This genus, although referred by Sir J. E. Smith to the Verbenacem, and by Don (Prodr. fi. 
nepal. p. 2 to the genus Clerodendron, belongs undoubtedly to the order Labiatz, and is 
indeed scarcely distinguishable from Teucrium. In habit it comes nearest to T. hyrcanicum. 
"The structure of the flower is so nearly that of T. heterophyllum Desf., that if the genus be 
retained, the latter md te should probably be added to it. 
25. Teucrium. Linn.—Calyx tubulosus, ovatus v. campanulatus, 5-fidus v. 5-dentatus, sub- 
æqualis v. bilabiatus. Corolle tubus calyce subbrevior; labium superius bipartitum, laciniis 
demissis : inferius patens, 3-fidum. Stamina 4, ascendentia, è fissurà labii superioris longè exserta. 
Antherz, loculis divaricatis confluentibus, subuniloculares. Stylus apice subzqualiter bifidus. 
Achenia reticulato-rugosa. 
This genus is easily subdivided into very natural sections, which, however, appear to me too 
closely connected to form separate genera. 
26. Amethystea. Linn.—Calyx campanulatus, subzqualis, 5-fidus. Corolle tubus calyce 
brevior, labium superius bipartitum : laciniis demissis, inferius patens, 3-fidum. Stamina fer- 
tilia 2, ascendentia, è fissurá labii superioris longe exserta. Anthere biloculares, loculis 
divergentibus, demüm divaricatis subconfluentibus. Stylus apice subequaliter bifidus. Achenia 
reticulato-rugosa. - 
This genus only differs from Teucrium by the abortion of the two upper stamina. A.cerulea 
is most nearly allied to Teucrium orientale. 
27. Trichostema. Linn.—Calyx campanulatus, obliquè 5-fidus, resupinatus. Corolla, tubo 
calyce incluso, v. exserto incurvo, bilabiata : labio superiori integro falcato, v. bifido, lobis 
demissis: inferiori 3-fido, lobis lateralibus suberectis, medio patente. Stamina 4, ascendentia, è 
labio superiori longè exserta, falcata. Anthere biloculares, loculis demüm divaricatis. Stylus 
apice subequaliter bifidus. Achenia reticulato-rugosa. 
This genus is allied to Amethystea and to Isanthus, which latter genus ought perhaps to be 
brought to this tribe ; but my specimens are not good enough to enable me to ascertain precisely 
the direction of the stamina. i

labio superiori abbreviato erecto integro vel emarginato, inferiori majore patente trifido.

vel divaricatis subconfluentibus. Stylus apice subequaliter bifidus. Achenia reticulato-rugosa. 
29. Anisomeles. Br. — Calyx ovatus, subaqualis, 5-dentatus. Corolla tubo calycem sub- 
æquante, bilabiata, labio superiori abbreviato erecto integro, inferiori majore patente 3-fido.

Tribus 4. MoNARDEZ. 
Corolla subequaliter bilabiata. Stamina, 2 labii inferioris ascendentia, è labio superiori 
exserta vel ei subzequalia, antheris margine connexis; labii superioris abortiva v. rariùs fertilia, 
tubo subinclusa, antheris liberis. 
31. Monarda. Linn. — Calyx cylindricus, 15-nervis, subequalis, 5-dentatus, intüs fauce vil- 
losá. ‚Corolla tubo longè exserto, fauce subinflatä, bilabiata, labiis snbeequalibus ; superiori erecto 
lineari integro, inferiori patente 3-fido. Stamina fertilia 2, ascendentia, e labio superiori exserta. 
Anthere margine connexe, biloculares, loculis divaricatis. Stylus apice subzequaliter bifidus.

32. Blephilia. Rafin.—Calyx ovato-cylindricus, 10-nervis, intùs fauce nudá, bilabiatus, labio 
superiori 3-dentatus dentibus subulato-aristatis, inferiori 2-dentatus dentibus breviter aristatis 
vel muticis. Corolla tubo exserto, fauce inflata, bilabiata, labiis subwqualibus : superiori erecto 
lineari integro, inferiori patente trifido. Stamina fertilia 2, ascendentia, e labio superiori exserta. 
Anthere margine connex®, biloculares, loculis divaricatis. Stylus apice subzqualiter bifidus. 
Achenia sicca, levia. 
The Monarda hirsuta Pursh, belongs to this genus, as well as the M. ciliata Linn. or Blephilia 
ciliata Rafin. 
. 33. Zizyphora. Linn. — Calyx elongato-cylindricus, 15-nervis, subequaliter 5-dentatus, 
intüs fauce villosá. Corolla tubo calycem subequante, bilabiata, labiis subzequalibus : superiori 
erecto lineari integro, inferiori patente 3-fido. Stamina fertilia 2, ascendentia, è labio superiori 
exserta vel rariús eo subbreviora. Anthere margine connex®, biloculares, loculis divaricatis. 
Styli lobus superior brevissimus. Achenia sicca, levia. 
_ Cunila capitata Linn. appears to me to have been correctly referred to this genus, although 
in Z. capitata, hispanica, and tenuior Linn. the stamina are somewhat shorter than the upper p 
of the corolla; a circumstance, however, which, in this instance, I should consider of little 
importance. 
LE P Cunila. Linn. — Calyx tubulosus, 10-15-nervis, subæqualis, dentibus 5 margine vil- 
losissimis. Corolla _tubo calycem subequante, bilabiata, labiis subzequalibus : superiori erecto 
emarginato, inferiori patente 3-fido. Stamina fertilia 2, ascendentia, è labio superiori - 
e margine connexz (?), biloculares, loculis divaricatis. Stylus apice subinteger- Achenia

This genus thus restricted to C. mariana Linn., C. paniculata Benth., another N. American 
species unnamed in Linneus’s Herbarium, and C. /ythrifolia Benth., a Mexican plant iP 
Mr. Lindley's Herbarium, appears to me to belong to this tribe; although, on account of the 
manner in which the flowers are dried in the only specimen I have bad an opportunity of dis-
