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

 corolla? tubo calycem superante, labio superior! brevi inferiori trilobo lobis lateralibus rotun- 

 datis valde concavis intermedio recto mucr oniformi. 



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 bag is the testa. 



Ord. XXXIII. LABIATE. Juss. 



1. 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 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 bractete 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 piperita. Linn. — Engl. Bot. t. 687. 

 Most probably an introduced plant. 



1. Stachys ajngoides; caule erectohumili villosissimo, foliis petiolatis oblongis obtusissimis 

 crenatis basi rotundatis pilis subsericeis villosissimis floralibus sessilibus conformibus calyces 

 superantibus, verticiUastris sex-floris, bracteis subnullis, calycibus sessilibus campanulatis 

 villosissimis dentibus ovatis brevissime aculeatis, corollas tubo calycem subduplo superante 

 labiis patentibus superiori 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, verticiUastris sexfloris distantibus, 

 calycibus subsessilibus tubulosis hispido-pilosissimis dentibus ovatis acuminatis subpungenti- 

 bus, corollae tubo recto calyce subduplo superante labio superiore villosissimo. 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 bi-eve piloso, verticiUastris billoris distan- 

 tibus, calycibus subsessilibus folio florali triplo brevioribus tubulosis pilosissimis dentibus ovatis acuminatis 

 pungentibus. — This, if new, may be called S, bijiora.
