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

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

 yellow J 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 iu 

 good pits, as well as in the green-house. (Soil No. 11.) 

 Sparcixis. We are enraptured with this beautiful genus 

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

 color. S. grandifiora striata is striped with purple and 

 white. S. versicolor, colors crimson, dark purple, and yellow. 

 S. tricolor, yellow, black, and scarlet. S. albkla, large 

 white, with black spots. S. coslestis, bluish purple. kS. 

 sulphiirea, yellow, /i?. purpurescens, purple. Treat as Ox- 

 dlls. (Soil No. 11.) 



Tritbrda, 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. zanthosplla has white flowers, curiously spotted with 

 yellow. (Soil No. 11.) 



Watsbma, 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. IK iridi- 

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

 color. 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. W. fuhjida., once Antholyza fdhjens, 

 has fine bright scarlet flowers. W. ruhens 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 water until they begin to grow; then supply mode- 

 rately, and keep them near the light. Of the Holland or 

 Dutch bulbs, the Hyacinth is the fiivorite 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 arc grown in pots, the soil should
