206 THE ORCHID REVIEW. 
macolosum Schréderi as a new variety. Surely this is a little incursion 
into ancient history, for the first dates from 1881, the second from 1886, 
and the third from 1879, all being described by Reichenbach, while the 
fourth actually dates back to the time of Henfrey. Polystachya 
Lawrenceana and Odontoglossum crispum xanthotes have also been 
described months ago. All of which is very confusing, or amusing, 
according to which way you look at it. The moral is obvious. Another 
contemporary describes Bifrenaria tyrianthina as “the last Orchid described 
by Reichenbach.” It is only necessary to add that the name appeared as 
early as 1854, and an excellent figure ten years later. :

M. BARBOSA RODRIGUES’S BRAZILIAN 
CATTLEYAS. 
SEVERAL Brazilian Cattleyas were described by M. Barbosa Rodrigues in 
his Genera et Species Orchidearum novarum, published in 1877 and 1881. 
Through the kindness of Prof. Cogniaux, who is monographing the Brazilian 
Orchids for Martius’ Flora Brasiliensis, 1 have been enabled to inspect the 
original coloured drawings, and now offer the following notes respecting 
them :— 
Cattleya princeps (Rodr. Gen. et Sp. Orch. nov., i. p. 68) is C. Walkeriana, 
Gardn. 
C, trilabiata (Rodr., l.c., p. 69) is C. Warneri, T. Moore, a light rosy 
form, with the lateral sepals somewhat enlarged, and showing an approach 
to the character of the lip in colour. 
C. trichopiliochila (Rodr., l.c., p. 70) is C. Eldorado, Linden, a form 
with pale rosy segments. 
C. eximia (Rodr., l.c., p. 70).—Of this, unfortunately, no drawing was 
found in the collection, but it is described as having much affinity with C. 
Walkeriana, though differing in having much longer, cylindrical pseudobulbs, 
which are monophyllous or diphyllous. Thus it appears to be identical with 
C. dolosa, Rchb. f, 
C. elongata (Rodr., l.c., p. 72) is C. Alexandre, L. Lind. and Rolfe 
(Gard. Chron., 1892, i. p- 522), and the former, as the older name, must be 
adopted. It was certainly overlooked when C. Alexandre was described. 
The raceme bears four light rosy flowers, most like those of the variety 
elegans (Lindenia, viii. t. 358). 
C. fragrans (Rodr., l.c., P- 72) is a light-coloured form of C. velutina, 
chb. f. 
C. alutacea (Rodr., l.c., i. p. 1§7).is C. velutina, Rchb. f. 
C. purpurina (Rodr., I.c., ii. p- 158).—OF this also no drawing was found,
