ORCHID CONFERENCE. 



85 



Pescatorei. — A small genus of leafy evergreen orchids, 

 nearly related, indeed now generally referred, to Zygopetalum. 

 P. Lelimanni, the only species represented, lias showy, purplish 

 flowers, with a curiously ridged disc on the lip. 



Phaius. — Three species were shown, viz., P. maculatus, 

 P. grandifolius var. Wallichii, and P. albus, the last-named being 

 a deciduous-leaved plant, with elongated rod-like pseudo-bulbs, 

 and now more generally called " Thunia alba " in gardens. All 

 are well-known garden plants. 



Phal^nopsis. — These " Moth Orchids," as they are popularly 

 called, comprise the very elite of the epiphytal Orchids, so far as 

 beauty and graceful habit are concerned. Unfortunately, they 

 are not easy to grow successfully many years together. Only 

 four kinds were shown, viz., P. Parishii, a splendidly-grown plant 

 from the Kew collection ; P. Luddemannia, P. tetraspis, a rare 

 novelty, with milk-white flowers ; and, above all, the lovely rose- 

 tinged variety of P. amabilis (the queen of Orchids), known as 

 Sanderiana, a lovely plant from a little visited island of the 

 Philippine Archipelago. 



Polystachya. — A small genus of Orchids from the West 

 Indian Islands, P. pubescens having erect spikes of yellowish 

 flowers, the sepals being lined or streaked with purple. Kew. 



Ponthieva. — Terrestrial South American herbs near Neottia. 

 P. maculata, the species represented, has spotted leaves. 



Eenanthera. — A showy genus of Eastern epiphytes, near 

 Vanda. R. coccinea, the species exhibited (not in bloom), 

 comes from China, and bears large panicles of Indian red, 

 yellow-barred flowers ; a remarkable plant, well grown at Chats- 

 worth and elsewhere. 



Restrepia. — A most interesting little group of plants. R. 

 antennifera, the plant shown, having yellow flowers dotted with 

 purple and long antennae-like petals. 



Saccolabium. — Only two species of this showy genus were 

 represented, viz., S. retusum and S. ampullaceum, neither 

 remarkable as showing good culture.
