ODONTOGLOSSUM MADRENSE. 
[PLate 71.] 
Native of the Sierra Madre of Mexico, 
Epiphytal. Pseudobulbs ligulate or narrowly-oblong, ancipital, three inches or 
more in length, pale green. Leaves lorate or linear-lanceolate acute, nervose, 
keeled, usually two but sometimes one only from the apex of each pseudobulb, 
sometimes with a leaf sheathing the base. Scapes lateral, twelve to eighteen inches 
long, bearing an inclined raceme of from six to eight flowers from the axils of 
brown membranaceous triangular acuminate bracts. Flowers fragrant, white blotched 
with reddish purple, three and a half to four inches in their vertical diameter, 
and somewhat less transversely; sepals lanceolate, acuminate, keeled behind, about 
two inches long, white, with an oblong bilobed reddish purple blotch at the base; 
petals broader, oblong, apiculate, white, with a bilobed purple blotch twice as long 
as that of the sepals and more distinctly separate; lip smaller than the sepals an 
petals, recurved, with a short hollow claw, which bears two small retrorse lateral 
lobes, having between them and in front two collateral pairs of retuse bipapulose 
i; the front lobe triangular or trowel-shaped, cuspidate, with crispy margins, 
white with the disk and alli orange-yellow. Colwmn short, greenish, wingless,

Our present subject, Odontoglossum madrense, is not only pretty but distinct, and 
very different in its growth, as well as in its flowers, from most of the Odontoglots, 
as will be seen by the accompanying figure, taken from the best grown specimen 
of the kind we have yet met with, which is in the select collection belonging » 
R. Vanner, Esq., of Camden Wood, Chislehurst, who certainly succeeds admirably in 
the cultivation of this plant. The subject from which our illustration was prepared, has 
flowered for two years in succession in the same grand way, and we have no saivot 
that as the plant gets more fully established it will produce more and more flowers on 
the spike. It is a very free-growing plant, but we find that it does best in a warmer 
temperature than that in which most Odontoglots thrive. The temperature of the . 
Cattleya house seems to suit it best, and it should be suspended from the roof, 
and grown in a shallow pan in a compost of peat and sphagnum moss. It requires 
a liberal supply of water during the growing season, and should not be kept ved 
dry when at rest, sufficient water being given to keep the soil moist, and t 
bulbs plump. We have also grown this plant successfully in the warm end 0 
the Odontoglossum house.
