these infallible directions are in their turn followed and aban¬ 
doned as delusive by those who are really anxious to secure a 
display, and they fall at last to the opinion that to be good the 
seed must be imported. Now let us look at the rationale of the 
subject: double stocks are a consequence of some uncommon 
condition in the parent which bore the seed, and every circum¬ 
stance goes to prove that condition to have been an extremely 
vigorous one, for no one ever obtained good flowers from small 
inferior seed. Let the question be fairly tested by experiment: 
plant the single stocks in rich ground as early as may be pru¬ 
dent, so as to have them strong before they commence blooming ; 
trim off all the lateral shoots, so as to throw the whole vigour of 
the plant into the central stem, and, to further improve the 
quality of the first-formed seed, remove the point of the main 
stem, and after properly ripening the remainder, sow it again 
upon light rich earth, and if the produce is not nearly nine tenths 
double, I shall be gravely deceived; this is the practice with the 
Dutch florists, and indeed all who raise thoroughly good seed, and 
hence the superiority of that which we import. It does not 
matter whether the sort be the little ten-week, the larger inter¬ 
mediate, or even the giant itself; they are operated on by the 
same cause, which is so simple as to come within the compre¬ 
hension and means of all, and may be fully proved in a couple of 
seasons. J. T. N.

GesneriacetE, —Didynamia Angiospermia. 
Alloplectus concolor (Hooker). An undoubted congener with 
Alloplectus diochrous, having the same habit, but smaller flowers; 
calyx and corolla uniformly red, the latter much more ventricose 
above, at the upper part of the tube, with the mouth more ob¬ 
lique. It is, we presume, an inhabitant of Brazil, having been 
sent to Kew by Mr. Galeotti, in 1848, under the garden name of 
A. eriocalyx , without any indication of its locality.— Bot. Mag.

introduced by Messrs. Veitch, of Exeter, through their indefa-
