444 WILSON EXPEDITION TO CHINA 



et 7-15 mm. latis, sparsius et minus profundi serratis, minoribus fere 

 simpliciter crenato-serratis, umbellis minoribus 5-10-fioris. 



Western Szech'uan: Pan-lan-shan, west of Kuan Hsien, thickets, 

 rare, alt. 3600 m., June 24, 1908 (No. 2772; bush, 1 m., flowers white). 



Smaller in all the parts than the type, with nearly simply crenate-serrate leaves; 

 a very delicate looking form. 



Another variety, collected during the Veitch Expedition, is the following: 



Spiraea laeta, var. subpubescens Rehder, n. var. 



A tj'po recedit foliis densius et argutius inciso-serratis subtus laxe sericeo-pilosis, 

 inflorescentiis plerumque in apice ramulorum brevium 5-9-floris. 



Western Hupeh: Patung Hsien, April 1900 (Veitch Exped. No. 97). 



In the more closely and sharply serrate leaves this variety resembles S. anomala 

 Batalin, but that species differs in the glabrescent leaves truncate at the base, and 

 in its pubescent carpels.

Kiangsi: Ruling, thickets, common, alt. 1300 m., July 28, 1907 

 (No. 1718). Western Hupeh: north and south of Ichang, ravines, 

 etc., alt. 300-1000 m., April and December 1907 (No. 771); Hsing- 

 shan Hsien, thickets, alt. 1000-1300 m., May and December 1907 

 (No. 758); without locality, April 1900 (Veitch Exped. No. 67, flower- 

 ing specimen only). Fokien: April to June 1905, *S. T. Dunn 

 (Hongkong Herb. No. 2657). 



In the Hupeh specimens the pubescence is thinner and less fulvous than in the 

 Kiangsi and Fokien specimens. The cultivated plant resembles the specimens 

 from Kiangsi and Fokien.
