terminating the young branches. The lobes of the calyx are five, obtuse, short ; the corolla is salver-shaped with its 

 five flat lobes oblong and emarginate, while the tube is slightly enlarged upwards. M. Planchon makes the following 

 remarks upon the genus in the Flore des Serves, t. 442. 



"By a great good fortune we are able to create at least two well defined genera from the chaos of different species 

 thrown together under the name of RonMetia. and to make one of these genera known by four new species, all 

 ornamental. 



" The four species of Rogiera, of which we speak, inhabitants of the temperate regions of Guatemala, where Lycaste 

 SUmicri is found in its glory, produced, in M. Yan Houtte's houses, their corymbs of pretty pink flowers, the limb 

 of which, spleading like a star, encloses a tuft of golden hairs by which their throat is closed. Their want of size 



and brilliancy is compensated by the 

 time which they last, their agreeable 

 though slight odour, their profusion, and 

 delicate colour. All four species are 

 much alike, their differences being such 

 as none but a botanist can appreciate. 

 Their general appearance, their foliage, 

 their stipules, their inflorescence, are all 

 similar. They form a perfectly natural 

 genus, approaching Rondclvtia, but dis- 

 tinguished from it by the absence of the 

 prominent ring in the throat of the 

 corolla." To this M. Van Houtte adds 

 the following remarks upon their cultiva- 

 tion : — 



" The Rogieras, like the splendid 

 epiphyte Lycaste Skinneri which their 

 branches perhaps 

 support, inhabit the 

 high, and conse- 

 quently temperate 

 regions of Guate- 

 mala. They grow 

 vigorously in our 

 climate in the open 

 air, in the shade in 

 summer, and are 

 contented with a 

 cold or temperate 

 house in winter. If 

 cultivated in a hot- 

 house their period of flowering is hastened, as it may be also by other means. The soil they prefer is a light mixture of 

 peat or leaf-mould and a little sand. They should be frequently watered. They may be propagated by cuttings, 

 under a bell-glass, in a moist atmosphere and on a warm bottom." 



The four species which M. Planchon enumerates are R. aincena, Mcnechma, Roezlii, and cleg cms ; they seem to differ 

 in very slight circumstances. In the same work this author proposes a genus, also cut off Rondeletia, for which he 

 offers the name of Arachnothryx, and to which he refers the Rondeletias oudclleioid.es, lamflora; and reflexa of Bentham 

 with the discolor of Humboldt and some others. 



Cypkjpedium gkande. H. G. Reic7ienbach, f. This is a most promising hybrid 

 variety, raised by Mr. Seden, at Messrs. Veitch's Royal Exotic Nursery; the result of 

 a cross between C. caudatum and C. Roezlii. 



A strong, vigorous growing plant, more so than the dark variety of C. caudatum. From its parentage it can 

 scarcely fail to be a fine thing when the plants get fully established. 



Calanthe BarbeeIx\na. II. G. ReicJieniach,/. A beautiful hybrid variety , raised by 

 Mr. J. T. Barber, Old Hall, Spondon, Derby. 



A robust grower, with flowers of the C. vestita character, but more slender, of the purest white, yellow at 

 the base of the lip and at the inferior face of the column, in some cases with a slight dash purple in front of 

 the area. — Gardener's Chronicle, N.S., vol. xv., p. 136.
