referred to Miltonia by Mr. J. O'Brien. The others are, Odontoglossum 

 Reichenheimii, Lind. and Rchb. f., O. laeve, Lindl., and O. leucomelas, 

 Rchb. f., a species which seems to have been lost sight of. O. lseve differs 

 from the others in having a broad unguis to the lip, nearly parallel to the 

 column, from which the limb is sharply reflexed, but in other respects it 

 agrees with this group. The affinity of the group is with Miltonia rather 

 than Odontoglossum, though the limits of the latter genus are difficult 

 to define. 



Miltonia seems to comprise three distinct geographical groups. First 

 Miltonia proper, comprising the well known Brazilian species, M. spectabilis, 

 Clowesii, Regnellii, Candida, flavescens, and a few others ; second, the 

 Colombian group, containing M. vexillaria, Roezlii, Phalsenopsis, and 

 Endresii ; and, third, the Central American group, containing the following 

 species:— 



1. M. Karwinskii, Lindl. (references and history given above). 



2. M. Schrcederiana, O'Brien in Gard. Chron., 1889, ii., p. 210; 

 Veitch Man. Orch., viii., p. 107, with fig. ; Cogn. Ic, Milt., t. 3. 

 Odontoglossum Schrcederianum, Rchb. f., in Gard. Chron., 1887, i., p. 364 ; 

 Orch. Alb., viii., t. 342 ; Reichenbachia, ser. 2, ii., p. 105, t. 96. 



3. M. Reichenheimii. Odontoglossum Reichenheimii, Lind. and 

 Rchb. f. in Bonpl., 1855, p. 214; Pescatorea, t. 19; Batem. Monagr. Odont. 

 t. 15; Warn. Sel. Orch., ii., t. 16. O. lseve, Lem. ///. Hori., vi., t. 213 

 (not of Lindl.). 



4. M. leucomelas. Odontoglossum leucomelas, Rchb. f., in Bot. 

 Zeit., 1864, p. 415. 



5. M. l.evis. Odontoglossum lave, Lindl. Bot. Reg., 1844, t. 39 ; 

 Batem. Monagr. Odont., 1. 16; Bot. Mag., t. 6265; Veitch Man. Orch., i., p. 42 : 

 (excl. syn.). 



Thus the genus is somewhat analogous with Cattleya and some others 

 in its distribution, which is not surprising considering how similar are the 

 conditions under which the plants grow. 



Since the above was written, Mr. Robbins has sent a note from the late 

 Mr. W. Vanner's Note-Book ; as follows :— " Bought at Protheroe and 

 Morris' Sale Rooms in August, 1885, as Odontoglossum sp., flowering the 

 following year, when it was sent to Reichenbach, and named by him 

 Odontoglossum Karwinskii." Mr. Robbins adds that he has had much 

 difficulty in growing it, and he thinks that this is the third time that it has 

 flowered since they have had it. It is also interesting to add that the spike 

 has been sent to Kew for preservation. 



It would be interesting to re-introduce it, and to know more of the 

 conditions under which it grows.
