 American genus with a very different habit and corolla. 



2. G. ilicifolium^ Z Mnell, Herb. A glabrous shrub of 10 to 15 ft. 

 {Nerust). Leaves very shortly petiolate, broadly ovate, obtuse or acute, 

 bordered by irregular mucronate or prickly teeth, 3 to 4 in. long, coriaceous, 

 much veined but very shining. Flowers of a rich red, in short dense clusters 

 or racemes, axillaiy in our specimens. Pedicels short, with very small bracts 

 and bracteoles at the base. Calvx-seo^ments 3 to 4 lines \o\\^. Corolla-tube

 G, Earlii, the lips \ in. long, the upper one concave and incurved, the lower 

 one divided to the base into 3 equal narrow lobes. Stamens as in G. EarliL 

 Capsule above 1 in. long. 



Queensland. Mount Blackwood, IMackay district, NernsL P. Mueller, Pragm. vi. 87, 

 refers this as a variety to G. EarliL Tt appears to me much nearer to O.pidum, of which 

 It has the narrow-lobed corollas, and only differs, as far as I can ascertain, in foliage. 



9. DICLIPTERA, Juss. 



(Brochosiphon, Fees.) 



Calyx deeply divided into 5 lobes or segments. Corolla-tube usually 

 slender, dilated at the throat, the upper lip concave entire or notched, the 

 lower broader nearly entire or 3-lobed, the middle lobe much broader than 

 the others. Stamens 2, ascending under the iipper lip ; anthers 3-celled, 

 the cells placed usually one higher than the other, but without any basal 

 appendage. Ovules 2 in each cell. Capsule usually Hat, shortly contracted 

 and seedless at the base, the dissepiment separating from 'the valves when 

 opened and turning upwards elastically with the retinacula. Seeds flat.— 

 Herbs. Plowers 1 to 3 together, sessile within a flattened involucre of 3 

 bracts concealing the calyx, the involucres usually several in clusters or short 

 cynics, m the axils of the floral leaves or forming terminal loose spikes or 

 racemes, with usually 2 subulate or spiucscent bracts outside the flat ones. 

 Corolla owing to the peculiar inflorescence, appearing frequently resupinate 

 with relation to the main axis, the upper entire or 2-notched lip becoming

 lanceolate or almost linear, mostly acute, contracted into a very short petiole,
