﻿THE ORCHID REVIEW. 



Mr. Boxall, who is now a member of the Orchid Committee of the Royal 

 Horticultural Society. P. Cobbiana flowers rather late in the autumn. Its 

 zigzag rachis is very peculiar, densely flowered, and the flowers are small, 

 and pale straw yellow, with an orange yellow lip. The cultural directions 

 given concerning P. filiformis are also applicable to the other species 

 enumerated, and they are all well worth adding to every Orchid collection.

ODONTOGLOSSUM x BRANDTII. 



A very interesting plant was exhibited at the R.H.S. meeting at Holland 

 House, Kensington, on July 12th, by Herr Otto Beyrcdt, of Berlin, namely, 

 Odontoglossum Brandtii (Kranzl & Wittm.. in Gavtcnfl., xxxviii., pp. 378 

 537, t. 1308). It was described in 1889 as a new species, from the collection 

 of Herr R. Brandt, of Charlottenburg, allied to O. Pescatorei, O. cirrhosum 

 and O. hastilabium — which, by the way, belong to three different groups. 

 From the examination of the figure I came to the conclusion that it must 

 be a natural hybrid, and at first referred it doubtfully to O. X excellens 

 (Orch. Rev., ii., pp. 200, 201), but afterwards to O. X lepidum (/. c, xi., 

 p. 35). An inspection of Herr Beyrodt's authentic plant shows that the 

 latter view was correct, and also that the figure is somewhat inaccurate. 

 The sepals are narrower, and more acuminate than represented, and the lip 

 also too broad, and these discrepancies of course added to the difficulty of 

 recognising it — in fact prevented its being identified with O. X elegantius, 

 Rchb. f., which was then well known. It now appears that O. X lepidum, 

 O. X stauroides, and O. X elegantius, ail of Reichenbach, are forms of the 

 same hybrid, to which O. X Brandtii also belongs, the parents being O. 

 Pescatorei and O. Lindleyanum. O. X lepidum was the earlier, being 

 described in 1883 (Card. Chron., 1883, ii., p. 526). Its history has already 

 been given (O. A'., ix., p. 56). The plant exhibited bore a branching 

 inflorescence and numerous flowers. The sepals and petals are lanceolate, 

 acuminate, ii to inches long, and the ground colour light yellow, the 

 sepals having an oblong brown marking or a few confluent spots at the 

 base, with a purplish stain behind, and the petals a narrow line at the base. 

 The latter are undulate, and there is an occasional spot on some of the 



broad purple-brown band round the side lobes of the lip, and sometimes 

 a small spot in front of the crest. This latter consists of two diverging 

 lobes with an occasional lateral tooth, and the column wings are small and 

 entire. It is interesting to be able to clear up the history of the plant.
