242 GREEN-HOUSE REPOTTING. [March. 



when the flowers are fully expanded, (which 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 foli- 

 age ; flower similar to G. rlngens, except the centre of 

 the flower being spotted, and is thought to be the finest, 

 but does not flower so freely. G. heterophylla is of the 

 same character, except the foliage, which is variable, the 

 colour orange and vermilion. They are dwarf-growing 

 plants, and during the months of July, August, and Sep- 

 tember, are liable to damp off' at the surface of the earth, 

 from the action of heat and too much water. Pots must be 

 well drained, and the plants kept partially in the shade. 

 Their flowers are syngenesious, and about two inches in 

 diameter. (Soil No. 9.) 



Grevilleas, about thirty species. A few of them very 

 handsome in flower and foliage, among which are G. puni- 

 cea ; G. acanthifolia, (beautiful foliage ;) G. concinna, very 

 pretty straw and rose-coloured flowers ; G. juniperlna, 

 green and straw-coloured ; G. linearis, white flowers. The 

 flowers of the whole are curious, though not very attrac- 

 tive. Some carry their flowers in racemose spikes, others 

 on flowering branches, which are recurved ; the petals are 

 very small and rugged; the stile longer than the append- 

 age. They grow freely, flower and ripen seeds ; all ever- 

 green dwarf shrubs. (Soil No. 1.) 



Habrdnthus, about ten species of small South American 

 bulbs, nearly allied to Amaryllis. H. jlndersonii, H. 

 versicolor, H. Candida, and H. robusta, are fine ; they are 

 in colour yellow, blue, white, and lilac. We have very 

 little doubt but these bulbs will do to plant out in the garden 

 in April, and be lifted in October. Keep them from frost. 

 Thus treated, they are very desirable. (Soil No. 12.) 



Hdychrysums, above forty species, chiefly belonging to 

 the green-house, all everlasting flowers. H. grandiflbrum, 

 H. arboreum, H. fra grans, H. adoratlssimum, H. friiti- 

 cans, and H. fulgidum, are all very esteemed species, 

 mostly with soft downy foliage. The pots should be well 

 drained, and the plants kept in an airy situation, as they 

 suffer from the least damp. If the flowers are cut off be- 

 fore they fade, they will retain for many years all the
