September. .] OREEN-HOUSE HOLLAND BULBS. 2J 



ering tuberous species. 0. luxula alba, blush, white ; O. 

 nultiflbra, profuse flowering, white. 0. versicolor, striped. 

 0. dippii, lilac, which blooms in summer. 0. caparma, 

 yellow ; there is also a double yellow variety, though not 

 pretty; for a few others see last month. There should be 

 three or four bulbs planted in a 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.) 



Spardxis. We are enraptured with this beautiful genus 

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

 colour. 8. grandiflbra stridta is striped with purple and 

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

 low. S. tricolor, yellow, black, and scarlet. S. aliida, 

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

 sulphurea, yellow. S. purpurascens. purple. Treat as Oxc'dis. 

 (Soil No. 11.) 



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

 them deserve culture in regard to their beauty. T. crocdta, 

 is in our collections as /. crocdta, which is among the finest, 

 and T. zantliosp\la has white flowers, curiously 'spotted with 

 yellow. (Soil No. 11.) 



Watsbnia, 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. iridi- 

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

 colour. W. rbsea is large growing, the flowers are pink, and 

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

 red-flowering species. IF! fulgida, once Antliolyza fulacns, 

 has tine bright scarlet flowers. TF. 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 perfectly hardy 

 in our Southern States. Bulbs generally require very little 

 wafer until they begin to grow; then supply moderately, arid 

 keep them near the light. Of the Holland or Dutch bulbs, 

 (he Hyacinth is the favourite to bloom in the green-house. A 

 few of the Tulip, Nar -Assus, Iris and Crocus, may, for variety, 

 be ulso planted with any other that curiosity may dictate.
