Plocoglottis. 

 tree abo\-e ; anthers two-celled ; pollinia four, round, with 

 two long, replicate caudicles ; peduncles or scapes leafless. 

 Leaves ample, membranous, plicate. Stem or rhizomes 

 creeping, one- or many-leaved, not distinctly pseudo-bulbous 

 at base. The three species that may be occasionall\' met 

 with are P. acuminata (Bliiiiic), P. javatiica (Blitiiic), and 

 P. Toi^'ii i Rl/iIk f.\ The}' require similar culture to 

 Cn'tof'odium. 



PODOCHILUS. 



A small genus of epiphytal Orchids, nati\'es of the 

 East Indies, belonging to the tribe J'aJidire. The name 

 given b)- Blume is from />o/is, /'odos, a foot, and c/icilos, 

 a lip ; the lip is joined to the column by a foot or stalk. 

 Flowers small, often minute, disposed in terminal racemes ; 

 sepals erect, conni\'ent ; petals almost equal to the dorsal 

 sepal, or narro^'er ; bracts small. Leaves small, distichous. 

 P. longicalcaratus ( Rolfe) ma)' be found in botanic 

 collections. It requires East Indian-house treatment. 



POQONIA. 



0\'er thirt)- species Twidel}' dispersedj of stove, terrestrial 

 Orchids are included in this genus, founded by Jussieu, 

 and belonging to the tribe Ncotticcv. The name is from 

 pogoiiias, bearded, referring to the fringed lip of some of 

 the original species. Flowers solitary or looseh' racemose, 

 having free, conniving, or somewhat ringent sepals and 

 petals, either all equal or the petals smaller ; a free, erect, 

 undivided or lobed lip, with its disk crested or papillose ; 

 a long semi-terete, clavate column, eared or winged at 

 the top ; and a sessile or very shortly-stalked two-celled 

 anther, containing two furrowed pollen-masses. The plants 

 have either one or a kw sessile leaves upon an erect stem 

 at the period of flowering, or are leafless till after flower- 

 ing, and then produce a solitary, stalked leaf from an 

 underground stem. The species thrive best in well-drained 

 pots in a compost consisting of loam, leaf-soil, sand, and 

 living sphagnum. Liberal root moisture is required during 

 the gro\\'ing season, and a thorough rest in a cool, air\- 

 position is ad\-isable during the period in which the plants 

 are in a dormant state.
