III. Notes on Plants in PLA^'T Houses. By E. L. 

 Harrow. 



About 130 species of plants have flowered during June 

 in the plant houses of the Eoyal Botanic Garden. Of 

 these the majority have been natives of tropical countries, 

 and the houses devoted to these plants have, in conse- 

 quence, presented an attractive and interesting appearance. 



This being, ijar excellence, the growing season of orchids, 

 the least quantity of bloom is produced, and the plants 

 which have flowered have been chiefly species of Cypi^i- 

 pedium, Stanhopca, and Cattleya. 



The creepers upon the roof of the Palm House annexe, 

 and also in the corridor, include some showy species of 

 Allamanda, ClerocUnclron, and Solanum, etc., and these are 

 now becoming established and clothing the house. 



The following are a few of the most worthy of plants 

 flowered : — 



Lambertia formosa, Sm. This plant is a native of Aus- 

 tralia, and like many of the hard-wooded plants introduced 

 to cultivation during the end of the last and beginning of 

 the present century, is now rare in our gardens. The small 

 number of species representing the genus are all natives of 

 Australia ; the natural order to which they belong being 

 Proteaceae. The species under notice is of a shrub-like 

 habit, the branches springing from below the surface of the 

 soil, and bearing linear leaves generally in whorls of three. 

 The terminal involucres enclose seven flowers with a red 

 corolla, the lobes of which are reflexed and hairy, the style 

 protruding about an inch beyond the mouth of the corolla. 



Urcocharis Clihruni, Hort. This bigeneric hybrid was 

 raised by Messrs. Clibran, Altrincham, the parents being 

 Eucliciris grandijlora, Planch, and Linden, and Urceolina 

 pendula, Herb. It resembles most the fii-st-named in 

 foliage and in the colour of its flowers, but differs in the 

 flowers being produced in greater number on its inflor- 

 escences, and in its period of flowering. The umbels 

 consist of six or more white flowers upon an erect peduncle 

 rising well above the foliage. 



Tricliopilia Galeottiana, A. Eich., is a native of Mexico,
