70 MISSOURI BOTANICAL GARDEN. 
f. saLiciFoLiA, Dippel, /. c.f. 177 (1889). 
Leaves oblong to lanceolate. As I have seen no speci- 
mens of this form and Dippel’s description is insuffi- 
cient, it seems doubtful whether it belongs here. 
f. STIPULIGERA, Sommier, N. Giorn. Bot. Ital. 22: 217 
(1890). 
Characterized by well developed stipular appendages.

Spreading shrub with reddish-brown slender branches, 
small leaves, 1.5-3 cm. long, setosely ciliate and slightly 
pubescent at first, and rather small slender flowers. 
Turkestan (Regel!).— Sometimes cultivated, as are the 
two following forms (Arnold Arboretum, Muenden, etc.). 
The two following forms seem to be closely allied, they 
differ by more upright growth and brighter reddish-brown 
branches; the first has the branches more brightly colored, 
and longer bluish-green leaves, the second has brighter 
green leaves and less slender flowers. Both forms were 
probably introduced from Turkestan.
