ARBORETUM AND FRUTICETUM. 



PART III. 



are off ■ glaucous green, quite glabrous on both sides ; on rather long 

 footstalks, of an oblong o\.il form, with the indentations generally ter- 

 minating in a short bristly spine. The Mowers are generally produced 

 two or three together at the extremity of the branches, on a peduncle 

 about 6 lines long. This oak is said to be a native of Portugal.

 159 ■ has oval-elliptic leaves, cottony and yellowish beneath. Nuts 

 o\ ate-oblong, in a long pubescent calyx. This oak, according to M. 

 Potest, greatly resembles the ilex. It' is of middling size, with mime. 

 rous unequal branches, covered, when young, with an ash-coloured 

 down The leaves are oval, and slightly pointed at the apex ; about 

 1 in. long, entire, or slightly dentated with a few small teeth ; smooth 

 and shining above, except when quite young; cottony and rather 



?ellowish beneath, with downy petioles. The acorns are oval, very 

 ong. and borne on short, thick, axillary peduncles. The nut is en- 

 veloped for three quarters of its length in a very deep pubescent calyx, 

 often S or lines long, covered with very closely set scales, and warty. 



ISIS 



This tree is a native of France, having been found near Orange, in 



the department of Yaucluse, by M. l)e Bressieux, who sent specimens of it to M. Poiret. 



O. easMbtSfl Poir. Diet Encyc. SuppL, 2. p. 217., N. Du Ham., 7. p. 158., has the leaves oval, and 

 slightly dentated ; white and cottony beneath ; acorns oval on peduncles, with very large, pubescent, 

 bell-shaped calyxes. This oak differs very slightly from Q. calycina, and is a native of the same 

 habitat. It i> about IS ft or 15 ft. high ; dividing into numerous branches, which are downy when 

 young. Its leaves closely resemble those of Q. calycina,' except in being rather shorter, and that 

 their downy pubescence beneath is white, instead of being yellowish. The acorns are shorter, and 

 thick; and the calyx is nearly flat, and bell-shaped. Poiret mentions two forms of this species 

 differing slightly in the calyx. 



y. rotundifolia Lam. Diet, 1. p. 723., Willd. Sp. PI., 4. p. 434., N. Du Ham., 7. p. 158., Rees's 

 CycL, No. '31. ; the round-leaved Spanish Oak; Chene a Feuilles rondes; has persistent leaves, which 

 are obovate-oblong, with spinous teeth, heart-shaped at the base, smoothish above, and downy 

 beneath. This oak is very imperfectly known, as neither Lamarck nor Willdenow had seen either 

 its dowers or fruit. The acorns are said to be sweet and eatable. It is a native of Spain, whence it 

 was brought to France; and there is a small plant in the Jardin des Plantes. In the Nouveau Du 

 Hannl, it is said to be possibly a variety of /Mex ; but Bosc supposes it to be either closely allied 

 to, or identical with, Q. gramuntia. There are numerous plants of it, he says (writing in 1806), in 

 the Paris gardens.

 C'/us. Hist., 1. p. 19. ; the dwarf Portuguese Oak ; Chene pygmee, Fr.; has the leaves obovate, with 

 spiny teeth at their apex, and rather heart-shaped at the base; downy beneath. Calyx of the fruit 

 flattened. Nut oblong. This curious little shrub was found by Clusius, in barren sandy ground near 

 Lisbon, very abundant. The whole plant is rarely more than 1ft high when wild; though 

 Lamarck says that, by cultivation, it may be made to attain the height of 3 ft. or 4 ft The leaves 

 strongly resemble those of the ilex. They are about 1 in. or l£in. long, on very short footstalks; 

 smooth and shining above, downy and hoary beneath ; the larger veins straight and parallel, and 

 the smaller ones reticulated. The acorns are sessile; the nut is oblong, and more bitter than that 

 of the common British oak, with a very shallow, and rather flattened, calyx. This is still common 

 in sandy soil in Portugal. The Q. humilis of the London gardens, noticed in p. 1921., is a very 

 different plant from that here described. 



App. iii. African Oaks which have not yet been introduced. 



Q. obtecta Poir. Diet Encyc. Suppl., 2. p. 218., N. Du Ham., 7. p. 163., has the leaves nearly oval, 

 slightly toothed, glabrous, shining. Acorns on peduncles, nearly solitary. Nut hidden in the cup. 

 The branches of this species are ash-coloured, glabrous, and extremely flexible. The leaves are 

 entire, or bordered with a few spiny teeth. The cup only opens a little at the extremity, and is 

 dose!* imbricated; the upper scales being looser than the others, and somewhat recurved at the 

 point. 



App. iv. Oaks of Asia Minor and Persia not yet introduced.

Olivier, seldom attains the height

commerce, bean a number of different kinds of this excrescence, which are neglected as useless.
