FORSYTHIA Vahl. 

 Determined by Alfred Rehder.

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);

 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 purpUsh hue of the young unfolding foUage. 



Forsythia suspensa, f. pubescens Rehder, n. forma. 



A F. suspensa, var, Fortunei recedit foliis utrinque et petiolis mol- 

 liter pubescentibus. Hamuli glabri, hornotini purpurei; foha ellip- 

 tico-ovata, saepissime trifoliolata. 



Raised with the typical glabrous form at the Arnold Arboretum from seed col- 

 lected by Wilson and distributed under No. 637.i 



^ Another Chinese form which seems to merit a distinctive name is the following: 



Forsythia suspensa, var. latifolla 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 acimainatis. 



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.
