points, the petals very long, erect, twisted, deep purple, and the 

 oblong lip whitish, crispy, purplish violet at the apex, and 

 having three elevated lines along the centre. It is best grown 

 in a pot in peat. We seldom see good plants of this species 

 under cultivation. — Philippine Islands : Manilla.

D. teretifoliuiQ, R. Br. — A curious-looking species, very 

 distinct in habit, which is worth growing on account of the 

 profusion of flowers it produces in the winter months. The 

 stems are clustered, dark brown, branched, each branch ter- 

 minating in a long pendent curved terete taper-pointed hard 

 fleshy leaf, very much resembling that of a Scuticaria. The 

 flowers are produced in lateral dichotomously-branched 

 panicles from a branch of the stem ; the sepals and petals are 

 both linear-filiform and white, the latter being longer than 

 the former, and the lip, which bears three wavy lamellae is 

 much crisped, and strongly reflexed, white with a few dots of 

 crimson. — North-East Australia.

D. thyrsiflorum, Hon. — A fine showy species, in habit 

 like D. densiflorurn, but stronger, with the apex of the stems 

 yellowish, and producing splendid clusters of white flowers 

 with a golden orange lip. There have been some large 

 importations of late, and in many cases very fine varieties 

 have been obtained, varying both in the colour of the flowers 

 and the size of spike. This is one of the handsomest of 

 Dendrobes, and is most suitable for exhibition purposes, its 

 fine drooping racemes producing a charming efi"ect when 

 placed beside other Orchids. — Moulmein.

D. thyrsiflorum Walkerianum, Williams. — This is the 

 finest variety we have yet seen : the stems are three feet 

 in height, and the racemes of flowers two feet long, bearing 

 more than fifty flowers on one raceme. The blossoms are very 

 large, and of the same colour as those of D. thyrsifionm. 

 This is named in honour of C. "Walker, Esq., Brettagh Holt, 

 AVestmoreland. — Moulmein.
