OcToBER, 1916.] THE ORCHID REVIEW. 243 
species. It is imported from time to time by the Brazilian Orchid 
collectors, but we have failed to find out how far the white and purple 
forms grow intermixed, Mr. J. J. Keevil, in an interesting article on 
Brazilian Orchids (O-R., xviii. pp. 28-30), included it among species that 
might be found within a short distance of Santos, growing on trees that edge 
the railway, together with Cattleya Leopoldii, C. intermedia, and a score of 
other Orchids, but he gave no other details. From a variety of considera- 
tions, however, we are inclined to regard the purple as the typical form. 
We once saw animported batch, of which many were in bloom, and all 
fairly alike. The whites, on the other hand, vary much, and never seem to 
be common, and in the absence of more definite information we are 
inclined to think that they represent varying phases of albinism of a purple 
species, and that one of these happened to be described first. Perhaps 
some of our Brazilian correspondents will kindly give some information on 
these points, which would be very interesting. There are indications that 
the species is widely diffused, it having been recorded from the provinces 
of Rio de Janeiro, Sao Paulo, Minas Geraes, and Bahia, but more details 
of its habitat are required. 
There is, however, evidence that the species of Miltonia grow more or less 
intermixed, for natural hybrids are common, and a pretty full article on the 
subject was given a few years ago (O.R., ix. pp. 289-295). There are four 
natural hybrids of M. spectabilis, the second parents being M. flavescens, 
M. Clowesii, M. candida, and M. Regnellii, the hybrids being called 
respectively, M. festiva, M. Bluntii, M. leucoglossa and M. Cogniauxiz, 
the latter haying the earlier name of M. Peetersiana, Gower. This name 
was set aside because of an earlier M. Peetersiana, Rchb. f., which, how- 
ever, proves to be a variety of M. Bluntii. Reichenbach appears to have 
included the hybrids of M. Clowesit with both M. Regnellii and M. 
spectabilis under one specific name, calling the former M. Peetersiana 
and the latter M. Peetersiana var. concolor. In the former the M. 
Clowesii markings and shape of the lip are unmistakable, as shown 
in an authentic figure (Cogn. Dict, Ic. Orch.), while in the latter 
both characters are as obviously those of M. Regnellii, as shown in a 
painting by Mr. Day (Orch. Draw., li. t. 37). This was made in September, 
1886, at Mr. Bull’s, from a plant purchased at Protheroe’s, and was 
authenticated by Reichenbach, so that there can be no question of its 
correctness, and it agrees with the plant afterwards called M. Cogniauxiz, 
except in being slightly lighter in colour. 
There is now evidence of the existence 0 
M. spectabilis, namely, with M. cuneata, for the 
Rodriguez as M. Rosina (Ger. et Sp. Orch. Nov., i. p- 99), and of which a 
is quite intermediate between the two. 
€ another natural hybrid of 
plant described by 
painting is now preserved at Kew,
