of the family given in part 2 of the " Nachtrag " to Engler and Prantl's 

 " Natui'lichen Ptianzenfamilien," it appears that sixteen genera, with about 

 seventy-five species, are now known. The distribution of the family is 

 mainly tropical; but it stretches northwards as far as China and Japan in 

 the Old World, and Virginia in the New. It attains its southern limit in 

 Mew Zealand and Tasmania. The genus Bagnisia, in which I have placed 

 Mr. Hill's plant, contains three other species — one from Borneo, one from 

 Java, and the third from New Guinea. 



Bulbophyllum tuberculatum, the second species figured on the accompany- 

 ing plate, is a charming but little-known plant. It was first described by 

 Mr. Colenso in 1884, from specimens collected by Mr. A. Hamilton at Petane, 

 Hawke's Bay. At a later date Mr. Hamilton also gathered it in woods near 

 Palmerston North. It has since been found near Kaitaia by Mr. R. H. 

 Matthews, in the Lower Waikat'o by Mr. Carse, in the East Cape district 

 by Mr. L. Wall, and near Collingwood by Mr. Dall. In all probability it is 

 not uncommon in forest districts in the North Island and the northern 

 portions of the South Island; but as it is principally found on the upper 

 branches, of tall forest-trees it is not at all easy to detect its presence. 

 Although agreeing in habit with B. pygmceiim, it differs in the larger size, 

 2-4-flowered peduncles, and larger flowers with a bright orange-red lip. The 

 lip of B. pygmcetiiri is always white.

 inside of the perianth-tube ( x 8) ; 9, the same seen from the other side, showmg the anther-cells 

 (x 8) ; 10, a single stamen with dehisced anther-cells (x 8) ; 11, stigma (x 6) ; 12, section of ovary, 

 showing the three parietal placentas and the numerous ovules (x 6).
