SYNOPSIS OF THE GENUS LONICERA. 211 
142 x 146. L. dioeca X flava. 
L. flava, Borie, Rev. Hort. IV. 53 221. pl. 72 (1856). 
This hybrid seems to occur sometimes in gardens under 
the name L. flava. 
144 X 145. L. urrsuta X SuLtivanti, Sargent, Gard. & 
For. 9: 344. f. 46 (1896). 
This hybrid originated probably in the botanic garden 
_ at Cambridge, Mass., where it was first noticed by Prof; 
Sargent and it is still in cultivation there. 
144 * 146. L. hirsuta X flava. 
L. Douglasii, K. Koch, Dendr. 2 12 (1872), not De Candolle. 
Caprifolium Douglasii, hort., not Lindley, ex Dippel, Handb. Laub- 
holzk. 1; 210 (1889). 
This form is found in cultivation as L. flava, Douglasii 
and hirsuta (Goettingen, Arnold Arboretum, etc.). Koch 
and Zabel consider it a hybrid of ZL. hirsuta and dioeca, 
but the plants I saw suggested the parentage given above. 
145 x 146. L. SuLiivanti X FLAVA, Zabel in Beissner, 
Schelle & Zabel, Handb. Laubholz-Ben. 450 (1903). 
L, flava, hort., not Sims, ex Zabel, J. c. 
L. Schmitziana, hort., ex Zabel, J. c. 
I have seen no plant which would suggest a cross 
between these two species. 
23. Subsect. Eucarprrro.ia. 
147 & 148. L. implexa X< Caprifolium. 
A specimen which I take to represent this hybrid was 
collected by Tommasini near Trieste (in herb. Berlin!). It 
generally resembles L. implexa, but the leaves are larger 
and thinner, the corolla more deeply two-lipped, only
