pollon-massos in their place. Those are two, with deep indentatinns, attaclied hy a 

 broiid sliprs to a transverse somewhat triaua;ular gland. Old bulbs leafless, now 

 undeveloped bnlbs leafy. Leaves broad, plicate, sbeathins; at the base. Scape from 

 the base of the young; leafy bulb, shorter than the leaves. Flowers in curved, 

 drooping, rather dense racemes. Species 3 or 4. 



Ci'MBiDirir, Sir. 



{Eu-Ci/mbidinm, of Lindley). 



Epiphytes with or without bulbous bases. Stems tufted. Roots few, fleshy. 

 Leaves long, narrow, expanded at the base, and these alternately aud closely 

 overlapping one another, so as to form a sort of false stem. Flower-stalk of varying 

 length, proceeding from the axils of the lower leaves, few- or uiany-flowered. Sepals 

 and petals nearly equal, spreading. Lij) 3-lobed or undivided, free, articulated with 

 the column, concave, without a spur. Column prominent, erect, half-round. Anther 

 2-celled. Pollen-masses 2, bilobed behind, sessile on a largo triangular gland. 

 Flowers generally handsome, in short few-flowered erect, or in many-flowered pen- 

 dulous racemes. Species 4. 



C. ALOIFOLIUII. 



A common plant, at least in the Tenasserim Provinces, with long, narrow, hard, 

 rigid, fleshy or leathery leaves, and a long ckooping raceme of dull-coloured flowers. 

 It ibrms large masses on trees. 



C. TIGKINUII. 



A small mountain species, about 8 inches high, tufted. Loaves 3 or 4, from the 

 top of the j'oung pseudo-bulbs, which are enveloped in tlieir sheathing bases. Scape 

 radical, scaly below, bearing from 3-G, rather large flowers, two inches across. 

 Sepals and petals oblong, of a uniform yellowish-green colour, stippled with red at 

 their base, wide-sproading. The u])per sepal and the petals nearly erect ; the lati^ral 

 sepals distant, spreading. Lip 3-lobed, brt>ail but tapering below. Side lobes rounded, 

 streaked with red on the inside ; middle lobe oblong, pointed, creamj'-white, with 

 transverse bars and blotches of red. There are two raised ridges at the back of the 

 lip. Column curved forwards, green. Pollen-masses 2, lengthened transversely, 2- 

 lobed, sessile on a triangular gland. 



An interesting peculiarity of this species is the dimorphism of its flowers, 

 observed by nie on a large number of plants, on the top of Moolee-it, where it is 

 abundant at about 6000 feet. There are two kinds of flower on the same stem. Out 

 of about 6 flowers, the terminal ones are normal, as described, and perfect in 

 structure. But the lower flowers arc different. They are of a rich red colour 

 throughout, and rather blotched than striped, and theii' structure is imperfect. The 

 column is quite abnormal, being unusually thickened, and less curved. There is no 

 anther at all, and there are no pollen-masses ; but the edges of the column at the top 

 are turned inwards so as to form a sort of hood, and underneath these edges is a snudl 

 quantity of a yellow waxy substance (pollen) in an amor|)bous state. And, occa- 

 sionally, the intermediate flowers are intermediate also in condition, having no anther, 

 but perfect pollen-masses, though without any triangular gland. 



C. Lowi.ixrji. 



A very handsome .species. Stems tufted, pseudo-bulbs ; or rather the swollen 

 bases, covered witli tlie sheathing leaves, which are very long and narrow, 2-3 feet, 

 and only about an inch broad. Scape 2-3 feet long, drooping. Flowers 12 or more, 

 3-4 inches across. Sei)als and petals green, striped witli red. Lip 3-lobcd ; lateral 

 lobes large, green ; middle lobe witli 2 ridges at tlu^ back, white in the centre, with a 

 lovely niaroon-eolourcd tip. Column green, with red markings. Presumably collected 

 in Upper Burma, by Boxall, and sent to 'Sir. Low. I had a plant from the same 

 quarter, which 1 at first took for C. (jicjanUum till 1 saw the flowers. 



C. Pauishii. 



Stems tufted, not bulbous. Leaves 2-rauked, long, linear, 18 inches by 1,
