DEscniPTioN Stem scarcely woody, very brittle, slender, much branched 



and diffused ; branches green, sp'rinkled with oblong purple spots, pu- 

 bescent, hairs spreading. Leaves (nearly 2 inches long, 1 inch broad) 

 petioled, opposite or ternate, ovato-oblong, doubly and unequally incise- 

 serrated, pubescent on both sides, as well as the branches subviscid, shin- 

 ing and bright green above, paler below, veined and wrinkled, veins pro- 

 minent below, channelled above. Peduncles axillary, umbellate, forming 

 an oblong panicle at the extremity of the branches, the lower peduncles 

 generally sujtporting four pedicels", two of which are occasionally branch- 

 ed, the upper peduncles with fewer pedicels, or simple ; two bractem of 

 the structure and form of small leaves, but more entire, at the origin of 

 the pedicels ; these, as well as the peduncles, pedicels, and calyx, pubes- 

 cent and subviscid ; the whole scarcely exceeding the length of the leaf 

 in the axil of which they are placed. 'Calyjc 4.parled, segments unequal, 

 lanceolate, the upjier the broadest. Corolla yellow, upper lip awanting, 

 there being only a ring, scarcely prominent, passing round the germen ; 

 lower lip extremely slender, and somewhat pubescent at its origin, tur- 

 gid below, and clo'sed by a prolongation of its upper edge, turned up, 

 and brought into contact with the stigma. Stamens two, having their 

 origin from the lower half of the ring which forms the faux of the co-. 

 rolla; filaments erect; anthers large, yellow, and, as in the other species, 

 bilocular, with the lobes greatly diverging, and bursting along the front. 

 Pistil rather longer than the s'tamens ; stigma minute ; style somewhat 

 hooked downwards ; germen pubescent, and, as in other species, conical 

 and furrowed on two sides. 

 The only ])lant of this species which we possess, we received from the Bo- 

 tanic Garden, Glasgow, where it was raised from seed communicated 

 from Lima by Mr Cruckshanks. Its habit and appearance is very dis- 

 tinct from any of the species already in cultivation, and corresponds 

 with a native specimen which I possess through the kindness of Mr 

 Cruckshanks and with the figure of Ruiz and Pavon, sufficiently to in- 

 duce me to consider it as illustrative of the form to which these authors 

 gave the specific name which I have adopted ; but continued experience 

 of the tendency to the formation of mules in this genus, makes me more 

 and more sceptical about the title which very appreciable varieties of 

 form In it have to be considered specifically distinct. 1 noticed in a for- 

 mer Number of the Philosophical Journal some mules which had been 

 produced bv Mr IMorrison, gardener at Granton, near Edinburgh, by 

 artificially impregnating some of the most distinguishable forms of Cat. 

 ceolaria ; 'since then, the same cultivator and others have produced all 

 sorts of mixtures, and shaded species into each other through an infinity 

 of gradations. 

 In the figure of Ruiz and Pavon, the lip of the corolla is much less turgid 

 than it is either in the cultivated or in my native specimen ; but the fi- 

 gures are not always correct in these details, and the station given by 

 Ruiz and Pavon for C. angustiflora, Canta, is the same as that in which 

 my native specimen was picked by Mr Cruckshank. 

 It is with great regret thai I am forced to differ from my excellent and 

 accurate friend Dr Hooker, regarding the species to which this plant be- 

 longs, being fully aware of the risk of error which attends every dissent 

 from such authority ; but the differences between this plant and C. ver-
