probably first made known to botanists. Leonurus, indeed the same species, L. Sibericus, 
is found in Europe, Northern Asia, Africa, and America; it occurs both in the plains 
of India and in the Himalayas. pa 
Of species which extend from the southern to the northern parts of India, Anisochilus 
carnosus and Leonotis nepetafolia, may be mentioned as common on the banks of the 
Jumna and in the interior of the mountains. Leucas procumbens and L. urticefolia 
occur in Bundlecund, and the latter also in Arabia and Abyssinia. Anisomeles Heyneana 
spreads from the Peninsula to Salsette. Coleus barbatus is found in the mountains of 
the Peninsula, and of Arabia Felix, in Nepal, Kemaon, and near Kedarkanta. 
Moschosma polystachya and Coleus scutellaroides extend to New Holland; Acrocephalus 
capitatus, Leucas chinensis and mollissima, with Anisomeles ovata, spread eastward into 
China. Ocimum canum and basilicum, Leucas martinicensis, exist also in Africa and 
America ; Leonotis nepetefolia in the former only. Salvia acaulis and plebeia, belonging 
to sections found in Africa and also in America, are both indigenous in the plains of 
India. S. plebeia occurs also in tropical Asia generally, in China, and New Holland ; 
it extends north in India to the banks of the Jumna. 
The genera, on the contrary, which are found in the Himalayas, display, as we 
should expect from the differences ih climate, affinities in vegetation to very different 
countries. Those which are peculiar to these mountains, are Perilla, Marmoritis, 
Roylea, Notochete, Eriophyton, and Colquhounia. Holmskioldia keeps to the jungly 
base. Plectranthus, Meriandra, Craniotome, ave genera of which some of the species 
are seen in these mountains, but others in hot parts of the world. Salvia, 
Prunella, Stachys, Leonurus, Teucrium, and Ajuga exist almost every where, except 
the last, which is not found in America; and Scutellaria every where, but in tropical 
and Southern Africa. The above, therefore, do not prove analogies in vegetation. 
Elsholtsia and Eremostachys are common to the north of Asia and the Himalayas. 
Mentha, Melissa, Dracocephalum, and Lycopus chiefly inhabit the temperate parts of 
Europe, Asia, and America; the last has also one species in New Holland. Hyssopus, 
Lamium, and Marrubium exist in Europe and Northern Asia. Of the last, one species 
extends to Cashmere, and one as far as America. Hedeoma is an American genus, 
of which one species has been found in the Himalayas. Origanum, Thymus, Phlomis, 
Ballota, chiefly occupy Europe and the Mediterranean region. The Himalayas appear 
to be the head-quarters of Nepeta, as five species were discovered by Dr. Wallich, eleven 
by the Author, and ten additional species by M. Jacquemont, of the latter, NV. gluti- 
nosa exists also in Mr. Inglis’s collection. 
Hyptis is a vast American genus, of which a few species spread to the Old World, 
perhaps not originally indigenous, as H. spicigera and pectinata, found in tropical Africa, 
and the last also in Asia; but H. obtusifolia, Br., is a new, though undescribed species, 
found by Mr. Salt in Abyssinia. H. nepalensis Lehm, is not known to Mr. Bentham, 
‘but H. suaveolens was brought me by my plant collectors; they stated from the Choor
