DENDROBIUMS. 89 



This will do either on a block, or in a pot with peat, and is 

 a desirable species. 



D. alba sanguineum. A charming new Orchid from India : 

 a compact-growing plant, with bulbs a foot high, and pro- 

 duces its large flowers, which are creamy white, from nearly 

 the top of the bulb, with a crimson blotch on the centre of 

 the lip. It blooms in July, and lasts a long time in perfec- 

 tion, and is best on a block, with moss. A scarce Orchid, and 

 a fine showy plant for exhibition. This is a difficult plant 

 to grow, so much so, that few people do it well. The best 

 plant I have seen of it was in the collection of T. Robinson, 

 Esq., Birkenhead, where it was growing on a block of wood, 

 in sphagnum, and seemed to be quite at home, for the bulbs 

 were very strong ; Mr. Atkinson, the gardener, informed me 

 that it required plenty of water during the growing season, 

 and that it liked the warmest house. 



D. album. From India. It produces its white blossoms 

 during the winter. This is not so handsome as many, but 

 it is worth growing where there is room, 



D. anosmum. A magnificent species from Manilla, which 

 grows in the way of macrophillum, but has better shaped 

 flowers, and no rhubarb scent ; the flowers which are large, 

 are produced in pairs down the stem ; colour beautiful rose, 

 and they last two or three weeks in perfection. Even now 

 this is a scarce plant, it blooms during the spring months, 

 and is best grown in a basket, as it is drooping and deci- 

 duous. 



D. calceolarea. A beautiful evergreen species from India: 

 This is a large-growing plant, about four feet high when 

 well grown : its flowers proceed from the top of the old 

 bulb, on a raceme, twelve or more together, which are 

 large ; sepals and petals bright yellow, lip same colour"; 

 it blooms during the summer months, lasting but four 

 days in bloom. This is best grown in a pot, with mosa 

 or peat.
