302: "WILSON EXPEDITION TO CHINA 
FORSYTHIA Vahl. 
Determined by ALFRED REHDER. 
Forsythia suspensa Vahl, Enum. I. 39 (1804).— Siebold & Zuc- 
carini, Fl. Jap. I. 12, t. 3 (1835). — Hemsley in Jour. Linn. Soc. 
XXII. 82 (1889). 
Syringa suspensa Thunberg, Fl. Jap. 19 (1784). 
Lilac perpensa Lamarck, Encycl. Meth. III. 513 (1788). 
Forsythia Fortuni Lindley in Gard. Chron. 1864, 12. 
Western Hupeh: Hsing-shan Hsien, thickets, moors and cliffs, 
alt. 300-1000 m., May and September 1907 (No. 637, in part); near 
Ichang, cliffs, alt. 300-500 m., June 11, 1907 (No. 637, in part); 
Chang-yang Hsien, thickets, alt. 600-1200 m., May 1907 (No. 637, 
in part). 
Wilson’s specimens differ somewhat from the cultivated Chinese form (F. sus- 
pensa, var. Fortunei Rehder) in the intense purple color of young branchlets and 
the purplish hue of the young unfolding foliage. 
Forsythia suspensa, f. pubescens Rehder, n. forma. 
A F. suspensa, var. Fortunei recedit foliis utrinque et petiolis mol- 
liter pubescentibus. Ramuli glabri, hornotini purpurei; folia ellip- 
tico-ovata, saepissime trifoliolata. 
Raised with the typical glabrous form at the Arnold Arboretum from seed eol- 
lected by Wilson and distributed under No. 637.* 
1 Another Chinese form which seems to merit a distinctive name is the following: 
Forsythia suspensa, var. latifolia Rehder, n. var. 
Shantung: Po-shan, very rare, September 1907, F. N. Meyer (No. 263). 
A typo recedit foliis late ovatis omnibus simplicibus (semper?) acutis, basi rotun- 
datis, grossius serratis, inferioribus saepe apice rotundatis basi fere subcordatis, 
3-6 cm. longis et 2.5—4.5 cm. latis, capsulis latioribus, 15-18 mm. longis et 8-10 mm. 
latis, brevius acuminatis. 
This variety resembles in its always, or at least mostly, undivided leaves F. sus- 
pensa, var. Sieboldii Zabel, but it seems to be a more robust, upright growing shrub.
