Dr. Todd. Dr. Richardson. Drummond. Douglas.—The plant here characterised, is the acknowledged
T. cordifolia of all American Authors. A comparison of it with the figure of Gmelin, will show
that it is the same with his species; consequently the M. nuda of Linnaeus, and among the numerous
specimens gathered by the Travellers just-mentioned, many throw out runners, which, again, bearing leaves
and scapes, the plant becomes the M. prostrata of Michanx-

loides. De Cand. Prodr. v. 4. p. 50.
Hab. Moist alpine woods in the Rocky Mountains. Drummond.—I can by no means agree with my learned
and valued friend, De Candolle, that this should form a genus distinct from Mitella diphylla and M. nuda. In
habit, they so entirely correspond, that it would be offering a violence to nature to separate them. Our plant
only differs, generically, in the suppression of the five stamens that are opposite the lobes of the calyx, and in the
union of the ovary for nearly its whole length; which latter circumstance is very variable, as we have
shown in the allied genus Heuchera: and the reduced stamens exist equally in the following species, where
the ovary is only half inferior:—there is this difference, however, that while in M. pentandra, the five remaining
stamens are opposite the petals, in M. trifida they alternate with them: but even if the present should
prove a distinct genus, the name Drummondia was previously established as a genus of Mosses. (Musci
Americani. v. 1, 1828, n. 62.)
4. M. trifida; pentandra, foliis radicalibus cordatis obtuse lobatis crenatis, scapo aphyllo,
calyce campanulato, limbo apice patente, petalis trifidis, ovariosemiinfero. (Tab. LXXXII.)
—Graham, in Ed. N. Phil. Journ. June, 1829.—M. parviflora. Douglas, MSS. apud
Herb. Hort. Soc. Lond.
Radix perennis, crassa, fibrosa. Folia omnia radicalia, longe petiolata, cordato-rotundata, lobata; lobis
brevibus obtusis crenatis, supra pilis albis rigidis appressis, subtus nuda. Petioli pilis rigidis deflexis asperi.
Scapus spithamseus ad pedalem et ultra, aphylla, nuda vel squama parva una alterave instructa. Racemus
subspicatus, gracilis, demum elongatus. Pedicelli brevissimi, bractea minutissima lineari quandoque suffulti.
- Calyx campanulatus, parvus, tenuissime pubescens: tubo supeme libero 5-fido, laciniis ovatis fere albidis, ad
apices patentibus. Stamina ad oram tubi inserta, inclusa, laciniis opposita. Filamenta brevissima. Antherce
subglobosse. Petala patentia, parva, unguiculata, cuneata, profunde bifida. Ovarium semi-superum: Styli
2 breves. Stigmata capitata. Capsula calyce tecta, unilocularis, bivalvis, polysperma: valvis arete reflexis.
Semina nigro-fusca.
Hab. Alpine rivulets, North of the Smoking River, on the East side of the Rocky Mountains, in lat.
56°, rare. Drummond. Plentiful in woody situations on the low ridge of the Blue Mountains of Lewis
and Clarke’s River, West of the Rocky Mountains, in lat. 46°. Douglas.—This has petals similar to those of
Tellima parviflora. Here, as I have already intimated, the five stamens are opposite to the segments of the
calyx: and sometimes they are wholly wanting. Again, in other plants cultivated in the Botanic Garden,
the petals were wanting altogether, so that little dependence can be placed on the number of these parts in
constructing the generic characters.
