seven inches long, three-quarters to one and a quarter broad 

 deeply channelled above, very coriaceous, strongly keeled at 

 the back, the keel increasing in size towards the tip, where 

 it forms an angular projection ; tip of the leaf abruptly trun- 

 cate and two-lobed, the lobes ending in rigid angular points. 

 Racemes many, axillary, pendulous, five to seven inches long, 

 on peduncles of equal length, green, with one or two small 

 appressed sheaths ; peduncles spreading, together with the 

 slender ovaries one and a quarter inches long, a slightly redder 

 lilac than the rest of the flower. Flowers one to one and 

 one-third inch diameter ; sepals and petals subequal, spreading, 

 incurved, rather undulate or twisted, obovate-spathulate, 

 subacute, pale blue-lilac inside, rather darker outside. Zip 

 rather smaller than the petals, three-lobed ; two lateral lobes 

 small, dark blue, adnate to the sides of the very short dark 

 blue column; mid-lobe projecting, between obovate and 

 cuneate; margins deflexed, of the same colour as the petals; 

 tip rather dilated, rounded, notched ; disk violet-blue, with 

 two thick, smooth, obtuse ridges, and a short basal inter- 

 mediate one ; spur shorter than the lip, incurved, subacute, 

 blue-hlac ; anther yellow. — J. D H.
