Among the specimens which I have had occasion to examine, the following species may 
be referred to this genus : — 
1. L. chinensis. Hyssopus lophanthus. Linn. 
The corolla of this species is described as resupinate ; but that is not the case at least 
with a specimen from Dahuria sent to Mr. Lindley by Dr. Fischer of Petersburgh. 
2. L. urticifolius. . Hyssopus. urticifolius. ‘Douglas. 
L. glabra, foliis cordato-ovatis obtusis crenatis, verticillis densè spicatis, laciniis 
lineari-subulatis, genitalibus longè exsertis.— A larger species than the others of the 
genus. Flower-spikes terminal, dense, ovate; flowers of a pale purple, nearly as large 
as in the L. chinensis. Introduced by Mr. Douglas from the north-west coast of America. 
3. L. nepetoides. Hyssopus nepetoides. Linn. 
4. L. scrofularisfolius. Hyssopus scrofulariefolius. Willd. 
5. L. anisatus, t. 1282. 
6. L. multifidus. Nepeta multifida. Linn. — From Siberian specimens received by 
Mr. Lindley from Dr. Fischer. 
The Labiate with divergent stamina, to which section this genus belongs, might be 
grouped into two tribes, the Menthoidee and the Satureinee ; of which I take this oppor- 
tunity of giving the characters, as also of enumerating the genera, along with the charac- 
ters of such as are new, and amended characters for those which appear to me to require 
modification. >

I have dedicated this genus to my friend M. Audibert, of Tarascon, proprietor of one 
of the most extensive Nurseries in France, who has introduced and naturalised many 
rare and valuable exotics, and who, in 1820, accompanied M. Requien in his Botanical 
tour in Corsica, where they first discovered the plant which constitutes this genus. 
5. Mentha. Linn. —Calyx equalis, 5-dentatus, intüs fauce nuda, vel rariùs villosa. 
Corolla tubo brevissimo, subequalis, 4-fida, Stamina 4, distantia, exserta, vel inclusa. 
Filamenta nuda. Anthere 2-loculares, loculis parallelis. 
This genus thus reduced comprises the European, North American, and Siberian 
species, the M. Royleana Wall. cat. herb. ind. no. 1537, and probably also Mr. Brown’s 
New Holland species, and the M. javanica of Blume. I have also observed in Mr. 
Lindley’s Herbarium two new species of true Menthas from Ceylon. | 
- Colebrookia. Roxb. — Calyx equalis, 5-partitus, plumosus, maturatione papposus, 
carpellis adherens. Corolla subzqualis, 4-fida, lobo superiori emarginato. Anthere 4, 
subsessiles, 2-loculares, loculis parallelis. 
Spec. 2. €. oppositifolia et ternifolia. Roxb. 
7. Perilla. Linn.—Calyx per anthesin subequalis, 5-fidus, post anthesin 2-labiatus, 
labio superiore dilatato 3-lobo, inferiori 2-fido. Corolla subequalis, 5-fida, lobis 3 supe- 
rioribus, 2 inferioribus. Stamina 4, distantia, corollam equantia. Anthere 2-loculares,

8. Acrocephalus. . Benth.—Calyx tubulosus, basi subgibbus, 2-labiatus, labio superiori 
ovato plano integro, inferiori 4-fido. Corolla calyce brevior, subaqualis, 5-fida, lobis 
3 on Sa 2 inferioribus. Stamina 4, brevia, distantia. Anthere 2-loculares, loculis 
parallelis. 
Spec. A. scariosus. Benth. in Wall. cat. herb. ind. no. 1563. I think it probable 
that the Ocymum capitellatum Linn., and Ocymum acrocephalum Blume Bijdr. p. 384, 
belong to this genus.
