THE DICTIONARY OF GARDENING, 



Asplenium continued. 



A. L Fernandesiannm (Fernandez).* A form with a more 

 rigid rachis and sub-coriaceous, rather narrower pinnae. Juan 

 Fernandez. 



A. macrocarpum (large-fruited), sti. bin. to 9in. long, fronds 

 12in. to 24in. long, 6in. to 12in. broad, ovate-lanceolate, with 

 numerous pinnae on each side, the lowest 3in. to 6in. long, lin. to 

 IJin. broad, lanceolate; pinnules oblong-rhomboidal, inciso-cre- 

 nate or pinnatifid. con copious, large. Himalayas. Greenhouse 

 species. SYN. Atkyrium macrocarpum. 



A. maorophyllum Gong-leaved). Synonymous with A. nitent. 



A. marginatum (margined), eti. 2ft. to 3ft. long, strong, erect 

 woody, about 4m. thick at the base, fronds simply pinnate, 4ft. 

 to 6ft. long ; pinnae in several opposite pairs, the lowest 1ft. to 

 2ft. long, Sin. to 4in. broad, the edge entire, the base often cor- 

 il.ite. sort long, linear, confined to the free veins. Tropical 

 America. Stove species. SYN. Ilemidiciyum marginatum. 



A. marinum (sea).* Sea Spleenwort. sti. tufted, Sin. to 6in. long. 

 fronds 6in. to 18in. long, 2in. to 4in. broad, oblong-lanceolate, apex 

 pinnutittd ; pinnae of the lower half quite deltoid, the point acute 

 or obtuse, margin crenato-dentate. sori broad, falling short of the 

 edge. Europe, including Britain. Although quite hardy, this 

 tlirives better in a frame or cool house than in the open air. 



(crowned).* fronds 4in. to 6in. long, simply pin- 

 nate ; pinnic for two-thirds of the way up variable in form, and 

 irregularly lobed and cut ; the upper third freely branched with 

 numerous imbricated, curled, and slightly crested divisions, form- 

 ing a dense head 2in. or more across. A dwarf and pretty 

 form. 



A. m. crenatum (crenated). fronds 4in. to Bin. long, broadly- 

 lanceolate ; pinnae nearly trapeziform, obtuse, with deeply cre- 

 nated margins. A very pretty form. 



A. m. mirabile (wonderful).* sti. 2in. to 4in. long, fronds about 

 the same length, the rachis divided about half way down from the 

 top into two nearly equal divisions, which are again freely forked, 

 with the pinnules and segments obtusely lobed ; the whole ex- 

 panded, but not crested, into a breadth equal to the length of the 

 frond ; the lower pinnae are more or less abnormal and bluntly 

 lobed. 



A. m. plnmosum (feathery).* tti. Sin. to 4in. long, fronds bin. to 

 15in. long, bi- or tripinnatifld, broadly-lanceolate ; pinnae very 

 variable, closely set, and imbricated, cut nearly to the rachis 

 into ovate or oblong divisions, which are again more or less 

 deeply cut and lobed, the entire frond having a very elegant 

 appearance. 



A. m. ramo plumosum (branched and feathery).*/r(mcfo divided 

 nearly to the top of the stipes into two main branches, which are 

 distinctly pinnate ; pinnae distant below, imbricated upwards, cut 

 nearly to the rachis into ovate or oblong lobes, the margins of 

 which are slightly dentated. It is a very handsome form, the 

 width of the frond being greater than its length. 



^m. ramosum (branched), fronds from 4in. to Sin. long, 

 ranched at the apices ; pinnae oblong, with the margins obtusely- 

 dentate, and slightly undulated. 



A. m. sub bipinnatum (half-bipinnate). frond* 6in. to 12in. long, 

 lanceolate ; pinnae distant, deeply lobed, or cut nearly to the mid- 

 ribs. A very rare and pretty variety. 



A. m. Thompson!! (Thompson's).* sti. 3in. to 4in. long, smooth. 

 fronds bin. to lOin. long, ovate-lanceolate, bipinnatifld ; pinnae 

 closely set, sub-deltoid, unequal-sided, deeply cut into oblong, 

 slightly undulated lobes below, gradually less divided upwards. 

 A very rare and handsome variety. All the forms of A. marinum 

 require a very moist atmosphere, consequently they will not thrive 

 in the open air, unless along the sea-coast. 



A. maximum (largest), eau. erect, sti. 2ft. or more long, frondt 

 several feet long, 2ft. to 3ft. broad, deltoid-lanceolate, with nume- 

 rous pinnae on each side, the lowest 9in. to 18in. long, 4in. to Sin. 

 broad ; pinnules sub-sessile, 2in. to 4in. long, Jin. broad ; edge more 

 or less lobed. sori medial, the lowest two lines long. North 

 India. Stove species. SYNS. A. diverstfolium and Diplazium 

 decurrens. 



A. melanocaulon (black-stiped).* tti. 1ft. to 2ft. long, fronds 

 2ft. to 3ft. long, 9in. to 18in. broad ; lower pinnae 4in. to 9in. long, 

 4in. to 6in. broad ; pinnules lanceolate, 2in. to Sin. long. Jin. 

 broad, cut down two-thirds of the way to the rachis into linear- 

 oblong, falcate, inciso-crenate lobes. tori short, oblong, not 

 touching either midrib or edge. Fiji. Stove species. SYN. 

 Diplazium melanocaulon. 



A. Michauxil (Michaux's).* eau. stout, sti. 4in. to Sin. long. 

 fronds 9in. to 24m. long, Sin. to 9in. broad, ovate-deltoid, bi- or 

 tripinnate ; pinnules oblong, deeply serrate, or cut quite to the 

 rachis. United States. A very handsome hardy species, closely 

 related to the Lady Fern, of which it may be only a variety. 



A. monanthomnm (one-flowered).* tti. densely tufted, Sin. to 

 6in. long, fronds 12in. to 18in. long, about lin. broad, with 

 twenty to forty horizontal, sessile, sub-dimidiate pinnae on each 

 side, which are about iin. long and Jin. deep, the upper side cre- 

 nate, suddenly narrowed at the base, the lower more or less dis- 

 tinctly cut away in a straight, or, in the lower pinnae, decurved 

 line, sori linear-oblong, usually one or two, parallel with the 

 lower edge of the pinnae. Temperate regions of both hemispheres. 

 Greenhouse species. 



Asplenium continued. 



A. montanum (mountain).* sti. tufted, 21n. to Sin. long, fronds 

 2in. to Sin. long, lin. broad, lanceolate-deltoid ; lowest pinnae dis- 

 tinctly stalked, deltoid, sharply serrated round the outer edge. 

 sori short, copious. United States, 1812. Frame or greenhouse 

 species. 



A. multisectum (much-cut). Synonymous with A. aspidioides. 



A. mussefolium (Musa-leaved). A variety of A. Nidus. 



A. myriophyllum (myriad-leaved). A variety of A. rhizo-

 midrib rounded on the back ; veins fine and parallel, about iin. 

 apart, sori reaching about half wav towards the margin. India, 

 &c., 1820. SYN. A. australasicum. See Fig. 172. 



A. N. australasicum (Australian). Midrib keeled on the 

 back, often black. Australia, &c. The two former are best 

 treated in the stove ; the latter thrives well in the greenhouse.
