arc of .1 glaucous green, quite glabrous on both sldcii ; on rather long 

 fuotiitalki, ol an oblong oval form, with the indentations generally ter- 

 minating in a bhort bristly spine. The flowers are generally produced 

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

 about fi lines long. This oak is said to be a native of Tortugal. 



Q. calycXna Poir. Diet. Encye. Suppl., 2. p. 216., N. Uu Ham. 7. p. 

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

 ovate-oblong, in a long pubescent calyx. 'I'his oak, according to M. 

 Poiret, greatly resembles the ilex. It is of middling size, with numc. 

 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 &)i^^ r^ 



and shining above, except when quite young; ccttony and rather .^j!*^*^ fc 'il) 

 yellowish beneath, with downy petioles. The acorns are oval, very fei:^ 



yelli 

 long, 



and bc.rue on short, thick, axillary peduncles. The nut is en 



ISIS 



veloped for three quarters of its length in a very deep pubescent calyx, g. Q l\ 

 often S or 9 lines long, covered with very closely set scales, and warty. ^r^<^ ^^ 

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

 the department of Vaucluse, by M. De Bressieux, who sent specimens of it to M. Poiret. 



O. expdnsa Poir. Diet. Encyc. Suppl., 2. p. '217., N. Du Ham., 7. p. 158., has the leaves oval, and 

 slightly denuted; white and cottony beneath : acorns oval on petluucles, with very large, pubescent, 

 bell-shaped calyxe.<. This oak diflers very slightly from 0. calycina, and is a native of the same 

 habitat. It is about lift, 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. „ .. „ , -„ „ ,

 Cycl., No. 37. ; 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 flowers 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 A'ouwfau Du 

 Hanul, it is said to be possibly a variety of /^lex ; but Bosc supposes it to be either closely allied 

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

 the Paris gardens. ^ ^ ,,.„vti^tt

 Clus Hist , I. 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 I ft. high when wild; though 

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

 strongly resemble those of the ilex. They are about 1 in. or IJin. 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. hilmilis of the London gardens, noticed 111 p. 1924., is a very 

 different plant from that here described. 



App. iii. African Oaks 'iSchich have 7wt yet beeJi introdticed. 



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

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

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

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

 closely imbricated ; the upper scales being looser than the others, and somewhat recurved at the 

 point.

very smooth on both sides, deeply 



toothed, somewhat sinuated, decidu- 

 ous. Fruit sessile ; ripening the 



tc.ond year. Calyx tessellated. Nut 



elongated, nearly cylindrical. (.S'«J. 



and nuid.) This oak, according to 



Olivier, seldom attains the height 



of t) It. ; and the stem is crooked, 

 with the habit of a slirub, rather than that of a tree. 'J'he 

 leaves are about 1 in. or IJ in. long, deciduous, bright green, 

 smooth on both sides, but paler beneath ; their serratures are 

 tk-ep and broad, not acutely pointed. Fruit solitr.ry, neatly ses- 

 sile. Cup slightly downy ; its scales not very distinct. Acorn two or three tunes longer than the 

 uip, smooth, nearly cylindrical. Olivier observes that this plant, besides producing the galls ol 

 romincrce, bears a number of different kinds of this excrescence, which are neglected as useless. 

 The tree, acconling to Bosr, has been long in the Jardin des Plantes at Pari-s where it bears the 

 winters quite well in the open air, losing its leaves in the autumn. He has no doubt that it may 

 l>e propagated in abundance in the south of France ; but considers it doubtful whether the insect 

 rx)uld be introduced and multiplied there with equal facility. According to the catalogues, this
