The author of this species does not describe the fruit, and his tvpe specimen in tin 

 Leiden Herbarium has none. It was collected in Borneo, from whence, let us hop. 

 better material may some day be forthcoming. At present it is u doubtful species 

 M. De Candolle puts it in Cgclobalanus, while Mi quel (1 c.) suggests that it mav 1> ) a 



Castanopsis. 



Quercus Listeri, King; sp. dub, in Hook. fil. Fl. Br, Iml. v. 61*. 



Young branches minutely pulverulent-tomentose ; tho older with pale, lenticellate 

 bark. Leaves coriaceous, elliptic-oblong, acuminate, entire; tho ba*o acute ; u pp < • r sur 



glabrous, shining; the lower paler, very minutely tomentose; main n rves 9 to 1 pairs, 

 rather prominent below; length of blade 10 to 14 in., breadth 4 to in.; petio 5 1*8 in 

 to 2 in. Male jloivers in erect, narrow, pale, tomentose, axillary and terminal panicles 

 shorter than the leaves. Female spikes solitary, axillary, shorter than the leaves; flown 



in glomeruli of 3; the involucres with many, rather narrow, tubercles; stylos shor- 



ted. Ripe fruit unknown. Quercus Jenkinsii, Benth. in Hook. Ic. H. as regards t. 

 2313 only.

The acorn of this is unknown, and I would not have described the species but for 

 the fact that the leaves and male inflorescence, as characterised above, were figured by 

 the late Mr. Benthani (Hooker's Icones t. 1313) as part of tho materials on which lie 



founded his species Q. Jenkinsii. On carefully examining them, I am driven to tit 



conclusion that these materials do not all belong to the tame plant. They consist of 

 three sets of things— (1) Griffith's Assam specimens with leaves and male inflorescence 

 (Sudya and Nanmoo, No. 4464, and Mishmi, No. 4472, Kew Dittrib); (2) Griffith's 

 Burmese specimens (banks of Mogoung, No. 4460, and Lannme, No. 4469, with perhaps 

 the Wallichian sheet 9145). These have leaves and spikes with young fruit. The leave 

 taper much less and have shorter petioles than the former set; (3) loose acorns in a 

 bottle, bearing on a label in Griffith's handwriting the words " Casta nea, No. 122, Major 

 Jenkins, October 18J3." The first and second of these do not, in my opinion, belong 

 to one, but to two species. The loose acorns may belong to either of these two, or 

 to a third of which no other parts have yet been collected. Mr. Benthani published 

 the Icones Flantarum two figures of Q. Jenkinsii, viz. Ic. 1313, on which the A 



(male) plant is figured (and it is for this which I now propose the name Q. Often) ; 

 and Ic. 1312, on which the Burmese (female) plant is figured, together with two of 

 Jenkins's loose acorns. For the latter the name Q. Jenkins , Benth., may he retained ; but 

 pending the receipt of fuller sets of specimens, the species must, I think, be considered 



a doubtful one. , , , 



The female spike, which I now figure and describe as that of Q. Listen, was collected 



by Sir D. Brandis in Assam. The leaves attached to the spike are quite the same as 



those of Griffith's No*. 4464 and 4472 ; but the spike differs from that figured by 



Mr. Bentham for Q. Jenkinsii, inasmuch as the latter shows the flowers as solitary.
