than the bracteas or floral leaves : they are generally shorter than the floAver, while in M. luteus the loAver
ones especially are often considerably longer. What Sprengel means, Avheu he says that iu the one the
peduncles have bracteas, and in no other are ebracteate, we scarcely comprehend.
2. Mimulus/or¿6w«í?«5; annuus, caule prostrato villoso, foliis bracteisque consimilibus
petiolatis cordato-ovatis acutis denticulatis glabris plurinerviis, pedunculis pubescentibus
bractea sublongioribus calyce urceolato pubescenti dentibus acutis subæqualibus.—Lindl.
Bot. Reg. i. 1125.
This quite agrees with Mr. Menzies’ original specimens from the same coast.
3. Miinulus glutinosus; glutinosas, caule erecto suffruticoso, foliis sessilibus elliptico-
oblongis acutiusculis obscure dentatis subtus pubescentibus pedunculis calyce tubuloso duplo
brevioribus.— Willd.— M. aurantiacus. Bot. Mag. t. 354.
1. Castilleja affinis; caule herbaceo subsimplici piloso-hispido, foliis lineari-lanceolatis
trinenuis pubescentibus integris, floralibus linearibus integris vel (raro) apice deiitato-lobatis,
floribus inferioribus pedunculatis, calyce florífero tubidoso antice posticeque fisso lobis bifidis
segmentis Imeari-lanceolatis acutis, corolla calycem superante.
I t Avill be seen from the above character, taken from the Californian specimens, that there are considerable
points of difference betAveen them and the C. pallida of authors, the Bartsia pallida of Michaux. The
floral leaves, not dilated, also separate it from C. lithospermoides of Kunth. From C. integrifolia, Linn,
to Avhicb it is also allied, the tubular, not ventricose, calyx, during floAvering, will keep it distinct.
2. C a s t i l l e j a c a u l e subherbaceo ramoso inferne subhfrsuto pubescente superne
subvilloso, foliis ovato-oblongis obtusis integris dense pubescentibus, floralibus dilatatis
cuneatis apice trifidis lobis brevibus obtusis medio latiori, floribus subsessilibus, calyce
fiorifero tubuloso antice postice æqualiter fisso lobis breviter obtuse bidentatis, corollæ tubo
calycem æquante.
According to Mr. Collie this is from three to six inches high, and grows in wet sandy places : he mentions
that the flowers are in a lax terminal spike; but, AAdth the exception of one specimen, in which the bracteas
have fallen away, those in the Collection exhibit a spike which is both short and dense. Chamisso appears
to have fonnd in the same place, “ in arenosis littoralibus ad portum S. Francisci Novae Californiæ,” a
species which surely must be the same with ours, but which he refers to C. Toluccensis, H. B. K., owing,
perhaps, to his having only seen “ serótinas autumni proles.” This and the next must belong to the same
subgenus or section of Castilleja as Euchroma coccinea, Nutt, having the same kind of calyx, while C.
affinis has more the calyx of Euchroma grandiflora.
3. Castilleja foliolosa; niveo-tomentosa, caule fruticoso ramoso, foliis confertis inferioribus
linearibus obtusis superioribus floralibusque divaricato-tripartitis rariusv'e integris, floribus
subsessilibus, calyce florífero tubuloso antice postice æqualiter fisso lobis leviter emarginatis,
corollæ tubo calyce breviore.
From two to three feet high, according to Mr. Collie, who found it in a clayey soil, in hilly situations.
In some points it approaches tp C. flssifolia, L. The axils of the leaves are furnished with a tuft of leaves
on short abortive branches.
4. Castilleja ambigua; pubescens, annua, caulibus plurimis subramosis, foliis sparsis inferioribus
lanceolatis obtusis superioribus floralibusque sensim majoribus dilatatis profunde
multifidis, calyce fiorifero tubuloso subæqualiter fere ad medium quadrifido laciniis subulatis
corollæ tubo calycem superante, labio superiori brevi inferiori trilobo lobis lateralibus rotundatis
valde concavis intermedio recto mucroniformi.
Bartsia tenuifolia, Pursh, seems closely allied to this species. Tbe lower lip of the corolla is quite at
variance with the character a t present given of the genus, yet the upper lip, and the whole habit of the
plant agrees with it. The upper lip is so short, that when the lower is pressed against it, the two are nearly
of the same length. At each side of the central lobe of the lower lip is a small gland, as in several other, if
not all the species, of Castilleja. The seeds are oblong, acute a t each end, and enclosed in a loose reticulated
membranous bag, from which, when it is cut, they faU out. Perhaps, however, this bag is the testa.

L Thymus Chamissonis; caule procumbente ramoso pubescente, foliis petiolatis ovatis
obtusis crenatis subtus nervosis glanduloso-punctatis, pedunculis axillaribus solitariis oppositis
folio brevioribus basi setaceo-bibracteolatis, calycibus vix bilabiatis intus fauce subnutlis
fructiferis inflatis dentibus setaceis, corollis calyce duplo longioribus. Benth. in Lin næa , v.
6 . p . 80.
The leaves are almost an inch long, and nearly the same in breadth. The bracteæ in the same specimen
are sometimes situated near the middle of the peduncles, hence we have doubts if T. Douglasii, Benth. 1. c.
said by Mr. Bentham to have been also found in California, and only to differ by the broader foliage and
different situation of the bracteoles, be really distinct.

Most probably an introduced plant.
1. Stachys ajugoides; caule erecto bumili villosissimo, foliis petiolatis oblongis obtusissimis
crenatis basi rotundatis pilis subsericeis villosissimis floralibus sessilibus conformibus calyces
superantibus, verticillastris sex-floris, bracteis subniiUis, calycibus sessilibus campanulatis
villosissimis dentibus ovatis brevissime aculeatis, corollæ tubo calycem subduplo superante
labiis patentibus superiori oblongo. Benth. in Linnæa, v. 6. p . 80.
Mr. Bentham farther mentions it to be from three to four inches high. Tbe only specimen in the Collection
is about eight inches : it differs slightly from the above character, by tbe leaves not only being
not rounded at the base, but decidedly acute.
2. Stachys Chamissonis; caule erecto tetragono angulis pilis rigidis obverse aculeatis,
foliis ovatis obtusis crenatis basi cordatis limbo utrinque vclutino-lanato, petiolo pilosissimo,
floralibus sessilibus ovato-lanceolatis calyce brevioribus, verticillastris sexfloris distantibus,
calycibus subsessilibus tubulosis hispido-pilosissimis dentibus ovatis acuminatis subpungcnti-
bus, corollæ tubo recto calyce subduplo superante labio superiore villosissimo. Benth. in
Linnæa, v. 6. p . 80.
