302 | THE ORCHID REVIEW. 
dasytyle: Reichenbach remarked “ there is little doubt of this betiie iia. | 
between O. dasytyle and some species like Gardneri. It is far superior 
to the first, has brighter colour, and a system of calli far nearer that of 
Oncidium Gardneri.” The second parent, however, is not very apparent, 
but I fail to find anything which agrees better with its characters than0, 
Forbesii. 
Oncidium x Pollettianum appeared in the collection of H. M. Pollet 
Esq., Fernside, Bickley, in 1886. Reichenbach, when describing it, sug 
gested that it might be a natural hybrid between O. dasytyle and 0. 
Gardneri. His description states that the flowers are equal to those of 0. 
Gardneri, and the calli long, running from the base over the isthmus, dat 
brown-purple. Mr. Pollett stated that the bulbs and leaves were exatllj 
those of Oncidium dasytyle, say a trifle larger. From this it is evident that 
O. dasytyle was one parent. The other is not so apparent, but from the 
description I think it must have been O. Forbesii. Messrs. Veitch consider 
it synonymous with O. pectorale, but that has evidently a different parett 
age. . 
Had any one suggested Oncidium Gardneri as being a natural hybrids 
year or two ago I should have scouted the idea, but the conviction has bet 
forced upon me by the examination of a series of forms, some of which ® 
strongly resemble O. Forbesii in general character as others do 0. dasytyl 
Especially one which has flowered with Mr. Bull, of Chelsea, on 
occasions, which is precisely O. x Gardneri without any spots, of only 
with the faintest indication of them, as if they were just fading away. Ths 
shows a considerable approach to O. dasytyle, and also helps to bridge ove | 
the gap which separates O. x Gardneri from O. X preestans, the most 
aberrant of the group. a 
This hybrid is evidently a very polymorphic one, as the following wi! |
