tinctive characters. The plant is much more like N. 

 leucantha. Indeed, in flower it is somewhat of a miniature 

 form of that species. It differs from it, however, in foliage 

 and other points, and is probably the N.E. Yunnan repre- 

 sentative of this Mid. West Yunnan species. The following 

 is a description of the plant based upon Maire's specimens 

 in the Edinburgh Herbarium : — 



Nomocharis Mairei, Levi, in Fedde Repert. xii (1913), 287 

 (revised character). 



Stem as much as 35 cm. high with short internodes 

 about 3 cm. long fairly stout about 4 mm. in diameter 

 below the foliage-leaves. Foliage-leaves in whorls of 3-5 

 over the stem, below one or two single at the node followed 

 by a pair, coriaceous ovate-lanceolate shortly acuminate, 

 lower ones sometimes elliptic-ovate or ovate and obtuse, 

 about 3"5-4 cm. long (lower ones a little shorter), 1*3 cm. 

 broad (lower ones sometimes nearly 2 cm.). Flowers 

 terminal solitary or in a 2-flowered raceme white with 

 purple spots on petaline segments, rufescently blotched at 

 base, pedicel stout ascending or erect straight to slightly 

 deflexed tip, about equal in length to leaves. Perianth 

 widely open almost flat as much as 5*5 cm. across ; seg- 

 ments dissimilar more or less abruptly acuminate, tip 

 obscurely fringed ; calycine oval about 3 cm. long 1-5 cm. 

 broad unspotted but with a small dark blotch at base, 

 eglandular; petaline broadly ovate or rounded about 3 cm. 

 long 2*5 cm. broad, margin from below middle toothed 

 fringed, below entire, midrib prominent, with a bilobed 

 basal gland, one lobe on each side of midrib, each lobe 

 bearing a fan-shaped much incised fringed lip. Stamens 

 about 1'2 cm. long; inflated lower part of filament about 

 6"5 mm. long about equalling ovary, subulate portion about 

 3 mm. long; anther barely 5 mm. long, dorsifixed about 

 1'5 mm. above base, shortly apiculate.
