St.: fls. borne in siniplo or i'i>ni|H)iiiul Uitonil clusU-rs; 

 sepals about equal, sproadinj;, tlu> ilorsal liroailcr than 

 the lateral; petals similar to the dorsal sepal; lip rreet, 

 or bent in, attaeheil to the foot of the cohinm, s])urred 

 at the base, the spur hollow; iiolliiiia 2— .-^peeies

 E. Asia and Japan. 



Nearly all the species of this senus are from the 

 East Indies and therefore require the warmhouse 

 treatment, with a minimum of 0.")° F. in winter. As 

 they have no pseudobulbs, but an erect, evergreen stem, 

 they must never be allowed to become perfectly dry. 

 Ample drainage of charcoal and Ijroken pots is \-ery 

 essential, with a surfacing of moss, preferably- sphag- 

 num, renewed each year, the usual i)eat liber being 

 omittetl. The best-kiiown species is .1. oiloniliiiii nud 

 is often seen in collections flowering freely. .1. FUiil- 

 xugii is also an interesting plant, as the spikes grow to 

 the length of IS inclies, are dense-flowered, and known 

 as the "fox-brush orchid," the color being a beautiful 

 rose-pink. .-1. Laurencur is another fine plant, from 

 the Philippines but not yet common in gardens. — 

 Propagation is effected only by cutting olT the top of 

 the plant and setting it down in another pot, and wait- 

 ing for the other part t6 scud out shoots. The roots are 

 mostly aerial, and no attem]jt must be made to confine 

 these to the pots. If the size pot used is large, it should 

 be perforated at the sides to admit of a free circulation 

 of air. (Orpet.)
