EPILOBIUM DURIAI J. GAY, A NEW(?) ENGLISH PLANT. 227 
Kew (but considered by him, Monogr. Epilobium, p. 77, identical 
ith the Linnean EZ. montanum), is (I should say) commoner in 
(1..€., montanum L.), authenticated by Haussknecht, and J. 
original £. Durivi (i.e. Durieu n. 348). But let us get on to 
erent main groups. — 
‘‘a. Turtonirerm: turiones ab initio hypogei, brevi postea 
.—E. MonTanum. 
B. SOBOLIFERS : soboles hypogewi internodiis elongatis. — E. 
Durrzr.” 
[ cannot sort my specimens by this diagnosis; I cannot tell 
whether the turions are ‘‘lusu soboliformes” or true ‘“soboles.” 
As to the length of the internodes, it depends on age—even the 
typical green turions (rosettes) grow out at last. In the typical EF. 
Duriei (Durieu n. 343) one specimen has the internodes of the 
stolons elongate, the other specimen not. All my material similarly 
which has linear soboles, with internodes ¢ in. long in ust. 
ussknecht has felt this, and on the next page (p. 36) he gives 
an additional ‘disposition for the determination of the Kuropean 
Epilobiums.” In this we have— 
a. Semina oblonga apice m. m, attenuata pellucilo avpendiculata. 
KE. Dura: J. Gay. Hausskn. Epilob. t. 1, fig. 26. 
b. Semina obovoidea apice rotundata. 
KE. wontanum L. Hausskn. Epilob. t. 1, fig. 19.

closely agreeing with Hausskn. t. 2, fig. 26. In other words, I do 
not believe that a species of E;pilobium can stand firm on such small 
differences in the seed. have examined a great many Epilobi 
Ww. ° » as aS my examination goes, I 
cannot distinguish 2. Duriei from E. montanum by the seed. As
