 ascending to 5,000 ft. Martaban and Tenasserim, not known from Pegu. A middle- 

 sized or large tree, young shoots often with deciduous hairs. L. coriaceous, lanceolate, 

 blade 6-9, narrowed into pet. J-J in. long, upperside glabrous, underside often clothed 

 with a dense felt of very minute stellate hairs, sec. n. 10-16 pair, i spikes grey- 

 pubescent, in dense terminal panicles, bracts long acuminate, deciduous. 9 spikes

 usually thin, enclosing § or more of the mature nut, scales connate, apex free, tri- 

 angular, acuminate, nut globose, polished, pericarp ^ in. thick. This somewhat 

 variable species merits careful study in the forests. One form with 1. up to 12 in. long

Sect. iv. Cyclobalanus. Male spikes stiff, erect. Bracts of cup connate

Sect. v. Chlamydobalanus and vi. Lithocarjms. Male spikes erect, stiff. 

 Involucre ovoid or globose, enclosing the whole nut, marked on the outside

32. Q. laneeaefolia, Boxb. ; Wight Ic. t. 212.; King Ann. ii. t. 74. Vern. PatU Katus 

 Nep. Subhimalayan tract from Sikkim eastwards, ascends to 5,000 ft. Assam. 

 Khasi hills. Chittagong. Shan hills 5,000 ft. A small evergreen tree, fine med. 

 rays numerous and equidistant, broad rays very few. Branchlets and 1. glabrous, 

 1. pale beneath, lanceolate, blade 5-8, pet. i-f in. Female spikes hairy, involucres 

 mostly solitary. Acorns 5-10, distant on spikes 4-7 in. long, on short thick stalks, 

 involucre thin, enveloping the whole nut, marked outside with 4-6 wavy rings 

 (tuberculate in var. semicristata). Nut silky, obliquely-ovoid. 33. Q. truncata. 

 King Ann. ii. t. 80. Naga hills. Manipiir. Upper Burma, hills east of the 

 Irawadi river 4-6,000 ft. (Maicheng, Shan.) A middle-sized (at times a large) tree, 

 branchlets ribbed, glabrous. ~L. glabrous, thinly coriaceous, pale beneath, lanceolate 

 or elliptic-lanceolate, blade 6-12, narrowed into pet. J-J in. long, sec. n. 10-12 pair, 

 arching. Acorns on spikes up to 6 in. long, in sessile clusters of three, cups confluent. 

 Cups hoary or pubescent, urceolate, almost turbinate, marked in the lower portion 

 with uneven more or less concentric belts, and on the flat truncate top with triangular 

 scales. Nuts entirely included or tips free, ovoid or obovoid, |-1 in. long, the lower 

 three-fourths adhering to involucre, rough, the upper fourth depressed, hoary, not 

 polished, pericarp thin, cotyledons plano-convex. Some acorns from Upper Burma, 

 possibly a new species, have the involucre clothed with flat apjjressed scales, more or less 

 arranged in concentric belts. 34. Q. 011a. Kurz in Journ. As. Soc. Bengal 44. 107 tab.

 with 1 or 2 abortive ones adnate to the base, cup very thick-walled, woody, campanu- 

 late, but narrowed at the mouth, scales broad, appressed, abruptly acuminate, arranged 

 in regular vertical rows. Nut depressed globose, polished, the apex only free. In Fl. 

 Brit. Ind. v. 619 this is supposed to be near Q. truncata. Kurz thought it to be near 

 Q. spicata.
