NoveEMBER, IgtI.] THE ORCHID REVIEW. 
ONCIDIUM MANTINII. 
THE annexed figure represents part of an inflorescence of the beautiful 
Oncidium Mantinii which appeared in the establishment of Messrs. Hugh 
Low & Co. some years ago. We do not know its precise history, but it 
agrees well with the original O. Mantinii, which appeared in the establish- 
ment of M. Truffaut, at Marseilles, whence it passed into the collection of 
M. G. Mantin, Olivet, near Orleans, and was described by M. Godefroy 
Lebeuf as probably a natural hybrid between O. Marshallianum and O. 
Gardneri, or possibly O. sarcodes (Orchidoph., 1888, p. 47, with plate). It

is said to have been received from M. Binot, of Petropolis, in an importa- 
tion of O. crispum. We have considered O. Forbesii and O. Marshallianum 
as the more likely parents, and have suggested (O. R., i. p. 299) that it may 
be a form of the earlier and long-lost O. pectorale, Lindl. (Sert. Orch., t. 39), 
but the three dried flowers in the Lindley Herbarium are so much smaller 
that the suggestion may be incorrect, and the latter may have a different 
origin. We have not yet made much progress in clearing up the origin of 
the various natural Oncidiums, and it would be interesting if our hybridists 
would make a few experiments. R.A.R.
