106 MISSOURI BOTANICAL GARDEN. 
Middle and South Europe: in the mountains from 
the Pyrenees to Bosnia (Bartling, Spenner, Berger, A. 
Braun, Knapp etal.). There are some rather scant Asiatic 
specimens from the Altai Mtns. (Regel), China, Shensi 
(Giraldi, no. 121), and from Japan, Hondo (Faurie, no. 
345) which I have doubtfully referred to L. heterophylla 
and L.Glehnii, but may belong to L. alpigena; this would 
greatly extend the range of L. alpigena. — Sometimes cul- 
tivated (Arnold Arboretum, etc.). 
A. Leaves glabrous or pubescent beneath. 
B. Corolla glabrous without; bractlets small; leaves glabrous or 
slightly pubescent. 
Typical form. 
f. MACROPHYLLA, Arcangeli, Comp. FI. Ital. 319 (1882). 
Differs in its large, quite glabrous leaves. 
f. nANA, Dippel, Handb. Laubholzk. 1: 243 (1889).— 
Nicholson, Dict. Gard. Suppl. 502 (1901). 
Chamaecerasus alpigena nana, Carriére, Rev. Hort. 1887 : 63 (1887). 
A dwarf form with the leaves beneath and the peduncles 
pubescent. 
BB. Corolla hairy without; bractlets one-third to one-half as long 
as ovaries; leaves dark green above, pubescent beneath. 
f. semiconnaTA, Zabel in Beissner, Schelle & Zabel, Handb. 
Laubholz-Ben. 453 (1903. ) 
L. Webbiana, Dippel, Handb. Laubholzk. 1: 243. f. 755 (1889), not 
Wallich. 
AA. Leaves beneath and petioles sparingly glandular. 
f. GLANDULIFERA, Freyn, Zool.-Bot. Ges. Wien 38 : 609 
(1888).
