3. H. angustijblia. De Cand. Prod. b .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 u trin q u e atten u atis 3-5-nerviis subdenticulatis cano-sericeis eglandulosis,
involucro ebracteato hispidulo, acheniis estipitatis obovatis gibbis muticis, re-
ceptaculi pa leorum serie exte riore basi gamophyllo.
We cannot refer this satisfactorily to any of De Candolle’s species ; it may be perhaps his H. luzuloefoliu,
but the stem and leaves can neither he called villous nor hirsute.
5. H. (Olocarpha ) luzulcefolia. De Cand. Prod. b .p . 693.
This we are not acquainted with.
6. H . (Olo carp h a) caule suffruticoso erecto simplici pilis mollibus hirsuto,
foliis intege rrimis linearibus uninerviis piiis 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 exte riore gamophyllo, achenio oblongo basi
a tten u a te .
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. D e 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 ; bracteæ and uppermost leaves terminated by a sessile
brown shining gland ; leaves of the involucre terminated by a large thick cylindrical gland, concave a t the
apex, the margin serrated, the serratures thick, cylindrical, and resembling callous glands. Achenium obovate,
gibbous, without any beak ; receptacle covered with paleæ, which are curiously and inegularly uniied together,
like honeycomb, at the base— De Candolle says of his plant, “ Priori {H. luzulafolia) prima fronte
simillima,” whereas ours bears no resemblance to any other of the genus.

(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 Petersburgh and Breslau, produced
plants with a pappus. The branches of the style of the florets of the disk present also a different appearance.

This genus differs from Oxyura by the achenia of the disk having a pappus and being pubescent; from
Callichroa, by the form of the achenia, the entirely paleaceous receptacle, and the pappus being unequal in
length and rather more paleaceous ; from Hartmannia, by the paleæ of the pappus not being membranous,
and the form of the achenia of the ray ; and from Madaraglossa, by the paleæ of the pappus not plumosely
ciliated or villous at the base. It is unnecessary to propose a new generic character, as that given by Fischer
and Meyer, combined with Schauer’s observations, 1. c., under Oxyura and Callichroa, is sufficient.

Very similar in habit to the two preceding ; our wild specimens were collected by Mr Douglas, although
unnoticed as such by De Candolle.
1. Ha rtm an n ia De I d. Prod. 5. p . 693.
The palete to the florets of the disk are about eight in number (not five as in De Candolle’s generic cliarregularly
inciso-serrated towards the apex ; the
e can scarcely be called obtuse as they are deraeter),
equal in length, but unequal in breadth, aud i
terminal tooth or segment being very acute, so that the \
scribed in De Candolle’s Prodromus.
2. H. corymbosa. De Cand. Prod. b .p . 694.
With this we are unacquainted.
3. H . ciliata. D e Cand. Prod. 5. p . 694.
This aiso we have not seen ; the want of a pappus seems to remove it from the genus ; perhaps it ought
to be united to Oxyura.
4. H .? pungens; berbacea basi sublignosa confertim foliosa, caule p arce ramoso pilis
albidis setoso, foliis inferioribus pinnatifidis, lobis oblongis vel oblongo-lanceolatis spinoso-
mucronatis, superioribus ac fasciculorum axillarium linearibus integris rigidis spinescentibus
margine recurvis papilloso-pilosis, capitulis subsolitariis bracteatis, involucri squamis
spinescentibus glandulosis lígulas radii bifidas subæquantibus, acheniis epapposis radii
gibbis areola terminali valde obliqua, receptáculo toto paleaceo, paleis lanceolato-subulatis
spinescentibus. Hook. Ic. PI. v. 4. t. 334.
This is a very remarkable plant, more like a species of Navarretia among the Polemoniacea than one of
the present Order. We can find no trace of it in De Candolle’s Prodromus.
1. Layia gaillardioides ; decumbens setis patentibus rigidulis undique hispida, foliis
oblongo-lanceolatis inferioribus inciso-serratis superioribus integris, ramulis floribus
monocephalis subelongatis, ligulis 12-15 obovatis apice trifidis discum duplo sup eran tibus,
pappo disci fulvo.—Layia galardioides. De Cand. Prod. 7. p . 2 94.— T rid a x ? Hook,
et A m . supra, p . 148.
The genus Layia, which we had suggested for this plant, is the same as Madaraglossa, the only difference
being that in the latter the paleæ of the receptacle are all placed between the ray and the disk, not spread
over it. The above species we have not received from Douglas. L a y ia we retain to a leguminose plant
described supra, p. 182.
