 to white. It is a pretty addition to our hardy annuals. 



127. ARGYREIA /estiva. Wallich plantae asiaticae 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. 



129. EPIDENDRUM (Encyclium) articulatum. Klotzsch in Allgemeine Gar- 

 tenzeitung, Sept. 22, 1838. 



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. 



130. LINDENIA rivalis. Bentham Plantse Hartwegianse, p. 84. no. 581. 



Under this name Mr. Bentham has proposed a new genus 

 of Cinchonaceous plants, resembling Tocoyena in the form of 

 the flower, but corresponding with Augusta or Portlandia in
