DENDROBIUM. 359 



D. RHODOPTERYGIUM, RcM. /.—This species is something in the way of 

 I). Parishii; the s';ems, however, are much longer, and more erect. The flowers 

 are pink tinged with rose, and instead of two blotches have on each side the base 

 half a dozen streaks of purple, while the disk is covered with little warts instead 

 of the velvety hairs so conspicuous in D. Parishii — Biu-mah. 



D. RHODOSTOMA, BM. /.—One of Messrs. Veitch's hybrids, produced 

 between D. superhum HiUtoni and B. sanguinolentum. In growth it resembles 



D. MacCarthiae. The flowers are white, the sepals and petals as well as the lip 

 tipped with bright rosy-magenta. It blooms in September. We saw this plant 

 flowering freely in the collection of W. Lee, Esq., Downside, Leatherhead.— 

 (ktrdeii hybrid. 



D. RHOMBEUM — See D. aumuji. 



D. ROLFEAE, Krdnzlin. — " The flowers of this new hybrid have the usual 

 shape of those of B. iiobile, including its lip and broad petals ; the sepals are of a 

 delicate blush colour, white at the base, and light blush-pink at the apex. , 

 The petals are white, tipped with rosy-pink ; the lip sulphur-yellow and white, 

 tipped with bright rose ; the fleshy disk is blush- white, with numerous maroon 

 radiating lines, some broad, others very narrow, on either side, but no maroon 

 blotch in front. The column is bright pea-green, with the anther-case light rosy- 

 purple. Thus it partakes very largely of the pollen parent, and has large, well 

 formed, delicately coloured flowers, over 2f inches in diameter from tip to tip of 

 petals ; petals and lip over 10 lines broad. The influence of B. nohile is very 

 marked in the free growth and blooming character of the plant. It is one of the 

 most charming of the many Bendrohes yet raised, and is dedicated by the raisers, 

 Messrs. F. Sander & Co. of St. Albans, to the wife of our British Orchidist, Mr. 



E. A. Eolfe, of Kew " {Gardeners' Chronicle, 3rd ser., 1892, xi. p. 522). — Qarden hybrid. 



D. " RUBENS," O'Brien. — This hybrid was raised between B. Leechianum and 

 B. nohile iwhilius by Mr. J. Cypher, of Cheltenham, and is named in honour of 

 the Flemish Painter P. P. Eubens. " The sepals are broad and flat, 3J inches 

 across, white, tinged with the peculiar purplish-crimson of B. iiobile nnbilius on 

 the outer halves and reverse side ; petals nearly 4 inches across and 1 inch in 

 width, white, with a purplish-crimson margin, and heavier colouring of a more 

 purple-rose hue at the tips. The lip is less acviminate at the tip than in 

 B. Leechianum; blush white at the base, and with purple lines over the sides 

 which clip the column, the middle of the lip for nearly half its area being of the 

 richest maroon-crimson, which is encircled by a broad white band, the tip being 

 of purplish-rose colour, like the tips of the other segments. Compared with 

 B. Leechianiiin, it has the shining white and bright colour of B. nohile nobilius, 

 instead of the creamy -white and duller colour of that variety, and the colouring 

 of the lip is full, the margin of the blotch only being a little broken, and not 

 displayed in veinmg as in the varieties of B.Ainsworthii. In growth and freeness 

 of habit it resembles B. splendidissimun grandijlorum" (J. O'Brien, in Gardeners' 

 Chronicle, 3rd ser., 1893, xiii. p. 226). — Gcirden hybrid.
