58 FLORA OF WASHINGTON AND VICINITY.<br />
the pursuit of this branch of science the environs of the <strong>National</strong> Capi-<br />
tal are in a high degree adaj)ted. Science and culture must go hand in<br />
hand. Culture must become more scientific, and science more cultured.<br />
Botau}^ has an important part to perform in this work of reconciliation,<br />
and there is no good reason why Washington may not become one of<br />
the foci from which these influences are to radiate. It has been such<br />
reflections as these, aside from the practical needs for such a work, that<br />
have encouraged me to persevere in this humble, indeed, but not the<br />
less laborious task, and if it shall be found useful, to however slight a<br />
degree, in promoting these worthy objects, no regrets will ever arise at<br />
having undertaken it.<br />
XIV. EXPLANATIONS.<br />
The catalogue which follows, with the accompanying remarks on the<br />
several species, will be better understood by attending to the following<br />
explanations:<br />
1. The habitat of plants is not specified unless it is in some way pecu-<br />
liar or dift'erent from that given in the manuals.<br />
2. Localities are given only of plants that are confined, so far as<br />
known, to a single spot or to the particular places named in connection<br />
with them. When the locality is omitted, therefore, it may be inferred<br />
that the plant is common, at least in such situations as constitute its<br />
natural habitat.<br />
3. The word "rare," said of a plant whose locality is not stated, sig-<br />
nifies that there is no j)articular place where the collector can be sure<br />
to find it, although it may have been sparingly found in several places.<br />
Attached to a stated locality, the word "rare" implies that the plant is<br />
rare, and perhaps no longer obtainable, in that locality. Localities<br />
given without this word may be depended on to furnish the plants.<br />
4. The general designations, "Reform School," "Terra Cotta," &c.,<br />
embrace the regions in the vicinity of these points, as more fully de-<br />
scribed in the introduction.<br />
5. Where a plant has only been found once or quite recently, if dis-<br />
covered by a botanist other than the author, the name of the discoverer<br />
is stated, inclosed in parentheses. Credit is thus sought to be given to<br />
the true discoverer of all new additions to the flora.*<br />
* Of the 213 additions which have been made to the flora of this vicinity since the<br />
publication of the catalogue of 1876, 160, or over 75 per cent., have been the result of<br />
the author's own personal investigations.
