GREEN-HOUSE REPOTTING. 257 



tained by cutting transverse incisions in the bark. P. 

 vera and P. reticuldta are good species ; leaves pinnated ; 

 leaflets ovate, lanceolate ; easily cultivated. (Soil No. 2.) 



Pittosporums, about nine species, with handsome foli- 

 age, and small white flowers in clusters, which are fra- 

 grant. P. toblra is a native of China, and nearly hardy ; 

 leaves lucid, obovate, obtuse and smooth; there is a beautiful 

 variegated variety of it. P. undulatum, P. coridceum, P. 

 revolutum, P.fulvum and P.ferrugineum, are very orna- 

 mental evergreens, and will grow with the most simple 

 treatment. (Soil No. 13.) 



Platylobiums, Flat Pea, four species of fine free-flower- 

 ing plants ; flowers leguminose ; colour yellow. P. for- 

 mosum, P. ovdtum and P. trianguldre, are the best; the 

 foliage of the former two is cordate, ovate ; the latter has- 

 tate, with spiny angles. (Soil No. 6.) 



Plumbagos, Lead-wort. There are only two species of 

 any consequence belonging to the green-house, P. tristis 

 and P. capensis. The former is a shy flowerer, but the 

 latter flowers freely ; colour beautiful light blue, and flow- 

 ers in spikes ; foliage oblong, entire, and a little glaucous ; 

 of very easy culture, and continues in bloom a considerable 

 time. (Soil No. 1.) 



Podalyrias, about fourteen species of pretty Cape shrubs; 

 foliage oblong, obovate and silky-like ; the flowers legumi- 

 nose ; colour blue or pink. P. sericca, P. styracifolia, P. 

 coruscans, P. argentea, P. liparioides and P. subiflora, 

 are the finest and most distinct species, and flower abun- 

 dantly. (Soil No. 6.) 



Proteas, about forty-four species. The foliage of this 

 genus is very diversified ; flowers very large, terminal ; sta- 

 mens protected by an involucrum , many -leaved and imbri- 

 cated ; which is very persistent. P. cynaroides has the 

 largest flower, which is purple, green and red. P. spe- 

 ciosa, P. umbondlis, once P. longifolia, P. melaleuca, P. 

 grandiflora, P. coccinea, P. cenocdrpa, P. pollens, P.for- 

 mosa, P. magnified, P. speciosa riibra, and P. melfifera, 

 will afford a very good variety. It is almost impossible to 

 describe their true colour, it being so various ; red, white, 

 straw, brown, green and purple, are most predominant, and 

 frequently to be seen in the same flower. The plants must 

 be well drained ; and during warm weather be careful that
