strong ai-chcd ascending nerves, petiole 1-2 in., fern, panicle erect pyramidal with 

 slender horizontal distant white-tomentose branches, bracts densely tomentose 1-fld.

 Hills, Lister. 



QTJERCUS (Lepidobalauus) SP., Sentfi. in Hook. Ic. PI. t. 1312 (the fruit only). 

 Involucre 1| in. long, broadly ovoid oblong, thickly crustaceous when dry, finely 

 tomentose rounded at both ends, surface with adnate rather distant bracts in broken 

 transverse series longer more crowded and recurved towards the apex ; nut very 

 broadly oblong wholly included adnate all but the very small terminal pubescent area 

 to the walls of the involucre, walls excessively thick and strong, seed conform 

 the cavity, cotyledons fleshy not ruminate. Assam, Jenkins. 



Q. MIXTA, A. DC. Prodr. xvi. ii. 83, consists of imperfect specimens of possibly 

 two species mixed in Wallich's Herbarium (Cat. 2783) with Q. Amnerstiana. 



Q. (Lithocarpus) OLLA, Kvrs in Journ. Seng. As. Soc. 1875, ii. 197, t. 14, f. 9, 

 from Assam, Jenkins. Described from the fruit alone, of which Dr. King has kindly 

 sent me a specimen ; it is broadly pitcher-shaped, f in. high, with a broad flat base 



1 in. diam., and thick walls narrowing to the mouth which is in. diam., sides 

 hoary clothed with many series of appressed broadly triangular cuspidate bracts, 

 mouth thick rounded with the bracts inflexed. Nut with the depressed top level 

 with the mouth of the cup, umbo capitate stipitate. Probably nearest Q. truncata. 



QUEECTJS SP. ? In the Kew collection of drawings of plants of Singapore there 

 are some made by or for a Mr. Parry, and amongst them one represents a magnificent 

 species of oak, with stout branches, elliptic-oblong cuspidate dark -green leaves 12 by 

 5v in., obtuse at both ends or tip cuspidate, with 10 pairs of spreading arched nerves, 

 and a petiole 1 in. ; cups sessile on a short rachis, shallow, broadly campanulate, 



2 in. diam. across the broadly spreading recurved mouth, which is formed of very 

 stout obtuse bracts of an inch long ; nut 1 in. long, broadly oblong, with a rounded 

 umbonate top and deeply intruded base, the walls are represented as very thick ; seed 

 broader than long, vertically grooved, and with a large conical uinbo ; the base only 

 of the nut appears to be embraced by the cup. 



QUEECUS SP., " Antidesmeffi ? Herb. Finlayson, Wall. Cat. 9144," and 



QTJEECFS SP., " Antidesmeae ? Wall. Cat. 9145," Tavoy, are Querci in flower only, 

 and undeterminable.

Habit and character of Quercus, Sect. Chi amydolal anus differs in the 

 closed fruiting involucre enclosing 1-4 nuts and being covered with 

 clusters of spines or tubercles, and often splitting irregularly. Species 

 about 25, one Californian, the rest Eastern Tropical Asian. 



A genus inseparable from Quercus by any constant character; the male and 

 female inflorescences of the two are undistinguishable, except when the fern, 

 involucres contain more than one flower, which is very rare in Quercus. The fruits 

 present internally several very distinct types of structure, but my attempts to 

 ascertain these from dried specimens have failed. The statement under Quercus 

 (p. 601) of my indebtedness to Dr. King for aid in the description of its most 

 difficult species, applies to this equally difficult genus. His forthcoming monograph 

 of the Indo-Malayan species of both genera will be indispensable for their deter- 

 mination. 



A. Involucre ovoid or globose, rarely transversely elongate, dehiscent, 

 spiiious. 



* Walls of involucre more or less concealed by the crowded subulate 

 spines.
