multifidis, calyce florifero tubuloso subaequaliter fere ad medium quadrifido laciniis subulatis

Bartsia tenuifolia, Pursh, seems closely allied to this species. The lower lip of the corolla is quite at 
variance with the character at 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 at each end, and enclosed in a loose reticulated 
membranous bag, from which, when it is cut, they fall out. Perhaps, however, this hag is the testa. 
Ord. XXXIII. LABIATE. Juss. 
1. Thymus Chamissonis; caule procumbente ramoso pubescente, fol'iis petiolatis ovatis 
obtusis crenatis subtus nervosis glanduloso-punctatis, pedunculis axillaribus solitariis oppositis 
folio brevioribus basi setaceo-bibracteolatis, calycibus vix bilabiatis intus fauce subnudis 
fructiferis inflatis dentibus setaceis, corollis calyce duplo longioribus. Benth. in Linncea, v. 
6. p. 80. 
The leaves are almost an inch long, and nearly the same in breadth. The bractese 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. 
1. Mentha Linn. — Engl. Bot. t. 687. 
Most probably an introduced plant. 
1. Stachys ajugoides; caule erecto humili villosissimo, foliis petiolatis oblongis obtusissimis 
crenatis basi rotundatis pilis subsericeis villosissimis floralibus sessilibus confonnibus calyces 
superantibus, verticillastris sex-floris, bracteis subnullis, calycibus sessilibus campanulatis 
villosissimis dentibus ovatis brevissime aculeatis, coi’oUm tubo calycem subduplo superante 
labiis patentibus superior! oblongo. Benth. in Linncea, v. 6. p. 80. 
Mr. Bentham farther mentions it to be from three to four inches high. The only specimen in the Col- 
lection is about eight inches : it differs slightly from the above character, by the 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 velutino-lanato, petiolo pilosissimo, 
floralibus sessilibus ovato-lanceolatis calyce brevioribus, verticillastris sexfloris distantibus, 
calycibus subsessilibus tubulosis hispido-pilosissimis dentibus ovatis acuminatis subpungenti- 
bus, corollee tubo recto calyce subduplo superante labio superiore villosisshno. Benth. in 
Linncea, v. 6. p. 80, 
We have only seen one specimen, which is about two feet high, and nearly simple. There is also a 
fragment of an allied species in the Collection, too imperfect to be satisfactorily determined : its character, as 
far as we can draw it up, is as follows : — caule erecto gracili tetragono, angulis pilis rigidis raris reflexis 
hispidis, foliis supremis ovatis sessilibus floralibus subrotundo-ovatis basi subiter attenuatis omnibus crenato- 
dentatis dentibus rotundatis mucronulatis, limbo utrinque molliter breve piloso, verticillastris bifloris distan- 
tibus, calycibus subsessilibus folio florali triple brevioribus tubulosis pilosissimis dentibus ovatis acuminatis 
pungentibus. — This, if new, may be called S, biflora.
