1. Oxalis crenala, notched-petalled Wood-Sorrell. Decandria, Pentagynia. 

 Oxalidece. This variety is a far more robust plant than any other of the 

 genus; it is not on account of its flowers or herbage that it becomes an object 

 of peculiar interest, but from its tuberous roots, which bear a great resem- 

 blance to those of the Potatoe, their form and colour being precisely similar 

 to it. A native of Lima; introduced in 1829; grows to the height of three 

 feet; perennial; flowers in July and September; colour yellow. In regard to 

 the culture of this newly-introduced vegetable, very little knowledge has yet 

 been acquired; but it will grow well iu the open border, providing the soil is 

 rich. Oxalis, from the Greek Oxys, signifying sour, taste of the leaves; 

 Crenata, from the Latin, notched, in allusion to its flowers.— {See Flo. Cab. 

 Vol. I. plate i, and page 45.) 



2. Erica cinerea, grey Heath. Octandria, Monogynia. Ericea?. This 

 hardy British Heath is highly ornamental in the garden, and deserves general 

 cultivation. There are several varieties, as deep crimson, pure white, and in- 

 termediate tints. It grows one foot high ; flowers in July and September; 

 native of Britain. Erica, from Ereico, to break, referring to the fragility of 

 the branches ; and cinerea, signifying ash coloured. 



3. Alstrcemeria pelegrina, spotted flowered. Hexandria, Monogynia. Ama- 

 ryllideae. This plant has usually been treated as a greenhouse plant; it is, 

 however, half hardy, requiring only the cold frame. If it be treated as a 

 border plant, the situation should be warm and dry, and the soil made very 

 light with leaf mould, sand, and the sifted mortar rubbish of an old building. 

 Flowers rosy white, spotted with black; the stems grow one foot high ; blooms 

 from June to September, and is a perennial plant. Alstrasmeria, named by 

 Linnaeus, in honour of Baron Alstrasmaer, who sent him seeds from Spain. 

 Pelegrina is its common name in Peru, which signifies a superb flower. 



4. Aconitum versicolor, Shaded Monk's Hood. Polyandria, Trigynia. Ra- 

 nunculacea. This species is of upright growth, and its flowers are ornamental, 

 it grows three feet high, flowers iu July and August ; is a perennial border 

 plant. The flowers are blue aud white. All the species of Aconitum's are 

 poisonous. Aconitum, from the Greek aeon, signifying a dart, because its 

 poison was used upon darts, to render them the more deadly. 



Soot destroys or drives off from pink beds those common and voracious 

 grubs of gardens, the larva; of the moths of the family Noctuadoe. — Last 

 summer I was troubled with the grub in a bed of pinks : [ then made some soot 

 water, and with it watered the bed well, and the bed was soon freed from the 

 grubs. The precise mode of the soot's action on the grubs I cannot state; but 

 I believe that the ammoniacal matter which it contains destroys some, and 

 disperses the remainder. I shall gladly receive any information on this head. 

 I have not found the soot injure the soil at all ; and [ name this because I had 

 been told it would. — W. Denver, Gard. Mag.
