May-JUNE, 1919.] THE ORCHID REVIEW. 75: 
Further observation on the presistence of hybrids in Australia’ would be 
interesting, for experience here suggests that under suitable conditions they 
should continue to flourish. Attempts to perpetuate them from seed is a- 
quite different matter, on which a few experiments would be interesting, 
which our Australian friends might attempt to carry out.—R. A. R. 
LycasTE SKINNERI ALBA.—We regret to see that Mr. T. D. A. Cockerell 
has now described the beautiful Lycaste Skinneri alba as a distinct species,. 
under the name of L. alba (Torreya, 1919, p. 10). Speaking of some plants. 
purchased in Guatemala City, but which were brought from the surround- 
ing country by the natives, Mr. Cockerell remarks: ‘‘ After comparing the 
living plants with typical L. Skinneri, flowering at the same time, I came 
to the conclusion that the so-called L. Skinneri alba was a distinct species. 
It apparently occurs wild, and in spite of assertions to the contrary, it 
certainly has structural as well as colour characteristics.” A note on the 
plant has previously been given (O.R., xxiv. p. 60), and Mr. Cockerell now 
remarks: ‘‘ As no more light has come to clear up the matter, and it still 
seems to me at least probable that the white form should be separated, I 
offer a brief description from our material.” The trouble is that Mr. 
Cockerell has got a form of L. Skinneri afflicted with albinism, and there 
are other forms afflicted in the same way. They certainly occur wild, until 
they are picked out for garden purposes on account of the chaste and 
beautiful colour. Collectively, they differ from L. Skinneri in albinism, a 
condition that operates on forms that are dissimilar in other respects. And 
how many species might not be carved out of the variable L. Skinneri on: 
the same methods !—R. A. ROLFE.

Orcuips oF OrtzaBA.—I read with particular interest the notes at 
Pp. 43, 44, respecting the habitat of Odontoglossum cordatum and O.* 
maculatum in Mexico, and the mention in connection therewith of 
O. Rossii. For I once collected the latter, in flower, in the Sierra Juarez,. 
Oaxaca, at an elevation of probably between 9,000 and 10,000 feet. T well 
remember that, to get the plant, I had to hew down the tree upon which it 
grew, because it could not be climbed. I resided for some time at Orizaba,. 
and was aware that O. Rossii occurred in the surrounding mountains, but 
the favourable occasion to look for it did not occur. The pretty Cattleya. 
Citrina was also to be found there. Lycaste aromatica and various 
Sobralias were common in the same locality, but not so high up. Orizaba 
is situated at about 5,000 feet above sea level. Several thousand feet lower, 
and nearer Vera Cruz, Brassavola glauca had its habitat. Mr. J.C. Harvey 
and I together once made a fine bag of this plant, close to Paso del Macho,. 
on the Mexican Railway.—J. L. HERMESSEN. :
