along each side. Capsule., wings rounded, subequal. Stigmas pale yel- 

 low, revolute, angled, pubescent along the edge. 

 This species flowered at the Royal Botanic Garden, Edinburgh, in April 

 1828, having been raised in 1826 from seed sent by Dr Johnston from 

 Bombay. Like all the other species, it requires the heat of the stove. 



Begonia papillosa. 



B. papulosa ; caule rotundato, erecto ; foliis insequaliter cordatis, acumi- 

 natis, inaequaliter dentato-ciliatis, supra albo maculatis, papillisque 

 acuminatis raris, infra ad venas pubescentibus ; stipulis ovatis, acu- 

 minatis, integerrimis ; capsulse alis subsequalibus, obtusangulis. 



Description — Stem erect, 14 inches high, scarcely branched in our spe- 

 cimens till after being cut down, but probably more when in a vigo- 

 rous state, somewhat tumid at the joints, round, brown. Petioles alter- 

 nate, spreading, round, channelled above, pubescent, 1^ inch long. 

 Leaves three and a half times as long as the petiole, very unequally cor- 

 date, acuminate, somewhat undulate and bullate, crisped, on the upper 

 surface bright green and shining, occasionally spotted with white, and 

 having distant papillae, of which each is terminated with a curved, ra- 

 ther harsh hair, red and glabrous below, except at the veins, which are 

 sparingly pubescent, unequally tooth-ciliated, and somewhat angled. 

 StipvlcB ovate, acuminate, smooth, entire, marcescent. Cymes axilfery, 

 longer than the leaves, turned to one side of the stem, drooping, (thrice ?) 

 dichotomous, peduncles and pedicels flattened. Bracteee opposite, ovate, 

 coloured, deciduous, placed in pairs at each division of the cyme, and at 

 the base of each female flower, but awanting in the males. Male flowers 

 placed in the angle of the bifurcations, and, as it would appear, always 

 along with a female at the ultimate divisions of the cyme, where they 

 hang on the outside of the female flowers in the two lateral, and on the 

 inside in the two middle divisions of the cyme, each always expands be- 

 fore the corresponding female flower ; this distribution and premature 

 evolution of the male flowers are common in the genus. Corolla tetrapeta- 

 lous, very unequal, large, rather more so in the female flowers, where the 

 external petals are retuse, fully three quarters of an inch broad by half 

 an inch long ; in the male cordato-subrotund. Stamens numerous ; fila- 

 ments slender ; anthers large, wedge-shaped. Pistils yellow, somewhat 

 spreading ; styles channelled, enlarging upwards ; stigmata large, lobed, 

 revolute, crisped and pubescent ; germen nearly equally winged, angles 

 blunt, and upper edges at right angles to the axis of the flower. 



This species flowered in the stove of the Royal Botanic Garden, Edin- 

 burgh, in April this season, and about the same time in the three last 

 years. We received the plant from Kew in 1824, but without specific 

 name, or an intimation regarding its native country. 



Cattleya intermedia. 



C. intermedia ; perianthio subsequali, subacuto ; lobello trilobo, lobo medio 

 cordato rotimdato ; spatha obtusa, subherbacea, lata, compressa, pedun- 

 culum subaequanti ; caule articulato, clavato, vix bulboso, compresso. 



Description Plant parasitical. Root of strong, cylindrical, branching, 



fibres, green where exposed. Stems numerous, jointed, 3-9 inches high, 

 enlarging upwards, but scarcely bulbous, smooth when in vigour, but 

 often deeply furrowed, covered with grey, withered, blunt, ad pressed 

 sheaths, green where exposed, terminated by two leaves. Leaves 5 inches 

 long, sub-opposite, nearly equal, spreading, flat, ovato-ligulate, fleshy, 

 nerveless, very slightly notched, and mucronate at the apex, yellowish- 

 green when young, afterwards darker. Spathe submembranous, blunt, 

 compressed, broad, green, united at its edges, open only at its extre- 

 mity, 2 inches long. Peduncle scarcely exserted, round, smooth, sup- 

 porting at its apex one flower in our specimens, but as there is also an 

 abortive bud, it seems probable that the natural inflorescence is 2-flower- 

 ed. Perianth nearly equal, of uniform, delicate, faint lilac colour, ino- 

 dorous ; upper segment 2\ inches long, linear-elliptical, reflexed on the 

 edges, and terminated by a greenish point, the four others 2 inches long,
