Botanical Magazine for June—The plants figured are Cattleya Rex, 
O’Brien (t. 8377) ; Columnea gloriosa, Sprague (t. 8387); Prostan- 
thera pulchella, Skan (t. 8379); Pteronia incana, DC. (t. 8380); and 
aussurea Veitchiana, Drummond and Hutchinson (t. 8381). 
Columnea gloriosa is a remarkably fine species, with its large, widely- 
open, scarlet flowers. It is a native of Costa Rica, and the plant 
from which the figure was drawn was purchased in 1909 from 
Messrs. Haage and Schmidt, of Erfurt. It is most nearly allied to 
C. microcalyz, Hanst., but is readily distinguished by its spreading 
calyx and the hairy, convex leaves from all other species in 
cultivation. 
The Prostanthera was presented to Kew by Mr. T. A. Dorrien- 
Smith, of Tresco Abbey, Isles of Scilly, in 1908, and we owe its 
introduction to Capt..A. A. Dorrien-Smith, who brought the plants 
with him from the Antipodes. It is a native of Australia, and a 
distinct, hitherto undescribed species which does not readily fall into 
any of the sections of this large genus. The small violet flowers 
and Boronia-like habit make it a worthy subject for cultivation in a 
cool house. 
Piteronia incana is a small grey-leaved glutinous South African 
shrub, The yellow flowers are borne in small axilliary capitula, and
