 black.

Onciclium continued. 



Grenada. A distinct variety, growing about 1ft. high, and pro- 

 ducing flower-spikes 2ft. in length, upon which are borne its 

 beautiful flowers. [C.] 



O. O. nubigenum (cloud-born), fl., sepals and petals brownish, 

 with a crimson or nearly crimson hue, or striped with crimson 

 lines ; lip very variable, but generally white, yellow at the base, 

 marked with violet or purple. Andes, 1867. SYN. 0. Denisoni-

Other varieties are : Dayanum, white, purple ; Phalcenopgis,

pliflh-brown colour, with a bent forward anterior part, and many 

 toothlets on the posterior side ; the claw whitish flesh-colour, 

 and the border sulphur-yellow ; wings purplish-brown, with two 

 swordblade -like laminae under the stigmatic hollow ; spike many- 

 flowered. Spring. Peru, 1870. A rare species, having flowers 

 as large as those of 0. serratum. (B. M. 5858.) 

 O. cucullatum (hooded).* /. usually purplish-brown, with a 

 large lip, which is rosy-lilac or rosy-purple, spotted with deep 

 purple ; spike slender, erect, bearing from three to six or more 

 beautiful blossoms. I. solitary, linear-oblong, acute. Pseudo- 

 bulbs small, oblong. Peru, New Grenada, &c. This very variable, 

 dwarf species may be grown either upon a block of wood or in a 

 pot ; it must never be dried off, but kept slightly moist all the 

 year round, when it will prove almost a perpetual blossomer. 

 (L. & P. F. G. 87.) There are a number of varieties of this 

 species ; all are handsome, and last a long time in full 

 beauty. [C.] 



O. C. flavidum (yellowish), fl., sepals and petals yellow, blotched 

 with brown ; lip purple, margined with white. Spring. New 

 Grenada. Similar in habit to the type, and most desirable. [C.] 



O. o. glganteum (giant). This is simply a fine variety, differing 

 from the type onlyin its larger flowers and more robust habit. [C.] 



O. O. macrochilum (large-lipped).* fl., sepals and petals rich 

 plum and crimson ; lip mauve, spotted with dark violet. New 



O. decipiens (deceptive). /. yellow ; upper sepals obtuse, lateral 

 ones acute ; petals obtuse, undulated, larger ; lateral lobes of lip 

 small, almost round, unguiculate; middle lobe much larger, 

 bilobed ; scape simple, usually one-flowered. I. ensiform, shortly 

 equitant. A. 3in. Mexico, &c., 1835. (B. B. 1911, under name of 

 0. iridifolium.) 



O. deltoideum (triangular). /. yellow, arranged in a large, stiff, 

 compact panicle ; sepals and petals whole-coloured ; crest of the 

 lip reaching more than half-way from the base to the point, 

 consisting of numerous straggling warts and teeth. Peru, 1836. 

 (B. R. 2006.) 



O. Denisonianum (Denison's). A synonym of 0. cucullatum 

 nubigenum. 



O. dladema (diadem).* fl. about 100 to a stem ; sepals and petals 

 shining chocolate-brown ; lip fine yellow ; the extremities of the 

 petals, joined together above the column, present the aspect of a 

 diadem (whence the specific name) ; flower-stem 2ft. to 3ft. high, 

 branched. Pseudo-bulbs large. Cool region of equatorial 

 America, 1866. [C.] 



O. dladema (diadem), of gardens. A synonym of 0. serratum. 



O. dimorphum (two-formed). /. yellow, spotted with brown, 

 paniculate ; lip sometimes three-lobed, and sometimes almost 

 entire. I. oblong-lanceolate, bluntish. Pseudo-bulbs oblong, 

 compressed. Brazil, 1870. (E. G. 637, Figs. 4-6.)
