Sept."] GREEN-HOUSE HOLLAND BULBS. 289 



five-inch pot, giving very little water till they begin to 

 grow. They will all keep in good pits, as well as in the 

 green-house. (Soil No. 11.) 



Sparaxis. We are enraptured with this beautiful genus 

 of small bulbs, closely allied to Ixia, but more varied in 

 colour. S. grandiflora striata is striped with purple and 

 white. S. versicolor, colours crimson, dark purple, and 

 yellow. S. tricolor, yellow, black, and scarlet. S. albida, 

 large white, with black spots. S. caelestis, bluish purple. 

 S. sulphured, yellow. S. purpiirescens, purple. Treat as 

 Oxdlis. (Soil No. 11.) 



Tritonia, a genus of about twenty-five species. Few of 

 them deserve culture in regard to their beauty. T. crocata 

 is in our collections as 7. crocata, which is among the 

 finest, and T. zanthosplla has white flowers, curiously 

 spotted with yellow. (Soil No. 11.) 



Watsonia, a genus containing several species of showy 

 flowers, several of which are in our collections under the 

 genus Gladiolus, but the most of the species may be dis- 

 tinguished from it by their flat shell-formed bulbs. W. iri- 

 difolia is the largest of the genus, and has flowers of a flesh 

 colour. W. rosea is large growing, the flowers are pink, 

 and on the stem in a pyramidal form. W. humilis is a 

 pretty red flowering species. W.fulgida, once Antliolyza 

 fidgens, has fine bright scarlet flowers. W. rubens is an 

 esteemed red flowering species, but scarce. (Soil No. 11.) 



These genera of bulbous plants are in general cultivation. 

 There are, no doubt, some splendid species that have not 

 come under our observation, and others which may be ob- 

 tained from the Cape of Good Hope and China that are 

 not known in any collection, all of which would be per- 

 fectly hardy in our southern states. Bulbs generally re- 

 quire very little water until they begin to grow ; then sup- 

 ply moderately, and keep them near the light. Of the 

 Holland or Dutch bulbs, the Hyacinth is the favourite to 

 bloom in the green-house. A few of the Tulip, Narcissus, 

 Iris and Crocus, may, for variety, be also planted with any 

 other that curiosity may dictate. When these are grown in 

 pots, the soil should be four-eighths loam, two-eighths leaf 

 mould, one-eighth decomposed manure, one-eighth sand, 

 well compounded ; plant in pots from five to seven inches, 

 keep the crown of the bulb above the surface of the soil,
