their hair with it. B. tremulum is also very curious, 

 possessing flowers with a peculiar sensitive hairy lip 

 resembling a hand brush. Very singular, too, is the 

 movable lip of such species as B. Lobbii> B. Deareii, 

 B. Siamense and B. Sillemianum. The labellum in these 

 cases is so constructed that with a very slight motion 

 it is thrown backward and forward as though it were 

 set upon a delicate hinge. B. Dayanum is characterised 

 by its hairy sepals, and B. Ericssonii by umbel-like 

 clusters of yellowish white flowers. 



B. grandijlorum produces large flowers, the upper sepal 

 being over four inches in length and quite two inches in 

 breadth, the lower sepals being beautifully reticulated. 

 It is a very remarkable plant, and is in fact the largest 

 flowered species known. It was originally discovered in 

 woods on the coast of New Guinea as long ago as 1848, 

 when it was first described and figured, but nothing 

 further was heard of the species until 1 895, when it was 

 exhibited at the Royal Horticultural Society of London. 

 Bulbophyllum Sanderianum is also remarkable and worthy 

 of more attention. Bulbophyllums generally thrive well 

 in the warmest house whilst growth is being made, but 

 they should be removed to the Cattleya house during the 

 resting period. The compact growing kinds should be 

 placed in well-drained shallow pans, and those of more 

 rambling habit in teak-wood baskets. The plants should 

 be suspended near to the roof glass, on the shady side 

 of the house, as they resent sunshine while appreciating 

 light. Plenty of water is essential whilst growing, but 

 when at rest less will suffice. Grow them in peat and 

 sphagnum. 



BURLINGTONIA 



The Brazilian Burlingtonias are beautiful dwarf-leafy 

 epiphytes, the best being B. fragrans and B. pubescens. 

 These may be grown in pans as advised for Bulbo-
