NEW, RARE, AND BEAUTIFUL ORCHIDS OF COSTA RICA. 7 
parviflora. The most important feature of 
the two varieties is that they are both au- 
tumn-flowering. Between themselves the 
distinction is rather insignificant, Parviflora 
having smaller flowers, and Autumnalis hav- 
ing the throat of the lip whitish. Culture is 
-nearly like that of the typical form, but the 
same heat as Bowringiana. 
CG. Skinneri alba. — There are two pure-white 
forms, one with yellow, the other with rose- 
colored throat of the lip. They are no longer 
found in a wild state, and the richer people 
here love the ‘* Guaria blanca” with such en- 
thusiasm that the few private people whoown 
plants of the same would not sell them for any 
price. In fact, 1am almost thinking of buy- 
feature, covering, aS it does, sometimes the 
fences on both sides of the road with its bright 
crimson spikelets. There is a more robust 
form that seems constant. The last time 
when I sent out for it, I was told that it had 
disappeared from most places. Grow it on 
the bare block, near the light, with heavy 
watering in Summer and rest in winter.

CRYPRIPEDIUM CAUDATUM. (Reproduced from a photograph.) 
Chysis. 
Ch. aurea.—Grows on the higher mountains, be- 
ing of the few Orchids found at the bottom of 
the deep valleys, where it grows alongside 
the water-streams, always on the white, soft 
bark of a certain tree, hanging head down. 
Cool, intermediate, good shade, best on cork. 
Bulbs don’t stand the least shriveling. 
Celia. 
One species found here; too rare to be offered. 
Comparetia. 
C. faleata.—Although a small plant, yet it gives 
in certain places to the landscape a singular 
plants which abounds in variation of forms to 
such an extent as do the Orchids; and among 
this capricious family, perhaps the most orig- 
inal member is Cypridedium caudatum, the 
long-tailed Lady-slipper. Every amateur 
knows it; not the smallest collection is with- 
out it. In every book on Orchids it is enthu- 
Siasticaly described and recommended. I 
therefore have nothing more to add, except 
the fact that the form I exclusively offer is 
the true rose-colored variety. Its culture is 
easy. Although growing on the top of the 
highest oaks, it seems to delight in the com- 
post applied to the so-called ‘‘terrestrial’’ Or- 
chids. The plants stand much shade; but to
