430 GARDEN PLANTS. PART 



II. 



Boronia Crowea Correa Calodendron Diosma Barosma 

 Agathosma. 



The numerous species of these several genera, the three first 

 natives of New Holland and the remainder of the Cape, are 

 for the most part very ornamental shrubs, producing beautiful 

 flowers, and much cultivated in green-houses in Europe, but not 

 a single one is to be met with in this country, nor is it at all 

 probable would be able to exist in the climate. 



Dictamus. 



D. Fraxinella. This old familiar, fragrant-leaved plant of the 

 English gardens is altogether unknown here. 



Ruta. 



1. R. angustifolia EUE. The prettily-formed hoary-green 

 foliage of this small well-known herb forms a pleasing variety 

 amongst other pot-plants ; bears in the Cold season greenish- 

 yellow uninteresting flowers. Propagated by division. 



2. R. graveolens. The Common Eue of the English gardens, 

 between which and the last the difference is not very perceptible, 

 is, I believe, not met with here. 



SIMABURACE^J. 

 Quassia. 



Q. amara. A tree in Surinam, its native locality, of consider- 

 able size ; grows here to not more than about seven feet high, 

 and is regarded as one of the choicest, as it certainly is one of 

 the most beautiful, plants of our Indian gardens ; leaves un- 

 equally pinnate ; leaflets obovate, four inches long more or less ; 

 leafstalks with wide, crimson-tinged wings ; bears in April and 

 May terminal racemes of erythrina-like bright crimson-scarlet 

 flowers. Propagated by gootee, as well as by cuttings, under a 

 hand-glass in sand. 



ZYGOPHYLLACE^l. 



Tribulus. 



1. T. lanuginosus. A low trailing plant with pinnate leaves; 

 bears nearly always large bright-yellow sweet-scented flowers.
