A Lingua cervma folto undulate cnfpo; and 4· of a Lmgua cervina folio divifo crifpo undulate: but all thefe, and four ~r five others. re.corded as dif\:inCl: fpecies by Tournefort and others, are no more in reahty, than vanettes of. the common hart's tongue defcribed here, which fometimes grows. larger, fomettmes fmaller, and has it's leaves fometimes divided at the top, fomettmes curled at the edge. 3 . AJP!enium Jronde pinnata, folio/is fubrotundis cren~tis. <reng litlJ The pinnated AJP!enium, with roundifh, crenated jo!tola. .!l@attlett~air. This is a very beautiful little plant. It's root is compofed of a clu!l:er of fiender black fibres; from this there rife a great number of the plants together. Each rlant is fimple and pinnated : the !l:alk is round, £lender! ~la~k, and of a ver~ gloffy furf~ce ~ it grows up naked, for an inch or two; after thiS It .Is, to the extremity, ?efet With a donble feries of beautiful folioles. The whole plant IS ufually five or fix mches long, fometimes more. The foliola are of an oval figure, rounded at the end, and adhere to the f\:a\k without any pedicle; they !land oppofite, or nearly oppofit~, to one another, and the extremity of the !l:alk is terminated by a fingle leaf ~r fol.10lum. They are of a fine bright green colour, and fmooth fur face. The !l:a\~ IS bnttle. This fpecies is very. frequent in Englan~ on old ~~lls, and m other iliady pla~es. C. Bauhine calls it, Tnchomanes five polytnchum officmarum, p. 356. J. Bauhme, Trichomanes five polytrichum, 3· 7 54; and others, Trichomanes mas, and vulgare. The leaves or foliola of this fpecies are fometimes even, fometimes ferrated at the edges; and the plant grows fometimes larger, fometimes fmal.ler, a?d is fometi~~s fimple, fometimes divided into two or more p~rt~ at the e.xtrem.lty, like the Phylhus. Authors have defcribed thefe feveral vaneties of thts fpectes under the names of fo many fpecies. The Trichomanes foliis eleganter incifis, of Tournefort; the Trichomanes minus et tenerius, of C: Bauhine ; and the Trichomanes ramofum of the fame, and other authors, are no other than the varieties of this fpecies. 4· Afplenium Jrondibus alternatim decompojitis,Joliolis cuneiformibus crenulatis: The Afplenium, with alternately decompound branches, . and crenated, cuneiform leaves. nttnll laue. This is one of the fmallefl: of the fern-kind. It's root is compofed of feveral fine and· fma\1 black fibres, varioufly interwoven one with another. From this arife a great number of 11:alks or feparate plants ; thefe are feldom more than two inches in height, often not much more than an inch. The !l:alks' are dufky coloured, or blackifh, near the root, but higher up they are of a paler green ; they are divided, toward the top, into many ramifications, and at the extremities of thefe, and on their fid es, fiand little leaves, in fame degree, refemb\ing thofe of the true adiantum of the iliops. The whole plant together has been fuppofed to refemble a leaf of rue, whence it's common name Ruta muraria. The leaves are thick and rigid, obtufe at the extremities, and crenated : they are of a pale green on the furface, and brownifh underneath . This fpecies is frequent on old walls in England, and elfewhere. C. Bauhine calls it, Ruta mm·aria, p. 3 56. Tabernamontanus, Adiantum album, 796. 5· Afplenium Jrondi!Jus duplicato-pinnatis foliis inferioribus majoribus, folio/is obverfi ovatis, Juperne crenatis. The ramcfe Afplenium~ with cordated folio/a. JL;Iettlt ~atben~ batr. The root of this fpecies is com poled of a clufl:er of black and confiderabl y thick fi. bres ; from this there rife ufually fix or eight leaves together. The pedicle is rigid, ~ard, a~d of a black .colour, and fhining furface; it grows up naked to five or fix mches h1gh, and then 1t fends off a numPer of branches, which fiand regularly over- • againft The Hi}lory of P L A N T S. againfl:. one a~other, fo as to give the whole compound leaf a kind of triangular form, by thetr growm& iliorter all t~e way toward the top. Thefe branches are pinnated on each fide: the pmnules or fohola are deeply finuated , and fome rimes they are fubdivided into others ; they are bro~de O: at the lower part, and terminate in a poi nt. T he wh~le ~pper fur face of t~e leaf .1s of a dark green colour, the under fide is paler. This fpecieS IS very fr~quent w~th us ~n woods~ and oth~~ iliady places, about the fl:umps of tr.ees. C.
