j. RIVEA tilicefolia. Choisy Convolv. orient, p. 25. 



This large half shrubby climber, from Ceylon, has lately 

 flowered in the garden of His Grace the Duke of Northum- 

 berland at Syon. It appears to be a native of various parts 

 cf the world, for M. Choisy names not only the continent 

 and islands of India, but also the Isle of France, Cape of 

 Good Hope, the West Indies, and Peru, as stations from 

 which specimens of it have been brought. It has leaves much 

 like those of the Lime Tree in form, but thinner. Its flowers 

 are very large, light purple, and single in the axils of the 

 leaves. It is perhaps too strong a twiner for trellis cultiva- 

 tion, but is an ornamental plant where there is room for it to 

 spread. It is the Convolvulus tilicefolius of some botanists, 

 the Ipomcea tilicefolia of others, and the C. gangeticus of 

 Roxburgh, who speaks of it as an inhabitant of the banks 

 of the Ganges, where it blossoms in the cool season, when 

 its extended branches and numerous very large bright pink- 

 coloured flowers are highly ornamental. 



30. ACACIA bijfora. R. Brown hort. Kew. 5. 463. DeCand. Prodr. 2. 449. 



A pretty little greenhouse shrub, with small axillary heads 

 of yellow flowers smelling like Hawthorn. It was raised by 

 Messrs. Lowe and Co. from Swan River seeds. The false- 

 leaves have a very unusual form ; they may be described as 

 wedges, with one of the angles mucronate and more taper- 

 pointed than the other, and with the midrib carried into the 

 longer angle, the effect of which is to give these parts a 

 singularly oblique appearance, and to make them look hunch- 

 backed. 



31. STANHOPEA aurea. G. Loddiges, 



Imagine a plant whose flowers have the size of S. insignis, 

 the form of S. venusta, the smell of S. oculata, the colour 

 of Maxillaria ai'omatica, and are arranged in a spike two 

 feet long, and the reader will have a tolerably distinct con- 

 ception of this beautiful thing, which Messrs. Loddiges re- 

 ceived from Mr. Bateman, who obtained it from Guatemala. 

 It has the two dark spots of Stanhopea oculata, but they are 

 in some manner lost in the flood of yellow that surrounds 

 them.
