Botanical Magazine for July. — The plants figured are Echium 



Perezii, Sprague (t. 8617); Polystacliya paniculata, Rolfe 

 (t. 8618) ; Meconopsis Trattii, Prain (t. 8G19) and lihododendron 

 concinnum, Hemsl. (t. 8620). 



The Echium is a striking species from the Island of Palma, 

 nearly allied to H. Wildpretii, H, H. W. Pearson. The leaves, 

 however, are decurrent to the base, and the thyrse is more lax 

 and the style arms longer than in that species. The flower colour 



is pale pink, while in E, Wildpretfi it is a pale red. The 



striking difference in habit is well seen in the photograph pub- 

 lished in K.n. 1914, pp. 266, 267. The species was introduced 

 to cultivation by Dr. G. V. Perez, of Teneriffe, in 1911. 



Polystachya paniciilata was discovered by Afzelius in Sierra 

 Leone, and considered by Swartz to be a Dendrohium. Its true 

 identity was only estal)iished when the type specimen was sent to 

 Kew from XJpsala in connection with the preparation of the 

 Plora of Troj)ical Africa. It has recently been found by Mr. 

 C. B. Ussher in the Mabira Forest, Uganda, and its introduction 

 13 due to the late Sir Trevor Lawrence, whose son, Capt. C. T. 

 Lawrence, sent plants from West Africa. The orange-red flowers 

 borne in dense panicles are very striking. 



Meconopsis Prattii was originally included first tinder M- 

 sinuata, Prain, and -then under M. rudis, Prain, but fuller 

 material has shown it to be a distinct species. It is distinguished 

 by its herbaceous foliage, shorter 'flowering pedicels, white 

 stamens and pale green stigma. A native of Szechunn and Kansu 

 at elevations of 13,000-15,000 ft., its introduction is due equally
