OXCTDIUM VARTCOSUM ROGERSTI. 



A splendid *mve epiphyte, remarkable for the size and number of iu largo yellow flowers. The pscudobulbs nre 

 oblong-ovate, somewhat compressed, furrowed, and bearing from their apex a pair of ligulatc lanceolate leaver 

 which are of si dark green colour* a foot long, and terminate in an acute point. The flowers grow in a large 

 densely-branched nodding panicle, which sometimes consisUof as many nsI70tlowcre,nnd issupportcdonastout 

 scape, which issues from the base of the |>scudobulbs. 'Hie flowera nre very huge, the lip being the prominent 

 portion, and of a clear bright yellow colour; the sepals are small, the lateral ones connate (whence this plant 

 cornea into the group Tetrapetala), yellow, with biwtibh-ml bars; the petals arc also small, and of a similar 

 colour to the sepals: the lip is very large, with two smaller ear-like basal lobe*, ereuatc in front, and a very 

 large reniform anterior lobe, which is notched along the front margin into four blunt segments ; the colour is 

 a pure bright yellow, with a few transverse bare of red-brown on the constricted base of the middle lobe. 

 The crests of the lip are smaller in this variety than in the type. 'Hie column has oblong denticulate 

 whole-coloured wings.

 Oxcidium Rogrrsii, of garden*. 



This noble species of Onddinm % which was introduced to this country by ])r. Holers, of East 

 Grinstcad, Sussex (after whom the name Itogcrsii is applied to it), certainly proves to be one of the 

 finest and most ornamental of the whole genus, as Ihe accompanying figure abundantly testifies. From the 

 hands of Dr* Itogors it passed into those of Messrs. Veitch and Sous, of Chelsea, by whom it has been 

 several times exhibited in very fine condition. 



The glorious flower-scopes of O t vuricotitm Rogersii, which, like 0, variewnm itself, is a native of 

 Brazil, arc frequently three feci long and upwards. TIence, though there arc many fine members of this 

 genus now adorning our plant-houses, this will always take high rank amongst the most showy and 

 beautiful. More especially will it be valued by those who love winter-blooming Orchids, for it is in the 

 dull days of November and December that it puts forth iu much-branched and many-flowered panicle of 

 pure and brilliant flowers. 



In regard to its general habit of growth, this plant resembles 0. bifolium majvs, hut it is much larger 

 than that variety in all its parts. Its branched spike has been known to bear as many as a hundred and 

 seventy flowers, each measuring nearly two and a half inches in diameter, so that il may readily be conceived 

 what a qorgeous spectacle a well-grown specimen of it must present. The sepals and petals are small, the 

 lip being the most conspicuous part of the flower : this is broad, flat, and spreading, with three deep notches 

 in front. Though the plant in question is considered by Professor Kcichcnbach to be a variety of Oncidhm 

 rarico»um > yet it is vastly superior to that species in every respect; indeed, nothing can be more effective 

 hen well grown than the magnificent spreading panicles which it produces so freely.
