LITHO CARPUS. 



paler, dull, glaucescent; the midrib prominent on both surfaces; the 9 to 12 pairs of 

 nerves distinct only on the lower; length of blade 4 to 6 in., breadth 1*65 in. 

 to 1 '85 in. ; petiole *3 in. to % 6 in. Male spikes longer than the leaves, solitary 

 and axillary, or in lax few-branched terminal panicles, minutely puberulous. 



Female spikes single, solitary. Male flowers in glomeruli of 3, each glomerulus subtended 



• a long linear bracteole; perianth 6-dentate; stamens 12. Cupules shallow, solitary, on 

 stout, annulate peduncles ; at first depressed-turbinate, wider than the glans ; when adult, 

 turbinate-hemispheric ; the edge incurved, minutely tomentellate ; the lamellae about 8, 

 or as few as 4, bold, the lower wide and slightly oblique, the upper approximate and 

 concentric, the edges of all entire. Glans depressed-spheroidal or patelliform, enveloped 

 by the closely- applied cupule, except on the broad, flat, and truncate or convex, 



glabrous, shining apex; 1 to 1*5 in in diameter and 75 in long. — Blume Fl. Javan. Cupul

This is rather variable as to the shape of its fruit. Both the typical form and that 



which was named Q. convexa by Blume occur in Java and Sumatra. In Perak only th 

 latter has yet been found. The leaves of this species are very like those of platycarpa 

 and of JFenzigiana, but the fruit of the latter is very different.

76. Quercus Maingayii, Benth. in Hook. Ic. Plant 1314. 



Young branches and inflorescence minutely fulvous-tomentose. Leaves coriaceous, 

 ovate-lanceolate, shortly acuminate, entire; the base acute; upper surface glabrescent; 

 the midrib and nerves on both surfaces minutely lepidote- pubescent ; under surface 

 covered with very minute, pale, stellate, pubescence; main nerves 15 to 18 pairs, bold 

 and prominent on the under surface; length of blade 8 to 10 in., breadth 3 to 4 in.; 

 petiole about 1 in., stout, minutely tomentose. Female spikes solitary, axillary, shorter 

 than the leaves; the rachis puberulous; flowers solitary, sessile. Ripe acorns on short 

 thick peduncles, narrowly pyriform, with truncate umbonate apex. The cupule woody, 

 about -2 in. thick, closely enveloping the whole glans except its styles, and for the most 

 part adherent to the glans, indehiscent, externally minutely tomentose, with about 3 

 obscure, wavy, oblique lamellae; length about 1*5 in.; breadth -8 in., peduncle less 

 than 5 in., very thick.— Hook fit Fl. Br. Ind. v. 617.

Mr. Bentham describes the flat umbonate apex of the cupule as dehiscing in a 

 circumscissile manner; but I have seen no specimen showing any appearance of 



dehiscence. Dr. Wenzig considers this species to be reducible to Q. Javensis, Miq 



but, although resembling that in its acorn, this differs toto ccelo from it in its leaves.
