2. H. corymbosa: annual, hirsute-pubescent; heads nearly solitary at the
summit of the stem or branches; leaves pinnately parted, tapering into a
petiole ; the lobes 5-9 pairs, linear, entire ; rays 15—20, oblong ; ray-achenia
obscurely 4-angular, somewhat rugose or muricate on the back; pappus of
the disk-flowers of 6-8 hyaline irregularly laciniate very acute scales,
about one-fourth the length of the tube of the corolla.—Hartmannia corymbosa,
DC.!prodr. 5. p. 694.
California, Douglas !—Nearly a foot high, slender. Chaff scarious ; the
exterior series united nearly to the acute herbaceous and hairy tips. Achenia
stipitate, tipped with a protuberant areola from the inner margin of the apex.
Pappus wanting in the exterior disk-flowers, according to De Candolle.
3. H. ? ciliata : annual, stem somewhat glabrous, loosely branched at the
summit, but scarcely corymbose; leaves pinnately parted, with the entire
lobes in 5-8 pairs; the lower attenuate into a petiole; the upper (partly
clasping) and the floral ones ciliate; heads many-flowered; rays ample,
10-12, obovate ; achenia all smooth and destitute of pappus. D C.—Hartmannia
ciliata, DC. prodr. 5. p. 694.
California, Douglas.—Plant with entirely the habit of the preceding ; but
the achenia all destitute of pappus and terminated by an areola, and the tube
of the corolla obcompressed ; therefore approaching the following tribe. Head
nearly that of Chrysanthemum Myconis. DC.—This ambiguous plant is
unknown to us.
§ 3. Heads many-flowered, solitary or crowded at the summit of the branches:
chaff of the receptacle in a single series between the ray and disk-flowers,
not united: pappus none : leaves undivided.
4. H. angustifolia (DC.) : stem much branched, suffruteseent at the base ;
the branches, leaves, and involucre minutely pubescent; leaves and bracts
narrowly linear, entire; heads bracteate, somewhat solitary; chaff of the
receptacle narrow, membranaceous ; achenia obovate, not stipitate, the apex
mucronate with a short acute cone.—DC. ! prodr. 5. p . 692. H. congesta,
Hook. Sf Am . bot. Beechey, suppl. p. 355 ?
California, Douglas !—There appears to be some difficulty in distinguishing
these two species by the description. What we have as H. angustifolia
agrees with the character of De Candolle, except that the leaves (at least the
upper) and the scales of the involucre are clothed with both villous and glandular
hairs (just as H. congesta is described); and the chaff is membranaqeo-
foliaceous. The stipe of the achenium and the terminal areola doubtless
vary with age. The (yellow) rays, about 12 in number, are slightly exsert-
ed, with the branches of the style very long and filiform: the tube of the disk
corolla glandular, as in most species of the genus, and the teeth hispid-
bearded on the margin. The leaves are about half an inch long, and obtuse.
5. H. congesta (DC.): stem herbaceous, erect, branching; the branches
somewhat hispid with soft glandular and glandless hairs; leaves linear-lanceolate,
sparsely villous-glandular; heads bracteate, crowded; chaff of the receptacle
somewhat coriaceous, foliaceous; achenia obovate, obtuse at the apex,
when mature produced at the base into a rostrate stipe, which is strongly
recurved, and bears a white areola. DC. 1. c.—H. multicaulis, Hook. 8c
A m . 1. c. 1
California, Douglas.—Of this we have no specimen, if our H. angustifolia
be the true plant. The H. multicaulis, Hook Sf Am., which is doubtless the
same with one or the other of these species, is said to have an annual or
biennial root; the stems somewhat simple, or corymbosely branched at the
summit, hirsute with soft spreading hairs; the radical leaves linear-lanceolate,
serrulate, several-nerved; rather glabrous; the cauline somewhat villous,
long and linear, the lower opposite and serrulate ; the heads bracteate
and in clusters of 2-3: the achenia obovate, obtuse, with an inflexed rostelli-
form stipe ; the chaff only a marginal series.
§ 4. Heads many-flowered, nearly solitary: receptacle chaffy throughout; the
chaff, with the scales of the involucre and the upper leaves, subulate-spines-
cent: pappus none.
6. H.pungens: herbaceous, somewhat ligneous at the base; stem sparingly
branched, setose with whitish hairs; leaves crowded; the lower pinnatifid,
with oblong or oblong-lanceolate spinose-mucronate lobes; the upper and
those of the axillary fascicles linear, entire, rigid, spinescent, the recurved
margins papillose-hairy; heads somewhat solitary, bracteate ; scales of the
involucre spinescent, glandular, nearly equalling the 2-cleft rays ; achenia of
the ray gibbous, with a terminal very oblique areola; receptacle wholly
chaffy ; the chaff lanceolate-subulate, spinescent. Hook. 8f A m .—Hartmannia?
pungens, Hook. Sf Am . bot. Beechey, suppl. p. 357 ; Hook. ic. pi.
t. 334.
California, D o u g l a s “ This is a very remarkable plant, more like a
species of Navarettia among the Polemoniaceae than one of the present order.
We can find no trace of it in De Candolle’s Prodromus.” Hook. 8f Am .
§ 5. Heads few-many-flowered, not bracteate, corymbose: receptacle chaffy
throughout; the scales of the outer series united: pappus none: leaves
glandless, entire or serrulate: flowers white ?
7. H. filipes (Hook. & Am.) : stem suf&uticose, erect, simple, hirsute with
soft hairs ; leaves linear, entire, 1-nerved, somewhat hirsute with soft hairs,
not glandular; the lower elongated, acuminate, with smaller ones fascicled
in their axils ; the upper much smaller and bractieform, with black glands ;
corymb loose ; the rather rigid branches filiform and glabrous; heads solitary
on long pedicels, few-flowered; scales of the o'bconical ebracteate involucre
few, hirsute; achenia oblong, attenuate at the base. Hook. 8f Am . bot.
Beechey, suppl. p. 356.
California, Douglas.—“ The corymb is lax, the primary branches bear a
few glanduliferous bracteas or leaves ; but the stalk that supports the capitu-
lum is slender, quite naked, and rigid. In habit it is very dissimilar to the
other species.” Hook. Sf A m .—This species, which is unknown to us,
would seem to have many points of resemblance to the Osmadenia tenella
of Nuttall.
8. H. luzulcefolia (DC.): stem erect, tomentose-canescent, corymbose at the
summit; the branches and the involucre hirsute and somewhat viscid ; leaves
linear-lanceolate, silky-villous, not glandular ; the lower elongated, tapering
to the base, denticulate, 3-5-nerved, sometimes opposite; involucre hemispherical,
many-flowered, nearly bractless ; achenia of the ray obovate, obcompressed,
somewhat gibbous, with a terminal obtuse sessile areola; those
of the disk abortive.—DC. ! prodr. 5. p. 692. H. sericea, Hook. Am.
bot. Beechey, l. c.
California, Douglas.—Perennial? herbaceous, 8-12 inches high. Lower
leaves 4-5 inches long, 3-4 lines broad, and not unlike those of a Luzula ;
the appressed silky pubescence becoming loose and villous-tomentose on the
old leaves, at length somewhat deciduous: those of the branches or loose corymb
one-fourth to half an inch long. Heads 3-4 lines broad ; the scales of
