ACINETA. 131 



in whose garden at Spring6eld, near Birmingham^ it flowered in the 

 following year. It was a great favourite with the orchid amateurs 

 of that period, and it is still occasionally seen. 



A. densa. 



Pseudo-bulbs narrowly fusiform or sub-conic, 3 — 4 inches long, bearing 



at their apex 3 — 4 oblanceolate, acute, plaited leaves, 12 — -18 inches 



long. Kacemes 2 — 3 feet long, pendulous, many-flowered ; bracts oblong, 



acute, brownish. Flowers fragrant, not fully expanding ; sepals light 



yellow, concave, oval-oblong, obtuse, the lateral two a little longer 



than the dorsal one ; petals similar to the dorsal sepal but smaller, 



light yellow spotted with red, the spots aggregated towards the base ; 



lip very fleshy, yellow densely spotted and blotched with red-brown ; 



the claw nearly quadrate, concave with a conical protuberance on the 



front side ; the side lobes oblong-rotund, erect, concave ; the intermediate 



lobe much smaller, oblong, slightly incurved ; disk a fleshy plate with 



a raised median line, tridentate in front. Column stoutish, pubescent

A native of Turialba^ in Costa Rica, where it was discovered in 1819 

 by Warscewicz^ from whom it was obtained by Mr. G. Ure Skinner 

 for the Horticultural Society of London and for some of the most 

 prominent orchid amateurs of that period including Bishop Sumner, 

 in whose collection at Farnham Castle it seems to have flowered for 

 the first time in this country, but not till several years after its 

 introduction. It flowered simultaneously in the Royal Gardens at 

 Kew and Glasnevin in the autumn of 1889, whence we obtained 

 materials for description. As a species it is comparable with Acineta 

 BarJicri, to which it is superior in its larger, more open and brighter 

 coloured flowers ; but it is, unfortunately, a shy bloomer and it has 

 now become quite rare in the orchid collections of this country. 



A. Humboldtii. 



Pseudo-bulbs ovoid, angulate, 3—4 inches long, di-triphyllous. Leaves 

 lanceolate, acute, 10 — 15 inches long, 1 — 2 inches broad, narrowed 

 below into a channelled foot-stalk, strongly nerved beuGath. Scapes 

 stoutish, as long as the leaves, quite pendulous, 5 — 7 or more flowered; 

 bracts ovate, acute, sheathing, half as long as the ovaries. Flowers 

 not fidly expanding, faintly but pleasantly fragrant; 2— 2| inches in 

 diameter ; sometimes reddish brown, sometimes light tawny yellow, 

 but always spotted with red or brown-purple ; dorsal sepal broadly
