sides of the branches/ appearing in succes- 

 sion great part of siiiiimcr. It is a native of 

 Africa. 



There are varieties; with yellow flowers, with 

 sulphur-coloured flowers, with white ilowers, 

 with copper-coloured flowers, having mostly a 

 reddish or brown spot near the base of each 

 petal. 



The tliird rises with a shruhhv stem, dividinc; 

 and branching irregularlv, tiiree or four feet in 

 heitrht: the leaves oval, thick, obtuse, succu- 

 lent, surrounding the branches by fours: the 

 fioweis are sulphur-coloured, on long footstalks 

 from the bides of the branches, appearing most 

 part of summer. It is a native of Africa. 



There is a variety with flanie-yellow-coloured 

 flowers. 



The fourth species has under-shrubby stalks : 

 the leaves close-sitting, with linear acute folioles. 

 It is a native of Africa. 



The fifth has the leaves foot-stalked, and 

 clubbed fleshy lobes. 



Culltire. — The first sort is raised from seeds, 

 ■which should be sown in the spring in pots filled 

 with light sandy mould, or on a hot-bed. When 

 the plants have a few inches growth, they should 

 be removed into separate pots plunging them 

 into a hot-btd, admitting air so as gradually to 

 harden them to the open ground. They should 

 be protected for a winter or two, and then be 



turned out into border^, or other parts, where 

 the situation is warm and the soil dry and 

 rubbishy, as they are of a succu'ent nature. 



The oth'-i sorts are capable of being uicieased 

 by cuttings and seeds; the cuttings should be 

 planted out in the spring or sununerin pots filled 

 with lioht sandy mould, and plunged in a hot- 

 bed, being occasionally «..'cred, when they 

 quickly emit rots, and shoot at top; and when 

 sown in the summer months, they may be 

 planted in a sbadv place, or in pots placed m the 

 shade, giving frequent waterings, when they 

 will also take good rooot. In either method,, 

 they should be potted off separately towards 

 autumn, in order to be moved into the green- 

 house or glass-case in the beginning of autumn.- 



The seed should be sown in the spring in pots 

 of light earth, and be plunged in a hot-bed, 

 where they soon come up: when a little ad- 

 vanced in growth, they shoeld be pricked out in 

 separate small pots, being watered and replunged 

 into the hot-bed till well rooted, when they 

 should be gradually hardened to the full air, and 

 in June set out to remain till the autumn, when 

 they should be placed in the green house, or 

 sonjc other place where they may have protec- 

 tion for the winter. 



The first sort affords variety in the borders, as 

 well as among potted plants ; and the others in 

 collections of the green-house kind..

iiAHLTA. This genus was established by the 



late Cavanillcs, in honour of Dr. Andrew 



Dahl, a Swedish botanist, and the friend of Baron 

 Alstrcenier. 



It belongs to the class and order Syvs^tnesla 

 P(jhjgamia Fnistranea, at least in this cold cli- 

 mate. 



The stems die every winter, but the root is 

 perennial and tuberous, not very dissimilar lo 

 that of the Artichoke. 



Four species have been described. 



1. 1 innnta, pinnated as it is called, and figured 

 by Cavanilles in his Ic. PI. v. 1. tal. SO. It is 

 also fiiiLTed under this name in the -Ith vol. of 

 Andrew s's But. Refioiilori/. In the jinmde^ du 

 Mvs. Kali'. iial Hist. Nat. v. 3. M.Thouiu calls 

 this species Purpurea, but its colour varies from 

 the common Pinuata, being verv deep ; and Mr. 

 H. A. Salisbury suspects that this Purpurea of 

 Thouin is- the true Rosea of Cavanillcs. A 



paler coloured variety of the Pinnnta, the seeds- 

 of which were sent to Holland-House with the 

 name of Rosea bv Cavanillcs, has been lately 

 figured by Mr. Hooker in the Parad'istis Londi- 

 neiisis, and described by the above-mentioned 

 botanist, under the name of Sambiicifolia : that 

 it is not the true Rfi^ea of Cavanillcs, Ic. is un- 

 questionable ; for the leaves v.ere simply pinnate, 

 not bipinnate. 



'J. Riiscu, Rose-coloured. It is so called and 

 figu.red by Cavanilles in liis Ico/ies ; but the plant 

 called Piosea by M. Thouin in the Annates, is 

 most probably the very variety of the first spe- 

 cies figured by the name of Samlncifulia in the 

 Par ad is us Lnndinensis. 



3. Coccinea, Scarlet. This is figured in Ciirtis's 

 publicatii>n ; but we entertaii. a doubt if it is the 

 same with Cavanilles's plant, if the colour is well 

 copied. The plant, we understand, is dead. 



4. Crcc-itii, Saffron -coloured. This plant is
