234 GREEN-HOUSE — REPOTTING. [March. 
G. simplex, G. sericea, G. imberbis, and G. pini/Clia, flower 
the most freely ; flowers straw colour, tubular, and corym- 
bose. G. simplex is sweet-scented, leaves small; the pots 
must be well drained, and care taken that they do not get 
either too wet or too dry, for the roots are very delicate. The 
plants must be kept near the glass, or they will be drawn 
weak. (Soil No. 6.) 
Gorteria persondta is the only species that belongs to this 
genus, and is an annual. There are several plants in our 
collections known as Gorterias, but which properly are Ga~d- 
nia, of which there are five species. G. ringens, when the 
flowers are fully expanded, (which will only be while exposed 
to the sun, closing at night, and opening again with the in- 
fluence of the sun's rays) is a great beauty. The rays of 
the flowers are bright orange, and the centre dark purple 
G. pavbnia has handsome foliage ; flower similar to G. rin- 
gens, except the centre of the flower being spotted, and is 
thought to be the finest, but does not flower so freely. G. 
lieteropliylla 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 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 drained, and the plants kept partially in 
the shade. Their flowers are syngenesious, and about two 
inches in diameter. (Soil No. 9.) 
Greiilleas, about thirty species. A few of them very 
handsome in flower and foliage, among which are G. jnoti- 
cea; G. acanthi/alia (beautiful foliage); G. concinna, very 
pretty straw and rose-coloured flowers; G. Junipcrinu, green 
and stra.w-coloured ; G. linearis, white flowers. The flowers 
of the whole are curious, though not very attractive. 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 appendage. They grow 
freely, flower, and ripen seeds; all evergreen dwarf shrubs. 
(Soil No. 1.) 
Ilithranthus, about ten species of small South American 
bulbs, nearly allied to Amaryllis. II Andcrsonii, II. versi- 
color, II Candida, and 77. robusta, arc 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
