Rnooth fegmcnts. Common ftalk round, briftly; partial 



winged, fmooth. Involucriim ftalked Native of tlie if]e 



of Bourbon. Our fpecimeu was communicated by M. 

 Thouin to the younger Linnxus, who took it ioxT.jlandens ; 

 but there is no appearance of any common trailing Jlem. 

 Tiie_/>-on(/ is almoli two feet high, ^/fl/i pale and fmooth 

 where naked, but in the leafy part of the_/;-on(^blacki(h and 

 hifpid. Divifions of the leciflets peculiarly fine, regidar and 

 delicate, bluntifh, fometimes emarginate, olive-green, with- 

 out any hairs. Involucrwn (hort and roundirti, on a ftalk 

 more or lefs winged ; its mouth fpreading. Column long. 



Trichomanes, in Gardening, comprehends plants of the 

 herbaceous fei-n kinds, — the maiden-hair ferns ; among 

 which, the fpecies which are cultivated for garden ufe and 

 variety, are the canary maiden-hair fern (!'. canarienfe) ; 

 and the Tunbridge maiden-hair (T. tunbridgenfe). 



Thefe are both perennial plants, which have fomething 

 curious and interefting in their frondofe growth and habit, 

 and are therefore proper to be cultivated for the ornament 

 and variety which they afford. 



Method of Culture. — Both thefe plants may be increafed 

 by flipping their branches, or dividing their roots, and plant- 

 ing them in pots of light earth in the firft fort, and the 

 latter kind either in the fame way, or in a dry border of 

 light mould, the former to be removed in the winter fea- 

 fon to the proteftion of the greenhoufe, but the latter to 

 remain where planted, or fome put into pots, to be placed 

 out in particular fituations, as occafion may require. 



They both fonii a Angular variety when put in aflem- 

 blage with other different plants of the exotic greenhoufe 

 forts, and other kinds in the borders and various com- 

 partments.

Gen. Ch. Cal. Sheath inferior, more than half the 

 length of the coroUa, of two lanceolate, entire, permanent 

 valves. Cor. of one petal, fuperior ; tube very (hort, 

 funnel-diaped ; limb regular, divided to its very bafe into 

 fix nearly equal, fomewhat fpreading, concave fegments. 

 Stam. Filaments three, inferted into the mouth of the tube, 

 ered, much fhorter than the coroUa, downy ; anthers rather 

 large, converging, oblong, cloven at the bafe. Pij}. Ger- 

 men roundifh ; ftyle thread-ihaped, ereft, longer than the 

 ftamens ; ftigmas three, deeply divided, equal, fpreading, 

 very (lender, rather abrupt. Per'ic. Capfule roundifh, 

 membranous, tumid, of three cells and three valves. Seeds 

 feveral, globofe. 



Eff. Ch. Sheath of two valves. Corolla with a very 

 ftiort tube, and equal regular limb. Filaments downy. 

 Stigmas three, deeply divided, very flender. Capfule 

 roundifh. Seeds globofe. 



Obf. The (hortnefs of the tube, divided ftigmas, and 

 pubefcent ftamens, diftinguifti this genus from IxiA. (See 

 that article.) The laft charafter is but (lightly perceptible, 

 and the others may perhaps hardly be thought fufficient to 

 feparate plants fo precifely alike in habit. We (hall never- 

 thelefs enumerate the fpecies as given by Mr. Ker, late 

 Gawler.

of graffy hillocks, and fandy ground near the fea, in the 

 fouth of Europe, from Jcrfey and Guernfey to the Archi- 

 pelago, in which laft country it is very abundant, flowering 

 in March and April. We have no where fecn this pretty- 

 plant more beautiful, witli its numerous varieties, than on 

 the hillocks around the celebrated fountain of Egeria, near 

 Rome. There all the different appearances of x\\e floiuer, 

 with refpeft to lize and colour, which the above figures re- 

 prefent, and indeed many more, may be collefted at once ; 

 nor can they fail to convince an obferving botanift that they 

 are no more diftinft fpecies, than our red or blue garden 

 anemonies. The bulb is ovate, the fize of a filberd, with 

 many entire fmooth coats. Leaves radical, recurved and 

 widely fpreading, narrow, fmooth, rufhy. Stalks one or 

 two, combined at the bafe, fingle-flowered, more or lefs 

 curved, round, fmooth, much ftiorter than the leaves, 

 though confiderably elongated after flowering. Slieatb 

 fomewhat coloured. Corolla from one to two inches long, 

 purplifh, pale rofc-coloured with a yellow bafe, or almoll 

 white in the border, always varioufly ftreaked ; the backs 

 of the three outer fegments greenvfli ; all the fegments elhp- 

 tical, but various in breadth. Capfule membranous, cor- 

 rugated, purplifh. We cannot feparate Mr. Ker's rofeum, 

 for which he cites Curt. Mag. t. 265, however different that 

 figure may, at firft fight, appear.

 in the former, various in breadth, but always known by 

 their four-fided figure, difplayed in a tranfverfe fcftion. 

 The Jalk is folitary, fhort and fimple. Corolla variable in

The leaves are ufually two, unequal, one of them decum-

 which bears a folitary leaf near the top.— Native of the 

 Cape of Good Hope, from whence Mr. G. Hibbert re- 

 ceived its bulbs in 1800. Thefe flowered in his garden at 

 Clapham the following March. This appears moft akm to 

 the firft fpecies in its leaves, except their being more ereft, 

 and fcarcely exceeding the length of the y/«H. The latter, 

 though fimple, bears one leaf near the top, according to 

 Mr. Andrews, who is our only authority. We arc aware
