Description. — A large skrnl or i;inall tree, witli brown warted bark ; 

 yonvg branches covered with adprosped silky nifous pubescence. Leaves 

 with about twenty pairs of elliptico-obovate leaflets, glabrous above, as 

 well as the channelled cununou petiole slightly liairy below, hairs ad- 

 pressed, rufous. Floirers upon tbo i>lant at the same time as the leaves, 

 in lateral racemes, pedicellod. (^aly.r cylindrical, abruptly, and some- 

 what obliquely truncated at both extremities, toothed, shortly but 

 densely pubescent. Corolla bright yellow ; vexillum about three times 

 as long as the calyx, rotund, sui)cordate at the base, somewhat shorter 

 than the other petals ; alse cultrato-elliptical, cordate at the base, claw 

 linear, bulging outwards ; keel a little longer than the wings, dipeta- 

 lous, petals elliptical, semicorduto on the upper side, spreading and 

 revolute at the lower margin, so as, in the space left between them, to 

 expose the stamens to their base, claws longer than those of the aloe, 

 and straight. Stamens as long as tlie keel ; filaments subulate, glabrous, 

 spreading at their apices ; anthers small. Pistil as long as the stamens ; 

 germen covered with silky adpressed rufous hairs, and marked exter- 

 nally by the numerous ovules ; style subulate, nearly straight, nearly 

 glabrous ; stigma minute. LegurM moniliform, 4-winged, wings ap- 

 proach in pairs above and below. Seeds roundish, yellowish-brown. 



This very handsome plant has been many years in cultivation in the 

 Royal Botanic Garden, Edinburgh, having now a stem of eleven inches 

 in circumference. We do not know when or Avhence it was intro- 

 duced, and I have not observed it in any other collection. I cannot 

 but entertain a fear that it is a seedling variety of Edwardsia grandi- 

 /om, but it is in a moment distinguished from the ordinary form of this 

 by its subequal petals, by the Avide separation of the petals of the 

 keel, and by its flowering Avlien in full leaf. Every year till this one, 

 it had thriven well and flowered profusely upon a south wall, and lived 

 but did not blossom nor thrive as a standard. In last winter, memo- 

 rable for the ruin it effected among much more than half-hardy shrubs, 

 it suffered much less than Edwordsia grandiflora or E. microphylla, -plunts 

 of which, about the same si>ie aud age as E. Macnabiana, and on the 

 same wall with it, were killed to the ground ; but still it was much cut, 

 and it did not flower this year. Mr Macnab feels more confident than 

 I do of its being entitled to rank as a species, and to him, therefore, 

 I have dedicated it. 



Gesneria elongata, var. 



G. elongata, var. fruticosa, pubcscens, ramosa ; foliis oppositis, lanceo- 

 lato-ovatis, acuminatis, longe petiolatis, base insoqualibus, subsequa- 

 liter serratis, supra pubescentibus, subtus moliter tomentosis ; um- 

 bellis axillaribus, 4-floris, folio brevioribus ; corollis villosis, tiibu- 

 losis, fauce parum constvictis. 

 Description. — Whole plant villous. Stem (5 feet high) shrubby, much 

 branched, branches ascending. Leaves (^-G inches long, 1^-2^ broad) 

 opposite and decussating, petiolate, lanceolato-ovate, acuminate, neatly 

 and subequally serrated, somewhat harshly pubescent, and bright green 

 above, white, with soft tomcntum below. Umbels 4-flowered, villous, 

 shorter than the leaves, pedTinch^ shorter than the petiole, pedicels, 

 about two-thirds the length of the peduncles, bracteae 2, opposite, lan- 

 ceolate, at the subdivision of the umbel. Floicers unilateral. Calyx 

 with small spreading ovato-subiilato segments. Corolla {I inch, long, 

 h inch across) tubular, clavato-ventricose, dilated and somewhat fleshy 

 at its base, then contracted, and after being dilated, again slightly con- 

 tracted at its mouth, villous on the outside, glabrous within ; limb 

 spreading, lobes subequal, rounded, crenate. Stamens inserted into 

 the base of the corolla, and rising to the throat ; filaments pubes- 

 cent : anthers divaricated at the base where the connective is dilated
