rolla wheel-shaped, and of a cobalt blue colour. The species is admirably 

 adapted for a rockwork, and appears to thrive best in a mixture of peat and 

 loam. It is readily increased by division [?]. As the plants of this species 

 are apt to be injured by too much wet, some of them should be kept in a 

 frame during winter. Plants of it have been raised in the Bishop of Roches- 

 ter's garden, at Bromley. The figure has been derived from a plant com- 

 municated by Mr. Mallison, at Sir S. Scott's at Sundridge Park. {The Brit.

 " It is easily known from D. linanselblius and its allies by its hoary leaves and soft flower-heads, 

 which have the leaflets reflexed at the points in a squarrose manner, and covered with minute 

 semitransparent glands." 



D. incanus is a handsome, half-shrubby species, discovered in California 

 by Mr. Douglas, by whom seeds of it were sent to the Horticultural So- 

 ciety, in 1832. Its heads of flowers have their rays of a rich lilac, and 

 their disc of a bright yellow. It grows freely in summer, in any hot exposed 

 situation. During winter it should be protected in a frame. (Bot. Meg., 

 August.)

 t. 1691. Synonyme, besides the synonymes quoted in Gard. Mag. IX. 705., Ipomopsis p'.cta of 

 the French gardens. 



Gilifl coronopifolia Pers., though delicate, is tolerably easy to cultivate, 

 and produces its seeds in some abundance, while the closely related G. aggre- 

 gata D. Bon (see X. 70., G. pulchella of others), which much resembles it, is 

 so impatient of cultivation, that it is already nearly lost from our gardens. 

 Both species are equally handsome. (Bot. Reg., August.) 



CCV1I. Primuldcece. Lubinfa atropurpiirea. Mr. Maund has figured this 

 plant in his Botanic Garden for August, fig. 461., and there given some ac- 

 count of it. We quote as follows : — "On examining the deep crimson petals 

 of the Lubima under a magnifier, we observed a number of minute pearl-like 

 substances, spread over their whole interior surface. Its crimson filaments 

 were also similarly gemmed. They appeared as grains of farina, fallen from 

 the anthers ; but a comparison showed them to be evidently brighter. This 

 induced the application of a more powerful magnifier. The result was gra- 

 tifying. The inner surface of the rich coloured petals, and the filaments also, 

 were now seen to be adorned with prominent glands, each a little globe on 

 a cylindrical pedestal. On the sun's rays being fully reflected on a small por- 

 tion of a petal, it instantly became a most dazzling object ; a groundwork of 

 fine crimson studded with brilliants. The most apathetic may exclaim, 

 Wherefore this labour? wherefore this great splendour and beauty? That 

 these glandular appendages have certain uses in the economy of the plant, 

 none dare deny; but what they are, all are equally ignorant."

 Rhodochiton volubilis Gard. Mag. X. 346. 411. 



This is the Rhodochiton volubilis, of which mention is made in p. 346. and 

 411. " It is clearly," says Mr. D. Don, " a legitimate species of Lopho- 

 spermum." A climbing suffrutescent plant, with stems slender and branched, 

 the younger branches dark purple. Leaves stalked, heart-shaped, acuminate; 

 apparently not so large as those of L. erubescens. Flowers axillary, one from 

 an axil, pendulous. Peduncles slender, from 3 in. to 5 in. long. Calyx large, 

 bell-shaped, widely spreading, membranous, pale purple. Corolla funnel- 

 shaped, of an intense purple, li in. long, clothed with white glandular hairs. 

 This very beautiful climbing plant is a native of Mexico, and was introduced
