13. Oncidium iridifoliim, Pigmy Oncidium. (Bot. Reg., 1611.) Orchi- 

 daceae ; Gynandria ; Monandria. A very curious species, the foliage being scarce 

 an inch and a half long, and the flower stem little more than two inches high. 

 The flowers are very neat and pretty ; yellow, streaked with red ; each flower is 

 about three parts of an inch across. It has bloomed profusely under the skilful 

 management of our friend Mr. Cooper, at Wentworth House Gardens. It is a 

 native of Mexico, and in its native habit, is found to grow exclusively upon the 

 branches of Orange and Lemon trees, and constantly prefers a dry situation, and 

 to be exposed to the sun. 



14. Onobryches radiata, Radiated. (Birm. Bot. Gard., 3.) Leguminosie; 

 Diadelphia; Decandria; Synonym, Hedysaram Buxbauinii. The plant is a na- 

 tive of Caueasus. It is perfectly hardy, glowing two feet high. It is a perennial 

 plant. In its native situation it inhabits hilly parts of rocky districts. The flowers 

 are produced on cylindrical spikes, they are of a pale yellow colour ; the standard 

 is also marked with red lines, and has a yellow spot. The plant has recently 

 bloomed in the Birmingham Botanic Garden. It was raised there from seed pre- 

 sented by John Hunneman, Esq., in 1834. It delights in a light and dry soil.
