DENDROBIUM. 161 



and always to bear in mind that the red spider is its desperate 

 enemy, often attacking the leaves; this must be diligently 

 searched for, and, if found, kept under by syringing the 

 foliage every day, or even twice a-day, in summer. It makes 

 a splendid plant for exhibition. Native of Moulmein, &c. 



D. Devonianum. rliodoneurum. — This variety is said to last 

 longer in flower than the normal form. The sepals and petals 

 are streaked with dark purple ; lip large and round ; it is 

 remarkably sweet, and very distinct. Native of Moulmein. 



D. diocanthum. — A very pretty species from Moulmein ; it 

 is a very free grower and abundant flowerer, producing its 

 flowers, which are of two shades of yellow, in spring. 



D. Falconeri. — A magnificent plant, and one of the most 

 beautiful of the genus ; it is a pendulous grower, and so diffi- 

 cult to cultivate that only a few have succeeded well with 

 it. During the growing season it Ukes a good supply of water ; 

 but after it has finished growth, which is by autumn, it should 

 be kept rather dry till it begins to show flower, but must 

 never be allowed to suffer for want of water, as it frequently 

 grows during the winter months. Under this treatment it 

 flowers every year, well repaying any trouble that is taken to 

 induce it to produce its charming white and purple flowers, 

 which open in May and June, and remain about a fortnight 

 in perfection. One of the finest plants I ever saw of this 

 species was grown in a pine house with Messrs. Brooks & 

 Co., of Manchester : it had upwards of eighty very large 

 main stems. Native of Northern India. 



D. Farmeri. — A beautiful compact evergreen species from 

 India. The stems are terete at the base, thickening upwards, 

 and becoming clubbed and four-sided, supporting several lea- 

 thery dark green leaves. This grows and flowers in the same 

 way as D. densiflorum. Sepals and petals pink ; lip rich 

 yellow in the centre ; it blooms in April and May, and lasts
