*'Very nearly violets; but differ in having a calyx whose 

 dimensions are extremely unequal; three being large, and 

 heart-shaped at the base, but not decurrent, the other two 

 being small, and enclosed within the others. This species 

 forms a small shrub in the mountainous places and woods of 

 Brazil. The flowers are small and scattered; the branches 

 erect, with oblong or obovate leaves. It was introduced by 

 Messrs. Loddiges, in whose collection it flowered. [Bot. 

 Reg., July.) 



Convolvuldcea. 



IPOM^'A 



batatoidea Benth. The male Jalap. A green-house twiner, growing eeveralfbet high; 

 with rich deep crimson flowers; appearing in spring; a native of Mexico; propagated 

 by cuttings; grown in loam, peat, and leaf mould, with a little sand. Bot. Reg., 1841. 36. 



Within a few years, several very showy ipomaeas have been 

 introduced. The I. Horsfallia was considered remarkably 

 splendid, but it is now to be eclipsed by others, particularly 

 the present subject, which is said to be so beautiful "that a 

 rival to it can hardly be found in this most lovely race." 

 The stems do not ramble so much as other species, nor are 

 the leaves so abundant as to overshadow and conceal the 

 flowers; the latter stand forward from the foliage, and fully 

 expand in the early part of the day: at this time, their bril- 

 liancy is beyond representation. It is easily managed. The 

 roots are tuberous, and should be kept warm and dry in winter: 

 as soon as they begins to start they should be watered cautious- 

 ly, but freely afterwards. Leaf mould, peat, and loam, with 

 a little sand, suit it, and it would probably, in our climate, 

 flourish well and bloom beautifully if turned out in the sum- 

 mer in a warm border. This is one of the species which 

 supply the jalap gatherers of Mexico, and was sent to the 

 London Horticultural Society by M. Hartwig. {Bot. Reg., 

 July.) 



CONVO'LVULUS 

 BcopArius Hort. Kev. Canary Rose-wood. A green-house shrub; growing three feet 

 high, with white flowers; appearing in September and October; a native of the Can- 

 ary Isles; propagated by seeds. Bot. Beg., 1841.43. 



Quite unlike a convolvulus: the plate represents the branch- 

 es clothed with axillary cymes of small white flowers. There 

 does indeed appear to be some doubt about its being a con- 

 volvulus, but Dr. Lindley leaves it there for various reasons, 

 one of which is that he cannot make up his mind where it can 

 be surely stationed.
