and very distinct species, of compact, dwarf-growing habit. 

 (B. M. 3912; B. R. 1840, 10.) [C.] 



O. o. albiflorum (white-flowered).* A valuable acquisition as a 

 winter blossomer, having snow-white flowers. It is, however, 

 very rare. Guatemala, 1873. Sometimes known as O. o. album. 

 (F. M. 398.) [C.J 



O. pachyphyllum (thick-leaved). A synonym of 0. Cavendishi- 

 anum. 



O. Papilio.* Butterfly Plant fl. pale golden-yellow, barred with 

 chestnut-brown, usually solitary and terminal on the spike, some- 

 what resembling a large butterfly in shape ; sepals long, narrow, 

 erect, bearing a fanciful resemblance to the antennae and pro- 

 boscis of a butterfly ; petals extending horizontally to form the 

 wings, and the lip representing the body. I. deep olive-green, 

 beautifully streaked and spotted with reddish-brown. Pseudo- 

 bulbs somewhat compressed, one-leaved. Trinidad, 1823. A 

 remarkable and beautiful plant. It succeeds best upon a large 

 block of wood, and with good exposure to sun and light The 

 flowers are often 2in. across. The old spikes should not be 

 cut off, as new buds are continually developed at the apex 

 See Fig. 731. (B. M. 2795; B. R. 910.) [T.] There are some 

 striking varieties of this species, of which the following are 

 noteworthy :

 (I. H. 500.)

 low, with a profusion of irregularly'disposed, bright brown 

 spots and blotches ; the margins of the lip and lateral 

 sepals beautifully undulated and crisped; spike long, con- 

 tracted at intervals, forming knotty joints, one-flowered. 

 I. solitary, large, coriaceous, beautifully spotted with 

 crimson and red, upon a dark ground. Pseudo-bulbs 

 cylindrical, deep brown. Central America, 1823. A very 

 beautiful plant. (R. X. O. 33.) [T.] 



O. P. limbatum (bordered), fl. clear yellow, with 

 distinct cinnamon-brown blotches, and a broad, unin- 

 terrupted margin of the same hue. (B. M. 3733.)

 spotted, blotched, and barred with reddish-brown ; lip 

 having at its base a number of tubercles, curiously 

 arranged, and studded with little button-like knobs. 

 Spring. Brazil, 1842. A curious and handsome species. 



O. pellogramma (blackish-dotted), fl. pale yellow, 

 slightly marked with pallid dots and bars, paniculate. 

 Chiriqui, 1871. 



O. Phalsenopsis (moth-like).* fl., sepals and petals 

 nearly equal, of a soft cream colour, beautifully spotted 

 and streaked with crimson and violet ; lip large, ground 

 colour creamy-white, having a rich yellow crest, and 

 covered with spots and bars in a similar manner to the 

 sepals and petals ; spike erect, three to six-flowered. I. 

 twin, narrow, borne upon the summit of the ovate, deep 

 green pseudo-bulbs, which are Sin. long. Peru, 1869. A 

 beautiful, dwarf-growing species, blossoming at various 

 periods, and continuing a long time in full beauty. 

 When out of flower, it cannot be distinguished from some 

 of the varieties of 0. cucullatum. (I. H. 1870, 13.) [C.] 



O. phylloglossum (leaf-tongued). fl. shining, light 

 horse-chestnut-brown ; sepals and petals bordered with 

 light yellow, the odd sepal and the petals being un- 

 usually wavy ; lip with yellow borders at the very base 

 and a white top, triangular ; calli light yellow ; panicle 

 branched. I. cuneate-lanceolate, acutish. Pseudo-bulbs 

 oblong-pyriform, two-leaved. Columbia, 1880. 



O. pbymatochilum (long-lipped), fl., sepals and petals yellow 

 and reddish-brown ; lip white. Summer. I. dark green, about 

 1ft. long. Pseudo-bulbs thick. Brazil, 1844. A very pretty species, 

 with remarkably curious flowers. (B. M. 5214.) 



O. plagianthnm (athwart-flowered), fl. brown, with oblong 

 sepals and petals ; lip triangular. A curious species. 



O. planilabre (flat-lipped), fl. yellow ; sepals and petals lanceo- 

 late, acuminate, wavy, nearly equal ; middle segment of lip semi- 

 circular, flat ; crest rhomboid, cuspidate ; raceme simple. Autumn.

 coloured tips ; lip cinnamon colour, with an orange callosity, 

 and some deeper spots. New Grenada, 1868. 



O. prsestans (excelling). A hybrid, probably between 0. dasy- 

 style and some species like 0. Gardneri. It is superior to the 

 first, has brighter colours, but lacks the blackish border of the 

 basilar portion of the lip, and it resembles the last in the system 

 of calli. 



O. prsetextum (bordered).* fl. very fragrant ; sepals and petals 

 brown, edged and barred yellow ; lip yellow, with a margin of 

 brown, broken with yellow blotches and linps. Brazil, 1876. A
