I have added “fertile” or “ barren ’’ according to my own experience. . 
I have found many hybrids fertile, but none constant from seed. I have 
never been able to obtain anywhere or to get authentic information of a 
true hybrid constant from seed. Many hybrids come of which it is hardly 
possible to say which is the seed parent, or what the hybrid is between. 
This is especially the case in Aquilegia and Dianthus. I may remark 
that in my garden, seed of Dianthus cesius, saved from collected wild 
specimens, at once departs from the type, generally in the direction of 
the garden Pink, commonly called D. plumarius, but I suspect that D. 
cesius is an important factor in garden Pinks. It passes in about three. 
or four generations into a double garden Pink ; it may of course be ferti- 
lised in every generation by the pollen of the garden Pink, said to be 
D. plumarius. The seed parent—and in most cases I have certain means- 
of knowing—is the first on the labels of the specimens sent. 
POLEMONIUM 
Polemonium hybridises very freely; hybrids mostly barren, P. cwrv- 
leum x P. reptans seems to be an exception. 
P. flavum x P. ceruleum.—These frequently come from seed of P.. 
flavum. They may be at once recognised by feeling the heads after 
flowering. The hybrid has an empty calyx; the species P. corulewm 
swells the seed pod directly. 
P. ceruleum (var.) x P. humile. 
ORCHIS 
Orchis foliosa x O. maculata.—These come up by the side of clumps 
of O. foliosa, but like some other plants ail the spontaneous seedlings are. 
hybrid, and none ever comes typical. 
HEUCHERA 
Heuchera sanguinea x H. cylindrica (fertile). 
ie = x H. hispida (fertile). I have raised seedlings. 
from both these hybrids ; they come gorgeous nondescripts. 
CAMPANULA 
Campanula rhomboidalis x C.rotundifolia.—I cannot be certain 
which is the seed parent, but where they grow together intermediate forms. 
in every degree are endless. Many of them produce abnormal corollas ; 
but these abnormal forms are not confined to hybrids.

LILIUM 
Liliwvm Martagon, var, dalmaticum x L. Hansoni (fertile).—'These have: 
come in several parts of my garden from seed collected from L. Martagon 
in a frame, and sown broadcast, I send also a curious effect of a cross 
between L. Martagon, var. dalmaticum, and L. Martagon type, showing 
mired flowers. 
VERBASCUM 
Verbascum phaniceum x V. nigrum.—Barren in my experience, but 
My. Lynch has sent me from Cambridge seed of V. cuprewmn, which is a
