Leucodon

This genus is chiefly confined to Europe & north america. But there are a few species, formerly numbered under this genus, but now made into separate genera, that are found in the southern hemisphere. Two species also still retained in Leucodon, but very dissimilar to it in appearance are also found, the one in Peru ? (vide Leucodon Tomentosus  Kunth 1822–1825, I, 53.

 [Schließen]Humboldt & Kunth. Synopsis), the other in New Holland. Leucodon canariensis, now an Astradontium is found both in Teneriffe & the isle de Bourbon.

Neckera .

Like all the other Hypnoid genera this is widely diffused. Neckera crispa is found in Europe, North & South america, Teneriffe, and probably found every where: Neckera cladorrhizans is common to Europe & North america, & is I believe met with in Nepal – Neckera dendroides originally found in the Sandwich isles also occurs in Nepal. – Neckera viticulosa is common to Europe & North america.

Daltonia .

Only three species are found in Europe, & one of these Daltonia pennata is found also in North america, Jamaica, Guiana & Isle de Bourbon, & probably in several places in the Southern hemisphere, of the other species (16 or 18) Daltonia undulata is found in Jamaica, South america, and many other tropical countries, the others are chiefly local.

Spiridens

Found in the isle de Bourbon, and in Java.

Hookeria.

With the exception of a fewspecies, and there are about 35 known, this genus may be said to be tropical. Hookeria lucens is found however in Europe & North america; but we believe no other species has yet been found there. Hookeria magellanicaoccurs at the straits of Magellan, & Hookeria cristata & Hookeria Tamarisci are only found in New Zealand. – but the localities of some species are not precisely known. The most widely diffused species is the Hypnum Tamarisci of Swartz, (but not of Hedwig.), it is found in Jamaica, South america, isle de Bourbon, Nepaul &c.

Hypnum.

Of this genus it is impossible to give any account: Most authors at present are in the habit of making plants from remote localities distinct if they have a slight difference in appearance: it is my opinion however in this genus in particular that soil & climate will make the same species vary so much that it can scarcely be recognized.

To avoid disputes it may be better to say generally that
