CYCLOBALANTTS. 



Spikes androgynous, in small axillary or terminal panicles shorter than the leaves. Male 

 mers 6-toothed, with 12 stamens and conspicuous pubescent rudimentary ovary. Ripe 

 pules 1*5 to 2'25 in. in diameter, -6 to *8 in. deep, solitary, sessile, shallow, campa- 



nulate, covering only half the glans, very thick -walled (-25 in. thick) ; lamellae about 



10, rather bold, minutely tomentose, with irregular, undulate, glabrous edges. Glans 



patelliform; the apex sub-depressed, umbonate, 1*25 to 1*5 in. in diameter and -5 in.

A magnificent tree, often attaining a height of 150 feet. Owing to the difficulty of 

 obtaining its leaves and flowers, this species has been three times named from its acorns 



(picked up under trees), and until now its leaves have not been described. 

 Roxburgh's original name of depressa must unfortunately give way, as Humboldt had 

 previously appropriated it for a South American species, and this circumstance having 

 been observed by Endlicher, he rechristened it cycl&phora, without, however, describing 

 it. In the Calcutta Herbarium Roxburgh left a coloured drawing of the acorn, which 

 makes the identification of his depressa a matter of absolute certainty. Wallich issued 

 good specimens of this as placentaria, Bl., but a reference to the latter's published figure 

 (Fl Jav. Cup. t 9) shows that his placentaria is really one of the forms of the Protean 



. spicata, Sm. Miquel suggests that Q. cyclophora is allied to rotundata, Bl., but the 

 suggestion is disposed of by an inspection of Blume's figure of the latter species 



t 11).

Young shoots pale, glabrescent. Leaves thinly coriaceous, oblong-lanceolate, acumi- 



nate; the edges entire, slightly recurved when dry; the base acuminate; both surfaces 

 dull, covered with very minute whitish pubescence, sub-glaucescent ; nerves 8 to 9 pairs, 

 much curved, ascending obliquely, prominent beneath; length of blade 7 to 11 in.. 

 breadth 1*75 to 3 in. ; petiole *3 to *5 in. Spikes longer than the leaves, axillary, or in 

 few-branched terminal panicles; the female spikes nearly as numerous as the male. 

 Male perianth deeply 6-cleft; stamens 12; rudimentary ovary rather small, sericeous. 

 Cupules sessile, solitary, depressed-globular when young and enveloping the whole of 

 the dans except its apex ; when ripe, saucer-shaped or even discoid, wider than the 



glans and embracing only the lower half of it, remotely and minutely denticulate, 

 griseous-puberulous, from *9 in. to 1-3 in. in diameter, and -25 to '35 in. deep; lamellae 

 about 6, broad. Glans (globose-conic when young) depressed-turbinate when ripe, and 



rowned by the short thick column of styles, minutely pubescent, *8 in. to 1 in. in 

 diameter, and about *5 in. long. — Hook. fil. Fl. Br. Ind. v. 615.
