C. PURPURATUM, Lindloy. — A pretty stemless species, witli beautifully 

 tessellated oblong acute foliage, and producing its flowers during the winter 

 months. The flowers are large, very much in the way of those of C harbaiv/m, 

 but differ in the broad oval-oblong acute, ciliated, not verrucose petals, which 

 are brownish-purple streaked with deeper lines and closely dotted at the base 

 with dark purple ; the dorsal sepal, which has more pure white at the end, is 

 acuminate, with revolute edges, and is boldly striped with purple on a white 

 ground. Sir W. J. Hooker thinks Dr. Wight's figure quoted below rather 

 belongs to 0. harbatwm.— Malay Archipelago.

C. PYCNOPTERUM, iJcJift. /.—A hybrid the origin of which is not known. 

 " This is a very interesting plant, of surprising colour ; it has the leaf of 

 G. hirsutissimum, and a two-flowered peduncle, much in the way of that of 

 C. Lowii, but smaller and apparently very much shorter, brownish, densely 

 covered with short hairs ; the triangular ancipitous bracts are green, with a 

 few dark longitudinal stripes ; both sepals are of a light striking parrot-green, 

 the upper one is broader, the inferior one narrower and cucuUate ; the ligulate 

 petals are broader towards their acute apex, a good deal longer than the 

 sepals, and ciliate ; at the base they are green, with dark warty blotches, and 

 excepting this they are of a violet colour, turning into what we call, since 

 Dr. Lindley in Orchidology, port-wine colour ; the lip has that peculiar hue 

 between olive-green and brown" (H. G. Eeichenbach, in Gardeners' Chronicle, 

 N.S., 1876, V. p. 622). — Garden hybrid. 



C. PYCNOPTERUM PORPHYROSPILUM, Veitch.—We are not acquainted 

 with this hybrid, but Messrs. J. Veilch & Sons, in whose nurseries this 

 hybrid was raised, give the following description in their Mamial of Orchida- 

 ceous Plants : — " Flowers larger ; sepals whitish, with green veins ; petals more 

 brightly coloured ; infolded lobes of lip yellowish, with a few brownish warts." — 

 Garden hybrid. 



Stn. — C. porphyrospiliim. 



C. RADIOSUM, jRchb. /.—A cross between C. Laii-renceanum and C Spicer- 

 ianum, which is described by the late Professor Eeichenbach as follows : — 

 " The dorsal sepal is remarkable — la piece de resistance of the whole, though 

 neither so striking as in G. Spicerianwm, nor as in G. Lawrenceaniim. It is 

 rather broad and acuminate, white, with mauve-purple lines over the chief 

 nerves (a dozen), it has a dark purple, almost concealed mid-rib ; all these 

 nerves are green at the base, and have a green tint between them ; dorsal 

 sepal nearly as long as the lip, with light brown lines ; petals nearly divaricate, 

 though descending a little, a little undulate at the margin, and provided there 

 with some ciliae, green with sepia-brown mid-line, a wash of sepia-brown around 

 the anterior borders, and numerous sepia-brown spots on the upper margin ; 

 the form of the lip is that of G. Lawrenceanum, green on the back, brown with 

 green border in front ; staminoie nearly as in G. Latorenceanum, though only 

 with three teeth in front, but with a light mauve disk and a white border. The 

 orange eye of G. Spicerianum has vanished" {Gardenera Ghronicle, n.s., 1885 

 xxiv. p. 424). — Garden hybrid.
