will only be while exposed to the sun, closing at night, 

 and opening again with the influence of the sun's rays,) 

 is a great beauty. The rays of the flowers are bright 

 orange, and the centre dark purple. G. pavonia has 

 handsome foliage ; flower similar to G. ringens, except 

 the centre of the flower being spotted, and is thought 

 to be the finest, but does not flower so freely. G. hcte- 

 rophylla is of the same character, except the foliage, 

 which is variable, the colour orange and vermilion. 

 They are half shrubby dwarf growing plants, and during 

 the months of July, August, and September, are liable 

 to damp off at the surface of the earth, from the action 

 of heat, and too much water. Pots must be well drain- 

 ed, and the plants kept partially in the shade. Their 

 flowers are syngenesious, and about two inches in 

 diameter. 



Grevilleas, about thirty species. A few of them very 

 handsome in flower and foliage, among which are G. 

 punicea ; G. acanthi/olid, (beautiful foliage) ; G. concinna, 

 very pretty straw and rose-coloured flowers ; G. juni- 

 perina, green and straw-coloured; G. linearis, white 

 flowers. The flowers of the whole are curious, though 

 not very attractive. Some carry their flowers in race- 

 mose spikes, others on flowering branches, which are 

 recurved ; the petals are very small and rugged ; the 

 stile longer than the appendage. They grow freely, 

 flower and ripen seeds; all evergreen dwarf shrubs. 



Hakeas, about forty species, not generally so in- 

 teresting or attractive as the last genus ; flowers all 

 white ; construction similar to Grevillea, but the foliage 

 more varied. H. gibbosa, H. nitida, H. saligna, H. sua-
