PROMENAEA — RENANTHERA. 691 



P. MICROPTERA, BoKb.f. — A distinct and pretty little species introduced 

 by ourselves, and related to P. xanthina. The sepals and petals are creamy- 

 white or light ochre-coloured, and the lip, which has the front lobe elongate and 

 lance-shaped, and the two lateral lobes minute, is white, having three transverse 

 bars of dull crimson on the disk, and small purple spots at the base. It ilowers 

 during the summer months. — Brazil. 



Sys. — Zijgopetalum mUirojaterum . 



P- ROLLISSONl, Lindl. — A curious little plant with roundish compressed 

 pseudobulbs, bearing about two oblong-lanceolate venose leaves from the top 

 and other accessory ones from the base. The deflexed scapes come from the 

 axils of the latter, and bear one or two pale yellow flowers during the autumn 

 months, lasting three weeks or more in beauty; the lip is whitish with the 

 middle lobe oblong, apiculate, and the lateral lobes narrow ovate acute, like 

 two erect ears standing up from the base, the whole being spotted with 

 crimson. — Brazil.

 SrN . — MaxiUaria MoUissoni ; Zygojietalum RoUissoni. 



P. STAPELIOIDES, Lindl. — An interesting and pleasing species, remarkable 

 for its singular speckled flowers, which have suggested the specific name. The 

 pseudobulbs are small, ovate, tetragonal, one- or two-leaved, the leaves lanceo- 

 late, thin, light green, with a pale glaucous reticulation ; the peduncle is 

 deflexed, two-flowered, the sepals and petals roundish ovate, acute, spreading, 

 greenish-yellow, transversely spotted and barred with dark purple ; the lip 

 deep purple approaching to black, oblong, three-lobed, the lateral lobes erect 

 linear, the terminal one ovate oblong, cacullate at the base, the margins paler 

 and cross-barred. It blooms in July, August, and September, and lasts long 

 in perfection.- — Brazil.

RENANTHERA, Loureiro. 



(Trite Vandeae, subtriie Sarcantheae.) 



This genus, which is very nearly allied to Vanda, consists of showy 

 plants, with climbing branching stems, clothed with distichous leaves, 

 and bearing elegant panicles of flowers, which in some cases are of a 

 very showy character, on lateral peduncles. They have spreading sepals 

 and petals, the lateral sepals often broader and longer, contiguous or 

 somewhat coherent, and a short lip articulated with the base of the 

 column, and produced at the base into a conical spur. There are some 

 half-dozen species found in Tropical Asia and the Malay Archipelago, 

 some of which are in high favour with Orchid growers. R. Loivii, the 

 Vanda Loivii of many gardens, is placed in Arachnanthe by Bentham.
