﻿326 THE ORCHID REVIEW. [November, 1904. 



of the species, having brownish sepals and petals, a little marbled with 

 green, and a deep bluish-violet lip veined with white. The crest of the lip 

 is clearly striped with blue, and the column is streaked with dull dark 

 purple. M. de Jonghe stated that it had been found by his collector Libon, 

 in 1847, on the Peak of Itabari, in the province of Minas, in Brazil.*' A 

 woodcut of a flower was also given {Journ. Hort. Soc, Lond., iv., Proc, pp. 

 II, 12, with fig.). 



In 1S55 Regel described Z. Mackayi var. parviflorum (Ind. Sem. Hort. 

 Petrop. 1855, p. 22), and Z. M. var. pictum (I.e., p. 23), in each case 

 "Z. intermedium, Hort. Petrop." being cited as synonymous. The former 

 he described as having flowers half as large as the type, being scarcely ii 

 inches in diameter, and the latter as having tl iwers of the size of the genuine 

 form, but the sepals and petals narrower, and the lip white, beautifully 

 spotted with violet. 



Z. Mackaii and Z. intermedium were by this time hopelessly confused, 

 and when Reichenbach revised the genus in 1863 he made them synonymous 

 (Walp. Ann., vi., p. 661), remarking that they could not be separated by the 

 glabrous and pubescent lips, as supposed by Lindley. The only two varieties 

 admitted were those described by Regel, already mentioned, and Z. brachy- 

 petalum was admitted as a distinct species. 



It may be interesting to add that Mr. Day's valuable collection of Orchid 

 drawings also throws further light on the question. In December, 1863, a 

 sketch of a flower from the collection of Mr. Basset was drawn by Mr. Day, 

 and it is labelled " Z. Mackayi — or intermedium ? " [Coll. Draw., v., p. 65). 

 In December, 1876, a coloured drawing of Z. Mackayi" was made, to 

 which is appended the note : " I bought this particular plant at Bishop 

 Sumner's sale, some years since. It is a good ordinary variety, but nothing 

 out of the common way — perhaps a little larger than the average." Both 

 these figures belong toZ. intermedium, which it may be added is not other- 

 wise illustrated in the collection. 



There is also a drawing of a plant, made in October, 1885, "at Kew 

 Gardens," and at first labelled Z. intermedium, but afterwards changed to 

 Z. brachypetalum. in accordance with the following note : " Prof. Reichen- 

 bach saw this drawing in Sept., '86, and immediately exclaimed 

 ' brachypetalum,' so I have altered it accordingly." We strongly suspect 

 this was the "Z. intermedium, Hort. Petrop." which was given as a 

 synonym of Z. Mackayi var. parviflorum, Regel. 



More recently Reichenbach pointed out the confusion in which Z. 

 ' ' ■ • 1 '■ ■ -. - r. 7. r. r . ] 



acknowledged that the two species were confused in Walpers Annalcs, 

 adding:-— " For years Z. intermedium alone was to be found in gardens, 

 but of recent years the Hookerian plant has appeared here and there."
