Evolvulus purpuro-ceerulem ; appresso-pilosus subincanus interne fruticosus e 

 basi ramosus, ramis primariis elongatis erectis secundariis patentibus graci- 

 libus rigidis, fobis patentibus v. recurvis lanceolatis acutis parvis, pedicellis 

 unifloris terminalibus vel lateralibus basi bracteatis, calycis laciuiis parvis 

 lanceolatis patentibus, corollis extus sericeis margine crenulatis. 



A small, but most lovely little suffruticose plant, with copious 

 flowers, at first sight not much unlike those of Anagallis carulea, 

 but borne upon erect twiggy branches with small patent or re- 

 flexed leaves, and worthy a place in every garden on account of 

 the brilliant colour of its blossoms. Its nearest affinity, as to 

 species, and it is certainly an undescribed one, is with Evolvulus 

 Arbuscula of Poiret, according to the Bahama specimens in our 

 Herbarium, thus named by M. Choisy, the author of the " Con- 

 volvulacege" in De Candolle's Prodromus; but that has still 

 smaller and erect leaves, not tapering at the base, like those of 

 the one now before us. — It inhabits arid rocks near the sea, in 

 the district of Manchester, Jamaica ; and caught the attention of 

 Mr. Purdie, its discoverer, and who sent home seeds of it to the 

 Royal Gardens of Kew, by its showy bright blue flowers. 



Our figure was named from a charming specimen, belonging 

 to His Grace the Duke of Northumberland, Syon House. A va- 

 riety has bloomed at Kew, from the same country, with pale blue 

 flowers. It was reared in the stove, and requires to be kept mo- 

 derately moist. Flowers in July and August. 



Descr. Boot perennial, not very stout, throwing out branches 

 and fibres. Stem a foot and a half high, quite woody below and 

 often for more than halfway up, branched from the very base , 

 main branches erect, stout below, gradually tapering upwards and
