48 ZYGOPETALUM. 



One of the discoveries of Warscewicz in 1849 — 50 on the volcano 

 of Chiriqui in Veragua at 8,000 feet elevation it is said, but this 

 is probably excessive, as one of our own collectors reported it at 

 2,000^3,000 feet growing under climatic conditions similar to those 

 described under Zygopetahim Biirtii. It was first cultivated in this 

 country by the late Mr. Sigismund Rucker, at "West Hill, Wands- 

 worth, who appears to have been the sole possessor of the species 

 till imported by us in 1865. Occasional importations since that 

 date have caused it to be one of the best known and most 

 generally cultivated species of its section. 



Z. cochleare. 



Pseudo-bulbs none. Leaves broadly oblanceolate, 7 — 12 inches long, 



cuneate below into a broad channelled foot-stalk. Pedvmcles shorter 



than the leaves, sheathed at the base by an oblong acute bract, and 



by a similar smaller one at the base of the ovary, one - flowered. 



Flowers delightfully fragrant, 2| inches in diameter ; sepals and petals 



of wax-like texture, French-wliite, the dorsal sepal and petals narrowly 



oblong, acute ; the lateral sepals broader, ovate, oblong, greenish yellow 



at the apex; lip sub-quadrate, concave towards the base, slightly reflexed 



at the apex, white with broad, close-set, violet-purple longitudinal lines ; 



crest semi-lunate, frilled. Column semi-terete, clavate, French - white 



stained with violet-pmple below the stigma.

Discovered by Descourtilz in the early part of the present century 

 on the high mountains separating the provinces of Sao Paulo and 

 Minas Geraes, in southern Brazil, and first introduced in 1835 — 6 

 by our predecessor, Mr. Knight. Its pleasant fragrance is its chief 

 recommendation. We are indebted to Sir Trevor Lawrence, Bart., 

 for materials for description. 



Z. coeleste. 



Pseudo-bulbs none. Leaves 6 — 10 to each growth, oblong-lanceolate, 

 acuminate, 6 — 12 inches long, 1| — 2 inches broad. Peduncles stoutish, 

 sub-erect or nodding, shorter than the leaves, with a small sheathing 

 bract at each joint, one - flowered. Flowers 3 — i inches in diameter, 

 the sepals and petals bluish violet, paler at the margin and base, 

 yellowish at the tips ; the dorsal sepal broadly obovate and bent 

 forwards, the lateral two oval-oblong; the petals like the dorsal sepal, 

 but more spreading; lip shorter than the other segments, with a larger
