This is a very handsome plant, with large purple flowers, which sometimes 

 measure 2 in. across, and are quite white in the centre. It was found by Mr. 

 Gardner on the Organ Mountains, in rather boggy soil, at about 3000 ft. 

 above the level of the sea. (^Bot. Mag., April, 1843.)

A handsome greenhouse or stove shrub, with clusters of rose-coloured 

 flowers, with blue anthers. The leaves are reddish when young, though they 

 become afterwards of a pale green. The plant should be grown in a mix- 

 ture of turf and heath mould, and watered fi'eely during the summer months.

Avery pretty little greenhouse shrub, which seldom grows more than a foot 

 high, but has such a number of branches that it appears a perfect mass of 

 flowers. The flowers are small, but they are very pretty ; as they are white, 

 tinged with pink. " It is a soft-wooded species, growing a foot high in a sandy 

 peat, and striking readily from cuttings." It is frequently called in the nur- 

 series Doncklaeria diversifolia. {Bot. Beg., April, 1843 ; and Paxt. Mag. of 

 Bot., June, 1843.)

This pretty little plant belongs to a genus very little known in England, 

 though it is met with occasionally on the Continent. The species are all 

 natives of tropical America, where they are found in the mountainous dis- 

 tricts, in sandy places ; and where they have almost the habit of heaths. 

 This plant, which is probably the only one of the genus in Great Britain, 

 flowered in the splendid collection of the Duke of Northumberland at Syon.

This very pretty little plant has flowers so much like those of a peach, 

 except in being smaller, that it is often mistaken for a small almond or peach 

 tree in New Holland ; particularly as rose-coloured flowers are so very rare 

 among the myrtles. This plant flowered in the greenhouse of Messrs. Lu- 

 combe and Pince of Exeter. It requires to have the pots in which it is 

 grown well drained. The leaves, when bruised, smell like lemon. {Bot. 

 Beg., Feb. 1843.)

This very singular passion-flower is named in consequence of its resem- 

 blance to those marine animals, so common on rocky coasts, which are known 

 by the name of the sea-anemone, or actinia. Its flowers are very fragrant. 

 This species is a native of the Organ Mountains of Brazil ; and it requires 

 the usual culture of stove plants. {Bot. Beg., April, 1843.)

This very splendid annual is a hybrid between L. lateritia and L. pent- 

 landica. It is a very handsome greenhouse climber, and will flower freely in 

 the open air during the summer and autumn. {Paxt. Mag. of Bot., 1843.)
