ROSACEAE. — SPIRAEA 453 



Yunnan: Mengtze, south-western mountains, alt. 2000 m., A. Henry (No. 

 9280; shrub, 2 m. high). 



The spreading foUiclcs, which are not upright as in the type, and the very dense 

 and closely serrate leaves give to this plant a very distinct appearance, and when 

 the flowers are known, it may possibly prove to be a distinct species. 



Spiraea Fritschiana Schneider, III. Handb. Laubholzk. I. 477 (1905). 



Spiraea japonica, var. typica Gilg in Bot. Jahrb. XXXIV. Beibl. LXXV. 39 

 (non Thunberg) (1904). 



Western Hupeh: Hsing-shan Hsien, roadsides, moist places, alt. 

 1000-1300 m.. May 1907 (No. 2750; bush, 1-1.25 m. high); without 

 precise locality, June 1900 (Veitch Exped. No. 987). Shensi: Kin- 

 ten-shan, July 14, 1897, G. Giraldi: "Kan-y-san, Lao-y-san," June 

 11-12, 1897, G. Giraldi. Shantung: Tsingtau, 1901, Zimmerman 

 (No. 382). 



This species seems most closely related to S. betulifolia Pallas; the flowers are 

 apparently white, about 7-8 mm. in diameter; the disk is conspicuous, annular and 

 crenate at the margin; the stamens are much longer than the petals; and the carpels 

 are villose; the outside of the calyx and the inflorescence are quite glabrous and 

 usually purplish like the young branchlets. Probably Forbes' specimens from Chifu, 

 referred by Hemsley to S. betulifolia, belong to this species. 



Spiraea Fritschiana, var. angulata Rehder, n. var. 

 Spiraea angulata Schneider, III. Handb. Laubholzk. I. 477 (1905). 



Western Hupeh: Changlo Hsien, side of streams, alt. 1000-1700 

 m., June 1907 (No. 2749; bush, 1.25-2 m, high, flowers pink and white). 

 Shensi: Tai-pei-shan, 1910 Wm. Purdom (Nos. 1, 3); "Lao-y-san," 

 June 4, 1897, J. Giraldi: " Ta-sce-truen," September 18, 1897, J. 

 Giraldi. Shantung : Tsingtau, Zmmermanw (No. 344). Shinking: 

 Tsien-shan, June 7, 1906, F. N. Meyer (No. 92). Korea: "Mt. des 

 Diamants," June 22, 1901, U. Faurie (No. 312). 



This variety differs from the type in its glabrous leaves which vary in shape from 

 broadly ovate and subcordate at the base, as in the original specimen of »S. angu- 

 lata, to oblong-elliptic; No. 344 from Tsingtau is represented in the Arnold Arbo- 

 retum Herbarium by two branches, one with subcordate and broadly ovate leaves, 

 the other with elliptic and cuneate leaves, both about 4-5 cm. long; No. 2749 from 

 Hupeh is also represented by two branches, one with elliptic leaves 3-4 cm. long, 

 the other with elliptic-oblong leaves 7-10 cm. long. The fact that the pubescent 

 and the glabrous form are found together at Tsingtau and appear again both in 

 Hupeh and Shensi, is a further proof that they are only varieties of one species. 

 The specimen from Shingking resembles the type of this variety in its distinctly 

 ovate leaves, but they are rounded and inclined to be broadly cuneate, never sub- 

 cordate at the base, and do not exceed 3.5 cm. in length. The specimen from Korea 

 differs more widely in its oblong or elliptic-oblong and nearly doubly serrate leaves.
