62. BRASSIA pumila. 
B. pumila; folits binis patulis elongato-lanceolatis canaliculatis, sepalis 
lineari-lanceolatis acuminatis inferioribus labello longioribus, labello 
pandurato acuminato subundulato basi bicarinato dentibus ante carinas 
2 acutis elevatis aucto. 
This Brassia is remarkable for its dwarfness, as we learn 
from Mr. Barker who has flowered it from Mr. Linden's 
collections. It has pale yellow flowers stained with dull 
purple at the base of the petals; but there is no purple on 
the sepals, and the lip is very slightly tinted. It seems to be 
peculiar in the large size of the pair of somewhat transparent 
teeth whieh stand up in front of the two little customary 
ridges at the base of the lip; butit may be a variety of 
Br. Lanceana. Its aspect is, however, widely different. 
63. SALVIA pratensis. 
* Why is this species not cultivated here as a meadow plant ? 
Et forms a large portion of the hay in the north of Italy, in 
the Ionian islands, and in parts of Switzerland ; and, by the 
admixture of its deep blue flowers, with the red, yellow, and 
white, that prevail in our meadows, it adds much to their 
beauty, and affects the general aspect of the scenery. What 
are the peculiarities of soil and situation in which it delights, 
and are there any, which would prevent its being found useful 
here? I regret not having taken these points into considera- 
tion, while i was in the quarter where it flourished, and 
where it ceased to be frequently seen. From recollection I 
believe that the presence or vicinity of calcareous matter is 
the needful thing. It is indeed a subject deserving investi- 
gation, whether or not the neighbourhood of caleareous rocks, 
or their existence at a great depth below the. surface, in- 
fluences the vegetation, by affecting the springs, by electricity, 
or some other mysterious agency, where the presence of an 
extraordinary quantity of calcareous matter is not manifest in 
the soil. Climate does not materially interfere with the 
owth of Salvia pratensis, for it rises from the plain of 
Tubtardy into the valleys of the Alps, and is found amongst 
the stones on the mountains behind Trieste, as well as in the 
alluvial meadows by the salt pans, and very high amongst 
the rocks in Corfu and Santa Maura. It is superabundant
