length of the calyx, throat slightly ventricose, bearded within, sprinkled 

 with numerous mmute darker-coloured spots, lower lip of tliree nearly 

 equal entire lobes, those at the aide retlexed; the upper lip nearly 

 straight, slightly emarginate, edges folded back. Stamem dark lilac, 

 scarcely projecting beyond the upper lip; filaments straight, distant, 

 but not spreading, glabrous, compressed ; anther-lobes diverging, naked. 

 Stigma bipartite, segments acute, the upper rather the shorter. Style 

 filiform and glabrous, rather longer than the stamens. Germen 4-lobed, 

 erect, on a small disk. 

 This species was raised by ISIr Neill from seeds communicated from Chile 

 by the gentleman to whom I have dedicated it, and by whom, in con- 

 junction with Mr Cruckshanks, so new an appearance has within these 

 few years been given to our greenliouses. 



Niei'embergia linariaefolia. 



N. linaricrfoKa; foliis spathulato-linearibus cauleque glanduloso-pubes- 

 centibus ; caule herbaceo, erecto, ramoso. 



Descriptiok. — Root fibrous, annual ? Stem herbaceous, erect, slender, 

 much branched, glanduloso-pubescent. Leaves very numerous, scat- 

 tered, spreading, flat, slightly channelled, spathulato-linear, the upper 

 smaller, and lanceolato-linear, middle rib prominent behind, scarcely 

 veined, glanduloso-pubescent. Flowers solitary, opposite to the leaves, 

 peduncled. Peduncle erect, nearly as long as the leaf, glanduloso-pu- 

 bescent. Calyx 5-cleft, tube lO-ribbed, the alternate ribs going to the 

 apex of the segments, or parted to go along the edges of the contiguous 

 segments; segments lanceolate, concave, spreading. Cwolla hypocrateri- 

 form, glanduloso-pubescent on the outside, glabrous within ; tube (8 lines 

 long) very slender, purplish; limb shghtly concave, of five unequal, irre- 

 gular, broad, short, overlapping, somewliat cordate segments, white, lilac 

 plicate and 3-ribbed in the middle; tliroat yellow. Stamens 5, arising from 

 the throat of the corolla, erect, included, unconnected, but contiguous 

 and closing the throat, unequal, 3 short, 2 long, one of the short ones 

 being placed between these last, and reflected ; filaments slightly pubes- 

 cent on the outside; anthers yellow, bilocular, bursting along their 

 edges ; pollen paler, granules spherical. Pistil single ; germen ovate, 

 seated in a thin cup-shajjed white disk with ragged edges, purple, gla- 

 brous, 4-sided, with four prominent furrowed ridges, 4-valved, bilocu- 

 lar, septum in the very young state double, placenta large, central, at 

 length free ; style slender, dilated flattened and kidney-shaped at the 

 apex, along which the broad green shining linear stigmatic surface is 

 marginal. Ovtiles numerous.

Lobelia rcbusta. 



L. robmta; caule suffruticoso ; foliis obovato-lanceolatis, acuminatis, 

 grosse dentatis, glabris, nitidis ; racemis terininalibus, simplicibus. 



Desciuption Root perennial. Stem very stout, erect, half woody, 



branched, green and glabrous, irregularly winged with the persistent 

 decurrent occasionally wavy bases of the leaves. Leaves numerous, scat- 

 tered, crowded towards the apex, falling olf below, obovato-lanceolate, 

 acuminate, attenuated at the base, and decurrent for a little way along 

 the stem, glabrous, pale green and shining, waved, coarsely and sharply 

 toothed, veined, middle rib and veins prominent behind, and, especially 

 when young, lilac-coloured. Raceme terminal, gradually elongating, sup- 

 ported on a naked, slightly villous stalk. Flotvers large, very numerous, 

 secund, crowded. Pedicels (1 inch long) compressed, finely villous, each 

 with one bractea at the base, and two nearly opposite below the middle. 

 BraclecB linear, acute, villous, entire or sparingly toothed, the lowest 

 nearly as long as the peduncle, and decurrent, the others shorter. Calyx 

 5-parted, green, villous, persistent, segments deltoideo-linear, acuminate, 

 serrated, at length rellected at the apex. Corolla deep and dull purple,
