to improve in point of colour or habit those already esteemed 
hardy : one hardy species, L purpurea^ commonly known as 
Convolvulus major , seems to possess a natural inclination to sport; 
and from this, and its naturally hardy character, it might be 
selected as the female parent of a progeny yet unborn, but pro¬ 
bably possessing the gorgeous colouring of their male parents, 
combined with the robust constitution of the one last named. 
Besides this, there are several others, now nearly obsolete, but 
which might be revived for such a purpose, being both hardy 
and of different, colours to those commonly grown. 
In conclusion, I will mention one other species :— 
I. quamoclit, one of the prettiest little annuals grown. This 
should be sown in heat about the middle of March, and potted 
off when about three inches high ; keep them frequently re¬ 
potted, using a mixture of two-thirds leaf mould, and the other 
part loam, till they are placed in large 32’s; continue them in 
heat till they show flowers,—then they may be removed to the 
greenhouse. These require only a small wire trellis. Some care 
is necessary to avoid over-watering. With this I take leave of 
one of the most splendid groups in British collections.

THE LATE PROFESSOR DON. 
It is our melancholy task to notice the demise of the late Mr. 
David Don, recently Professor of Botany in King’s College, Lon¬ 
don ; in whom botany, both in theory and in practice, has lost one 
of its most zealous, able, and successful students, and society one 
of its most amiable and estimable members. 
As Professor Don was in the strictest sense of the terms a here¬ 
ditary botanist, naturalist, and man of general information, it may 
not be amiss, before giving an exceedingly brief outline of the 
principal events of his life, to say something still more brief of his 
father. We have no occasion to dilate upon the character of either; 
they are safe in the memories of large circles of friends ; and 
wherever either had an opportunity of making an impression, the 
remembrance of it is delightful.
