narrowing at de- 

 base into the thick annulated peduncle ; lamellae about 7, the lowest the broadest ; their 

 edges entire (the scales being completely unit. I), 1 in. in diameter and -25 in. deep. 

 Glans hemispheric, apiculate, minutely but deciduously pubescent; (immature) -9 in. in 

 diameter and *5 in. long.— Blume Mus. Lugd. Bat. i. 300; Miq. Fl. Ltd. Bat. i. 1, - > ; Ann.

Sumatra— Korthals (312); Borneo,— Teysmann (Herb. Uort. Bot. Bogor. 11301 and 11300). 



Of this species there are very few examples in collections. The leaves of Korthals' 

 and Miquel's specimens in the collections at Leiden and Utrecht have from 10 to U 

 pairs of nerves, while Teysmann's Bornean specimens have only 7 to 8 pairs. Moreover 

 the secondary nerves of the Sumatra specimens are nearly as large and distinct as the 

 primary nerves ; and the reticulations are also prominent, which is not the case in th< 

 Bornean plants. Nevertheless, I think the two sets are referable to one speci. Kartbali 

 specimens have no ripe fruit, and the fruit of Teysmann's appears to be scarcely ripe 

 But, as far as the materials go, the two sets agree in fruit.

51. Quercus sericea, Scheff. Observ. Bhtjtol ii. 49. 



Younc branches minutely puberulous, sparsely lenticellate. Leaves on rather long 

 slender petioles, coriaceous, narrowly elliptic-lanceolate (sometimes oblique), acum.nate, 

 entire- the base acute or acuminate (sometimes unequal); the upper surface shining; the 

 lower paler and less shining, both glabrous; nerves 8 to 10 pairs and, like the midrib 

 prominent below; length of blade 35 in. to 6 in., breadth 1-2 in. to 1-8 in.; petiole '4 

 in to -7 in. Acorns in short axillary spikes, sessile, solitary. Cupules (young) sub- 

 turbinate, with 5 or 6 denticulate zones, sericeous. Glans ovoid-globose ; the apex 

 depressed and abruptly apiculate, densely
