=A. zamorensis= (Zamora).* _fl._ yellow; sepals orange-red. _h._ 1ft. Columbia, 1875.
=ALLOSORUS.= _See_ =Cryptogramme= and =Pellæa=.
=ALLOTMENT GARDENS.= A system of assigning small portions of land to be cultivated by labourers after their ordinary day's work.
The following are the most important rules to be carried out; but, should occasion arise, other rules must be made to meet particular cases:--
1. Each Allotment should consist of a rood of land (=1/4 acre) to be let yearly at a rent of not more than 10s.
2. The Allotment to be let for one year only, to be re-let to the same occupier, provided his character has been satisfactory during the preceding year.
3. The rent shall be considered due at Michaelmas. If it remains unpaid for one month after that date, the Allotment shall be forfeited.
4. The Allotment to be cultivated solely by spade husbandry, and the same crop shall not be planted on the same part two years in succession.
5. Separate Allotments shall be divided by a space not less than 18in.
6. Any occupier trespassing on his neighbour's Allotment, or in any way interfering or damaging the same, shall not be allowed to hold his Allotment after the expiration of the year.
=ALMEIDEA= (in honour of J. R. P. de Almeida, a Brazilian, who was of great assistance to St. Hilaire while travelling in Brazil). ORD. _Rutaceæ_. Stove trees or shrubs with alternate, simple, entire, stalked leaves. Racemes terminal, divided at the apex into compound thyrse-like panicles. The undermentioned species will grow freely in a mixture of loam, sand, and peat. Partly ripened cuttings will root in sand under a hand glass, in heat.
=A. rubra= (red). _fl._ pink; petals very blunt; racemes compound. September. _l._ lanceolate, acute at base. _h._ 12ft. Brazil, 1849. Evergreen shrub.
=ALMOND-LEAVED WILLOW.= _See_ =Salix triandra=.
=ALNUS= (from _al_, near, and _lan_, the bank of a river; general habitat of the genus). The Alder Tree. ORD. _Betulaceæ_. A genus of deciduous trees and shrubs. Flowers monÅcious; barren ones in long drooping autumnal catkins, lasting through the winter; fertile ones, produced in spring, in oval catkins, resembling a fir-cone in shape, the fleshy scales of which become indurated and ligneous as they approach maturity. Leaves stalked, roundish, blunt. Propagated usually by seeds, which are gathered towards the end of October; they require to be well dried, in order that the cones do not become mouldy. The seeds are sprinkled lightly on the ground with the slightest possible covering. Towards the end of the year, the seedlings will be about 10in. high. They are then planted in rows 1-1/2ft. apart, and 6in. from each other, where they may remain for two years, after which they can be placed out in the situations where they are intended to stand. Planting is best done in November or March; and, if it is designed to make a plantation of Alder, the young trees should be put in holes, made with an ordinary garden spade, about 9in. deep, and about 4ft. apart. They are also increased, but rarely, by cuttings, by suckers, and by grafting.
