 very shortly deltoid ; corolla-tube far exserted, deciduous, quite 

 naked inside, widened towards the throat ; the lower lip gibbous 

 at the base ; stamens 4, didynamous, the two sterile ones a little

HuiLLA. — An erect shrub or a perennial frutescent herb, 2 to 4 ft. 

 high or more, woody at least at the base, throughout sweetly scented like 

 Ochnum hasilicum but not strongly so, sparingly branched at the apex ; 

 main stems nodose, cylindrical, pale greenish, somewhat fleshy ; 

 branches mostly opposite ; leaves opposite, often with fascicles of 

 other leaves in their axils, somewhat fleshy-coriaceous, rather rigid, 

 erect, pale green and densely but not pellucidly punctate on both faces, 

 denticulate towards the apex, pleasantly aromatic ; midrib prominent 

 above, channelled-impressed beneath ; flowers arranged in dense 

 compound axillary shortly pedunculate spikes, forming long terminal 

 cylindrical glandular racemes ; calyx bibracteolate at the base ; the 

 tube shortly tubular-campanulate, truncate at the mouth, deeply 

 5-crenate, minutely glandular outside ; corolla coloured as in Salvia 

 pratensis L. ; the tube much longer than the calyx, curved in the 

 middle, widened towards the throat ; the limb bilabiate ; the upper lip 

 erect, 3-lobed, the middle lobe sub-emarginate ; the lower lip directed 

 forwards boat-shaped, subentire ; stamens 4, didynamous, ascending, 

 inserted on the corolla-tube, subexserted on account of the gaping of 

 the corolla-lips but rather shorter than they, naked ; anthers versatile, 

 the cells at length confluent and while dehiscing peltate-circular ; 

 style filiform, but little curved, terminating in the small subtruncate 

 more deeply coloured stigma ; young nutlets obtusely ellipsoidal, 

 somewhat compressed, angular, smooth, whitish ; bracteoles violet- 

 purple, much exceeding the calyx, marked near the apex outside with 

 a large circular gland which is tumid at the margin. In wooded rather 

 elevated damp thickets in Morro de Lopollo, in company with Mela- 

 stomaceas and species of Xyris, between Catumba and Hai ; fl. beginning 

 of April 1860. No. 5615. A shrub, 3 to 4 ft. high, erect, sparingly 

 branched ; bracts, etc., violet-purple. In thickets at the outskirts of 

 the forest between Eme and Ivantala, 'rather rare ; fl. and fr. end of 

 May 1860. No. 5616. 



Plectranthus Welwitschii Vatke, mentioned by Briquet, I.e., under 

 uE. ohtusifolius Briq., included ^E. Engleri. yE. obtusifolius is stated 

 to have been collected by Welwitsch, no. 473, at Malandsche (Malange) ; 

 this is an error ; probably Mechow was the collector intended to be 

 mentioned. I have not seen the type of yE. ohtusifolius, but from 

 Briquet's description I suspect that Vatke was right in considering it 

 as conspecific with yE. Engleri. Briquet, I.e., p. 190, describes also 

 from Angola jE. fiorihundus, the type of which I have not seen ; but 

 he states that it is very near to ^E. ohtusifolius, and that the two should, 

 perhaps, be considered as forming varieties of an aggregate species for 

 which he suggests the former name. The three species, namely, these
