SUb-vars.*— BoxalVs (Gard. Cliron. VII. (1877), p. 749. Hot. Mag. 



t. 6328), sepals and petals paler than in the type, disk of the lip with dark 



blue stripes alternating with light ones, and passing into violet-blue at 



the apical edge; Captcfin Vipan's (Gard. Chron. XXV., p. 752) (1886), 



sepals and petals white, lip stained and spotted with light purple ; Low's 



(Gard. Chron. VIII. (1877), p. 102), sepals and petals light mauve 



suffused with white : lip and cohimn amethyst - purple toned with 



carmine. 



To the energetic Indian explorer, William Griffith, science is also 



indebted for the first discovery of this blue Van da, which, if not so 



striking in aspect as the preceding species, is scarcely less worthy of 



cultivation. Griffith detected it at Psembo, near Bhamo, in Upper 



Burmah, in April, 1837; he made an imperfect sketch of it in situ and 



preserved a dried specimen, both of which were sent to Kew. Nothing 



more was seen of it for thirty years until Colonel (now General) Benson 



re-discovered it on the Arracan Mountains west of Prome, growing 



on deciduous trees at 1,000 — 1,500 feet elevation. A dried specimen 



and coloured drawing were communicated by him to Kew in 1867, 



and in the following year it was introduced by us through him. It 



flowered for the first time in this country in our Chelsea nursery 



in February, 1869. The sub-varieties named after Low and Boxall 



were introduced in 1877 by Messrs. Low and Co, through their collector, 



Boxall, and Captain Vipan^s by the gallant officer whose name it 



bears in 1885 — 6. The usual flowering season of Vanda ccendescens 



is June and July. 



V. concolor. 



Leaves 7 — 9 inches long and about an inch broad, oblic|uely bilobate, 



sometimes tridentate at the apex. Racemes ascending, as long as the

on rather long, greenish, twisted and ribbed pedicels ; sepals and petals
