Not only the corolla of the ray flowers but also that of the outer disc flowers
is corky at base after flowering; only the ray flowers and some of the outer
disc flowers are fertile; the greater part of the disc flowers are fertile though
apparently well formed. their style is divided, but mostly shorter than
that
the corolla, only the style of the innermost is undivided, imperfect.
Achenia sulcate, sparsely hairy.

(Have you seen Keerlia skirrhobasis D.C.? and may not this be
his plant? but Pappus cleft in many nearly sebaceous short segments

112 Gnaphalium purpureum Lin var. spicatum (G. spicatum
Lam?)
Inner scales apparently not purple; tomentum on the lower surface of
the leaves closely adpressed silvery.

115 Pyrrhopappus carolinianus DC.
116 Lobelia glandulosa Walt In wet praries and woods, in September; a
more or less scabrous form; bracts from a broad base lanceolate; sinus
of calyx very slightly reflexed. Specimens collected in shady places are
less rough; tube of calyx is hispid or nearly glabrous. — Another form
collected in April in wet praries is nearly smooth and has linear-lanceolate
leaves.

feet high, in brakish swamps near the coast, and in fresh water swamps. Root
tuberous.

120 Sabbatia {Sabatia} campestris Nutt (I have no description at hand but have seen a
specimen, so labeled with you, which I think is the same. — I have collected
the same plant in Arkansas and Louisiana) in April & May and
again in August & September — annual.
121 Sabbatia {Sabatia} phyllocalyx n sp. [calycosa, ex Torr.] annua, caule suberecto flaccido simplicis [?],
brachiato — ramoso, subangulate, follis ovato — lanceolatus trinerviis,
inferioribus obtusis in petiolum attenuatis, superioribus sessilibus
acutius culis; calyx 5—partito laoiniis foliaceis, oblanceolatis
corollam 5-partitam superantibus; lobis corollae obovatis obtusis.

Shady margins of streams near Houston, May & June.
An annual plant with a week stem, thin membraneous leaves
and very large leafy lobes of calyx; corolla smaller 8-9 lines
in diameter, pule rose colour, white when dry. Principally distinct
from the nearly related S. calycosa by the much smaller and
constantly 5 parted corolla and by the lower leaves being petioled.

minor. This is a smaller
form, with a somewhat looser inflorescence, and earlier time of flowering; it
grows on drier spots, mostly on Petalostemon multiflorum {multiflorus}, but also on
Liatris
and even on Euphorbia corollata. It approaches to C. hispidula Engelm. and it
is not improbable that further investigations of the living plants will prove
both to be only varieties of one very variable and in Texas widely dispersed
species, for which we would suggest the nameC. porphyrostigma as all
