DENDROBIUM. 181 



commonly grown under the name of D. macropJiyllum, which 

 proves to have been previously appropriated to the plant 

 hitherto known in gardens as D. Veitchianum. 



D. superbum giganteum. — A showy variety from Manilla, 

 which flowers in the same way as the preceding, and about 

 the same time. Flowers from five to seven inches across ; 

 sepals and petals beautiful rose purple ; the lip the same 

 colour, fringed and marked at the base with a pair of rich 

 purplish red spots, and they remain about two weeks in per- 

 fection. A fine plant for public exhibition, but it requires to 

 be kept in a cool-house to keep it back for that purpose, as it 

 generally blooms very early. 



D. superbum Huttoni. — This exceedingly rare and beautiful 

 variety has pure white sepals and petals, whilst the lip is the 

 colour of the normal form, saving a marginal border of white. 

 The rhubarb scent is not so decided as in the species. It 

 requires the temperature of the East Indian house, and is a 

 native of the Malayan Archipelago. 



D. Tattonianwn. — A very pretty Orchid from North Aus- 

 tralia ; it is of easy culture and sweet-scented. It seems to 

 be a small-growing species, attaining some three inches in 

 height, and it makes a flower-stem about a foot long ; the 

 sepals and petals are yellow and white, and the lip bluish or 

 mauve. It is a very singular and desirable small-flowering 

 species. 



D. taurinum. — A strong- growing species from India, often 

 attaining a height of five feet, with upright stems. The sepals 

 are pure white, and the petals reddish brown, curling and 

 spread out like the horns of a bull, whence the name ; lip 

 white, margined with purplish violet. It is best grown in a 

 pot in peat. We seldom see good plants of this species under 

 cultivation. 



D. thrysiflorum Walkerianum. — The finest variety I have
