 tatis glabris, antheris globosis; ovarium glabrum; styli recti, staminibus 

 breviores, glabri, stigmata obliquo pauUo incrassato. Capsula glabra,

Western Hupeh: Hsing-shan Hsien, margins of woods, alt. IGOO- 

 2300 m.. May, June and August 1907 (No. 184). 



From all other species C. platypetala is easily distinguished by the very broad 

 hatchet-shaped petals. It is perhaps nearest to C. hivialayana Griffith, which has, 

 however, differently shaped petals, a villose ovary and curved divergent styles; 

 the leaves, too, of the two species are very different. 



This new species is a common shrub in the thickets and margins of woods 

 throughout north-western Hupeh. 



Corylopsis platypetala, var. levis Rehder & Wilson, n. var. 



A typo recedit glandularum defectu, ramulis annotinis brunneis 

 v. fusco-brunneis, capsulis paullo minoribus leviter glaucescentibus. 

 Flores ignoti. 



Western Szech'uan: west and near Wen-ch'uan Hsien, thickets, 

 alt. 1300-2500 m., July and October 1908 (No. 1020, type); near 

 Mao-chou, Chiu-ting-shan, thickets, alt. 1600 m.. May 22, 1908 

 (No. 2272); Ching-chi Hsien, Ta-hsiang-hng, alt. 1300-2600 m.. May 

 1908 (2273); Mupin, thickets, 2000-2600 m., June 1908 (No. 2274). 



In the absence of flowers the characters which separate this variety from the 

 type are comparatively slight, but it occupies a different geographical range and 

 considering the fact that all species and varieties of this genus are rather local we 

 have thought it advisable to separate the Szech'uan plant from the type which 

 has been collected only in Hupeh. This plant is in cultivation, and when it flowers 

 its taxonomic rank can be more accurately determined. None of the Herbarium 

 specimens have any trace of glands, but the seedlings have a few stipitate glands on 

 the young shoots and petioles; glands probably occur more or less frequently on 

 all the species.
