3. H. angustifolia. De Cand. Prod. 5. p. 692. 

 We have seen no specimen according with the description given of this. 



4«. H. (Olocarpha) sericea ; caule herbaceo erecto cano-tomentoso apice corymboso, 

 foliis lineari-lanceolatis utrinque attenuatis 3-5-nerviis subdenticulatis cano-sericeis eglan- 

 dulosis, involucro ebracteato hispidulo, acheniis estipitatis obovatis gibbis muticis, re- 

 ceptaculi paleorum serie exteriore basi gamophyllo. 



We cannot refer this satisfactorily to any of De Candolle's species ; it may be perhaps his H. luzulcefolia, 

 but the stem and leaves can neither be called villous nor hirsute. 



5. H. (Olocarpha) luzulcefolia. De Cand. Prod. 5. p. 693. 

 This we are not acquainted with. 



6. H. (Olocarpha) Jilipes ; caule suffruticoso erecto simplici pilis mollibus hirsuto, 

 foliis integerrimis linearibus uninerviis pilis mollibus hirsutulis eglandulosis, inferioribus 

 elongatis acuminatis in axillo fasciculos foventibus, superioribus multo minoribus 

 bracteiformibus nigro-glandulosis, corymbo laxo, ramis glabris filiformibus rigidulis, 

 capitulis solitariis longe pedicellatis paucifloris, involucro obconico hirsuto ebracteato 

 oligophyllo, receptaculis palearum serie exteriore gamophyllo, achenio oblongo basi 

 attenuato. ' 



The corymb is lax, the primary branches bear a few glanduliferous bracteas or leaves, but the stalk that 

 supports the capitulum is slender, quite naked, and rigid. In habit it is very dissimilar to the other species. 



7. H. (Olocarpha) macradenia. De Cand. Prod. 5. p. 693. 



To this we presume a specimen we have from Mr Douglas belongs, but it differs considerably from the 

 definition given by De Candolle. In that before us the stem seems to have been decidedly shrubby, branched 

 only towards the extremity, the branches simple, or sometimes bearing again a couple of branches at the apex ; 

 these, as well as the foliage, are slightly hairy ; leaves linear, lower ones about an inch and a half long, and 

 decreasing upwards to scarcely half an inch ; about half a line broad, quite entire, often bearing fascicles of 

 young leaves in their axils. Capitula sessile, solitary, terminal, or on very short leafy axillary opposite 

 nearly terminal branchlets ; involucre bracteated ; bractese and uppermost leaves terminated by a sessile 

 brown shining gland ; leaves of the involucre terminated by a large thick cylindrical gland, concave at the 

 apex, the margin serrated, the serratures thick, cylindrical, and resembling callous glands. Achenium obovate, 

 gibbous, without any beak ; receptacle covered with paleag, which are curiously and irregularly united toge- 

 ther, like honeycomb, at the base De Candolle says of his plant, " Priori ( H. luzultzfolice) prima fronte 



simillima," whereas ours bears no resemblance to any other of the genus. 



1. Oxyura chrysanthemoides. De Cand. Prod. 5. p. 693. Lindl. in Bot. Reg. fol. 1850 

 (quoad descriptionem). 



De Candolle's description agrees well with our wild specimens from Douglas, but not with the figure in the 

 Bot. Register, which, however, appears to be the plant generally, if not solely, cultivated under this name. 

 Lindley, indeed, says, that the pappus there represented to the florets of the disk, was introduced by an 

 inadvertency of the draughtsman ; but seeds sent to the gardens of St Petersbusgh and Breslau, produced 

 plants with a pappus. The branches of the style of the florets of the disk present also a different appearance.
