I do not think that the genus Brachystemum Micha. can be separated from this one. .

The Satureia Thymbra Linn. has the stamina approximate under the upper lip, and 
must therefore be excluded from this genus. The section Thymaria (Dec. et Duby bot. 
gall. p. 370) cannot, in my opinion, be distinguished from Thymus. The section Sabattia, 
Mench, forms my genus Micromeria. The genus Satureia would thus be confined to the 
S. hortensis, montana, and perhaps one or two others among those which I have not yet 
had an opportunity of examining. 
17. Micromeria. Benth. — Flores verticillati vel capitati. Calyx 10- vel 15-striatus, 
tubulosus, dentibus 5 subzqualibus, intüs fauce villosá. Corolla tubo calycem sub. 
sequante, bilabiata, labio superiori erecto plano emarginato, inferiori patente trifido. 
Stamina 4, distantia. Antherarum loculi paralleli. 
This genus comprehends the Sabattia of Moench (a name which I could not adopt, on 
account of the older genus of the same name in the order of Gentianez), and most of 
the species of Persoon's section Zygis of the genus Thymus; probably also the South 
American Bystropogons with verticillate flowers. i 
18. Thymus. Linn. — Flores verticillati vel capitati. Calyx 10-striatus, ovato-tubu- 
losus, bilabiatus, labio superiori 3-dentato, inferiori bifido, intùs fauce villosà. Corolla 
tubo calycem subequante, bilabiata, labio superiori erecto subplano emarginato, inferiori 
patente trifido. Stamina 4, distantia. Antherarum loculi paralleli. 
This genus would thus be reduced to Persoon's section Serpyllum. 
19. Origanum. Linn.—Florum spice tetragone, strobiliformes, bracteis imbricatis. 
Calyx varius. Corolla tubo calycem subzquante, bilabiata, labio superiori erecto sub- 
pese BO, inferiori patente trifido. Stamina 4, distantia. Antherarum loculi

These six genera are so closely allied as to be scarcely distinguishable. The corolla 
and stamina are nearly the same in all, the length of the stamina being too variable even — ^ 
in the same species to serve as a generic character. "The inflorescence and calyx alone, 
characters of minor importance in the order of Labiate, can serve to separate them.

21. Hyssopus. Linn.— Calyx tubulosus, subequalis, 5-dentatus. Corolla tubo calycem 
subequante, bilabiata, labio superiori erecto emarginato, inferiori trifido : lobis lateralibus 
suberectis, medio emarginato subbifido, laciniis divergentibus. Stamina 4, exserta, dis- 
tantia.  Antherarum loculi lineares, divaricati.”
