The Peach and Nectarine Trees distinguished by their germens. Mr. 
John Mitchell, gardener, Slapton, Devonshire, has discovered a method of dis- 
tinguishing Peach and Nectarine trees at an early stage of their growth, when 
both first produce blossoms; to effect this he dissects a few of the flowers of the 
trees about which he is doubtful; and that which produces a villous germen 
always proves a peach tree, whilst those producing germens smooth, and shining, 
always proves a Nectarine tree. Gard. Mag. 
Method of freeing Fruit Trees from Moss and Insects. Mr. James 
Thomas of Derveruden Green, near Chepstow, has found the following mixture 
an excellent application for the purpose. The mixture is made by taking five 
bushels of well-burnt lime, fresh from the kiln, and slaking it with hot water, in 
which salt has been dissolved. When the lime has fallen to a fine dry powder, 
add, by small quantities at a time, a bushel of soot, stirring it in till the two 
ingredients are completely incorporated. Advantage is taken of the first foggy 
day when the trees are damp, but not dripping, to dust them over with this 
powder. One man may treat fifty trees in a day, and the operation, in Mr. 
Thomas's opinion, should be repeated twice a year ; the first time March, and the 
next in October or November. Transactions of the Society of Arts. 
American mode of Planting Potatoes. Dig holes three feet distant, put 
the usual quantity of dung at the bottom of the holes; put in each hole three or 
four sets, and if it should be a dry summer, the roots will have the advantage of 
moisture : while they are growing, frequently mould them up well, as there will 
be suflScient room.

New and very Rare Plants, figured in the Periodicals for September. 
CLASS I.— DICOTYLEDONES, OR EXOGENES. 
CACTE^jE 
Mammill^ria te'nuis. — Taper Mammillaria. This curious and beautiful 
little plant, ought to be obtained by every lover of succulent plants; its flowers 
are small, and of an ocherous-white colour ; its native country is unknown to us. 
Introduced by M. De Candolle. Culture. — It flowers in May, and propagates 
readily by means of the little round hedgehog-like bulbs, which it produces in 
abundance. They should be planted in lime-rubbish, and a little vegetable soil 
kept just damp, where they will strike root, and speedily establish themselves. 
Once rooted, nothing but frost or over-watering will destroy them. — Bot. Reg. 
LEGUMIN^OSjE. 
Ho'vea chorozem.ef^olia. — Chorozema-leaved Hovea. Flowers dark pur- 
ple. Native of New Holland, from whence it has been lately introduced. Cul- 
ture. — It is a very healthy green-house shrub, and will thrive, we suppose, like 
the rest of the species, in equal parts of sandy-loam and peat. Young cuttings 
will strike in sand under a bell-glass. — Bot. Reg.
