207. SALVIA prunelloides. Humboldt, Bonpland, & Kunth, nova genera 
et species plantarum, vol. 2. 289. Bentham, Labiate, p. 256. 
This plant has been raised by Mr. Martin Mayes, of the 
Durdham Down Nursery, near Bristol, from roots received 
about three months since from Mexico. It was found in 
New Spain, by Mocino and Sesse, and also by Karwinski ; 
Humboldt and Bonpland met with it on rocks upon the sides 
of the volcanic mountain Jorullo. Mr. Mayes informs me 
that its roots are tuberous and about the size of a small 
walnut; he adds, that the plant does not grow more than 
from six to eight inches high, and that he thinks it would be 
suitable for bedding out in summer, when it would form a 
good contrast with Verbena Melindres. The flowers are 
blue. 
208. POLYSTÁCHYÁ cerea; pseudobulbis ovatis, foliis oblongo-linearibus 
undulatis racemo simplici obtuso brevioribus, floribus cernuis, labelli 
trilobi pone basin callosi per axin pubescentis lobis lateralibus nanis in- 
termedio obtuso undulato. 
A small species, imported from Oaxaca by Messrs. Lod- 
diges (265). The flowers, when full blown, have the colour and 
texture of old wax ; they are distinetly drooping and arranged 
in a very dense obtuse raceme about an inch long. In habit, 
size, and general appearance the species bears much resem- 
blance to the Encyclia nana of Poppig, which, like the 
E. polystachya of that author, is apparently a species of 
Polystachya, notwithstanding the manner in which the pollen- 
masses are represented, about which I think there must be 
some error. In this plant there is a pair of pollen-masses, 
excavated at the back, and attached to a short caudicula and 
small gland. 
209. ERIA velutina (G. Loddiges in litt.) ; caule tereti velutino, foliis dis" 
tichis carnosis ovato-lanceolatis margine revolutis junioribus utrinque 
velutinis adultis suprà glabris, flore solitario oppositifolio inter squamas 
herbaceas obtusas villosas sessili, sepalis petalisque linearibus apice 
recurvis extus hirsutis, labello cuneato elongato canaliculato apice rotun- 
dato subtrilobo supra pubescente inappendiculato. 
A singular plant of no beauty, brought to Messrs. Loddiges 
from Sincapore by Mr. Cuming. It has pale dirty yellow 
flowers, growing singly among hairy bracts opposite the leaves. 
It is probable that Wallich's Dendrobium vestitum, of which 
I have seen only fragments of flowers, is a species of Eria
