127. ARGYREIA festiva. Wallich plante asiaticee rariores, vol. i. p. 68. 
t:-76. 
This species has been obtained from India by His Grace 
the Duke of Northumberland. It is a large shrubby stove 
climber, with shining ovate leaves, clothed with fine brown 
silky hair on the under side. The flowers are pure white, 
and divided into five sharp rays, but they do not appear likely 
to be very showy, since they are small for a Convolvulaceous 
plant, and in the specimen which flowered at Sion, formed small 
cymes, but little branched. Possibly, however, this may im- 
prove as the plant gets stronger; in Dr. Wallich’s figure the 
flowers are represented as forming a loose panicle, and if this 
habit should be gained the plant will become much more showy. 
According to M. Choisy this species is a native of China, and 
the same as Argyreia acutifolia of Loureiro. 
128. EPIDENDRUM (Encyclium) pterocarpum. Lindley in Hooker’s Jour- 
nal of Botany, vol. 3. p. 82. : 
A singular species from Mexico which has lately flowered 
with Mr. Barker. It has a long thin raceme of pinkish 
yellow flowers, and a heart-shaped lip streaked with crimson. 
It is remarkable for the seed-vessel, when ripe, being extended 
into three broad sharp wings.

_ ,_ This species has also flowered with Mr. Barker. It 
is in the way of Epidendrum pastoris, but it is readily known 
by its lip having the middle lobe furnished with a triple 
row of tubercles, among which are intermixed many small 
projections.
