brownish ; the labellum white, with the upper portion tinged 

 with purple. It appears to produce only a solitary flower at 

 a time." 



50. COB^EA stijmlaris. Bentliam plant. Hartweg. p. 45. 



This fine species has been raised in the garden ot the 

 Horticultural Society from Mr. Hartweg's Mexican seeds. 

 Its habit is that of the old Cobsea scandens, but it is appa- 

 rently more delicate, the leaves are narrower, of a paler and 

 brighter green, and the flowers are described as being yellow, 

 three inches long, obliquely inflated at the apex, and very 

 much contracted below the middle. It will doubtless prove 

 a summer climber ; but will not bear our winters. 



51. CLETHRA mexicana. DeCandoUe Prodr. 7. 590. Bentham plant. 

 Hartweg. p. 45. no. 341. 



An evergreen shrub or small tree from the colder regions 

 of Mexico, where it has been found by various collectors. 

 Mr. Hartweg sent home seeds, but they have not grown ; it 

 however exists in our gardens, having been raised by Messrs. 

 Loddiges. The leaves are obovate, very obtuse, about four 

 inches long, and white with down on the under side. Its 

 flowers appear from the dried specimens to be very like, and 

 quite as handsome as, those of Clethra arborea.

Bentham plant. Hartw. p. 52. no. 392. 



A verv fine lookino- Alder, from seeds of which, collected 

 in Mexico by Mr. Hartweg, at a place called Zacualtipan, 

 in the mountains between the city of Mexico and Tampico, 

 plants have been raised in the garden of the Horticultural 

 Society. It has fine oval acuminate leaves, from four to five 

 inches long, with veins prominent and downy on the under 

 side. Mr. Hartweg considered it a Birch, out it seems to 

 be an undoubted species of Alder. It may be expected to be 

 hardy. 



53. GARRYA laurifolia. Hartweg in Benth. plant. Hartweg. p. 14. no. 81. 

 This gives our gardens a new species of the curious hardy 



genus Garrya, of which Mr, Hartweg has discovered no 

 fewer than five during his travels in Mexico. A considerable 

 quantity of seed was given away by the Horticultural Society, 

 and it appeared to be in good condition ; from that however
