94 BULBS AND THEIR CULTIVATION, 



loses its leaves entirely except when in bad health. It is 

 specially liable to be infested with mealy bug, red spider, 

 and thrips, the remedies for which will be found else- 

 where. A mite also infests the roots. Increased by 

 offsets at potting time. 



The species and hybrids are as follows: Candida, grandi- 

 flora (Syn. amazonica), Mastersii, Sanderi, Stevensii, 

 Lowi, and Moorei. The two best are Candida and grandi- 

 flora. All are white-flowered, and grow about one to two 

 feet high. 



Eurycles. A genus of white-flowered bulbous plants, 

 natives of Queensland, and requiring hothouse culture. 

 They are somewhat similar to the Pancratiums, and flower 

 in spring. 



The bulbs require to be grown singly in 6, 8, or lOin. 

 pots, according to size, in a compost of three parts loam, 

 one part leaf-mould, and plenty of coarse sand. Pot 

 firmly. February is the best time to repot. After potting 

 plunge the pots as advised for Eucharis, and keep the roots 

 well supplied with moisture. In autumn gradually with- 

 hold water, and keep nearly dry all the winter. The 

 temperature during the growing season should be 65 to 

 75 deg., and 55 deg. in autumn and winter. Increased 

 by offsets. 



The only species are Cunningharni and sylvestris, both 

 white-flowered and growing one foot high. 



Gesnera. The Gesneras are tuberous-rooted plants, 

 natives of South America, growing about a foot high, and 

 bearing tubular-shaped, brilliantly-coloured flowers at 

 various seasons of the year. Many of the kinds, too, have 

 attractively-coloured velvety foliage. They will all 

 succeed in an ordinary stove temperature. 



By potting at different periods of the year a long 

 succession of flowers may be obtained. Thus, tubers 

 potted and started to grow in March would flower in June ;
