42 THE ORCHID REVIEW. [ FEBRUARY, 1906. 
habitat was not recorded, but the same thing afterwards flowered at 
Woburn (Bot. Mag., t. 4099), having been sent from Guatemala by 
Skinner. All three were afterwards recognised as forms of the same 
species. It is said to be sparingly spread over parts of Southern Mexico 
and Guatemala, and is so highly thought of by the inhabitants of the last- 
named country that they call it the Flor de Jesus. It has also been recently 
sent from Costa Rica by Tonduz, who collected in forests at Nicoya. It 
is somewhat variable, both in size and colour, and the best dark forms are 
very attractive. The form here figured is lilac-coloured, with a darker 
throat to the lip. 
As regards culture little need be said, for it succeeds under the treat- 
ment given to other Mexican Lelias. It is sometimes grown on a block 
but a basket or shallow pan is preferable. Strong plants are very 
floriferous. 
CYPRIPEDIUM x WILLIAMSIANUM AND ITS ALLIES. 
THE question of the origin of Cypripedium x melanophthalmum and its 
allies was discussed in our last .volume (pp. 291, 348), and we have now 
received five more flowers from the collection of E. F. Clark, Esq., of 
Teignmouth. They aré C. x melanophthalmum, a seedling from C. 
X Harrisianum nigrum x venustum, agreeing well with the preceding, 
except for the absence of warts from the petals, C. X Williamsianum, C. 
'X Measuresianum, and another seedling form of C. x Violetta. Mr. 
Clark points out some resemblances between C. x Williamsianum and C. 
xX Measuresianum—which latter was unquestionably derived from C. 
villosuri and C. venustum, and remarks that there is no trace of C. 
barbatum in the flower of the former. C. x Violetta is also pointed out as- 
near the two preceding in its flower, and this was derived from C. venustum 
x Sallieri. Commenting on the resemblance between the three just 
C. villosum and C. venustum, as we formerly thought? In reply we can 
only say that the resemblance to C. X Harrisianum in the foliage, and 
through it to C. barbatum, can scarcely be meaningless, while the mark- 
ings on the leaves of C. Measuresianum are quite different. On the whole 
the evidence seems most in favour of C. x Harrisianum being one of the 
parents of C. x Williamsianum, and even the green veining of the dorsal 
sepal agrees better with C. x melanophthalmum than with C. X 
Measuresianum. : In any case the hybrid between C. venustum and C..

Williamsianum May yet appear. ~
