DENDEOBIUM. 163 



D. formosum giganteum. — A magnificent variety of the pre- 

 ceding, much stronger in growth, and, like it, evergreen. The 

 flowers, which are produced at the top of the stems, measure 

 from four to five inches across ; colour snow white, with 

 bright yellow on the centre of the lip ; it requii'es the same 

 treatment as D. formosum, and remains in bloom about the 

 same time. I have seen several fine specimens of this plant, 

 some with as many as twenty- one leading growths, which, 

 when in bloom, make a fine display. I saw this particularly 

 fine in the gardens of the Duke of Sutherland at Trentham 

 Hall, grown by Mr. Stevens. Native of Moulmein. 



D. Gihsoni. — A very pretty evergreen erect-growing Orchid 

 from India, about two feet high ; the blossoms are produced 

 on the ends of the old bulbs ; the sepals and petals are rich 

 orange; the lip bright yellow, with two dark spots on the 

 upper part. It blooms during the autumn months, lasts two 

 weeks in good condition, and requires the same treatment as 

 D. formosum. 



D. GriffitJdmmm. — This is certainly one of the most glorious 

 of the yellow spring-flowering Dendrobes ; it is about double 

 the size of D. densiflorum in all its parts, and its immense 

 drooping spikes of bloom are of the richest golden yellow, 

 and remain in perfection for a long time. This plant is very 

 rare, and varieties are often sold for it which are much inferior 

 to the true plant. 



D. Heynecmum. — A charming deciduous species from 

 Bombay, which grows eight inches high, and produces spikes 

 of white flowers from the tops of the stems at difierent times 

 of the year ; they have somewhat the appearance of sprigs of 

 whitethorn. It is best grown on a block, with a moderate 

 supply of moisture, during the growing season. It continues 

 about ten days in perfection. 



D. hedyosmum. — This beautiful sweet-scented Orchid is
