THE DICTIONARY OF GARDENING, 



Lycopodinm continued. 



slender, upright stems, Sin. to 4in. high. New Zealand. A rare 

 and handsome, terrestrial, greenhouse species. 



L. Selago (Selago). Fir Club Moss. Stems erect, Sin. to 4in. high, 

 forked. Branches level at the top. I. in eight rows, uniform,

 green, acuminate leaves, about iin. long. h. 9in. to 12in. 

 Jamaica. A very handsome stove species ; the ends of its 

 branches are swollen, and the sporangia situated at the base of

 pretty greenhouse species, thriving well in peat and sand, and 

 with plenty of drainage.

 whorls round the stem, iin. long, acuminate, dark green. 

 Mauritius. A very handsome, procumbent, stove species, grow- 

 ing from lOin. to 20in. long. 



LYCORIS (named after a beautiful Roman actress, 

 mistress of Marc Antony). OBD. AmaryllidecB. A genus 

 comprising three species of greenhouse bulbous plants, 

 natives of China, Japan, and Central Asia, allied to 

 Amaryllis, from which they may be distinguished by 

 the undulated divisions of the spreading perianth being 

 curved upwards, and bearing a simple fringed stigma. 

 For culture, &c., see Amaryllis. 



L. aurea (golden).* /. golden-yellow, stalked, erect, funnel- 

 shaped, clavate ; segments linear-lanceolate. August and Septem- 

 ber. I. greenish, strap-shaped, h. 1ft. China, 1777. A very 

 pretty species, the flowers appearing before the leaves. SYN. 

 Amaryllis aurea (under which name it is figured in B. M. 409). 



L. radiata (rayed), fl. deep pink, approaching to scarlet. June. 

 I. linear-ligulate, obtuse, glaucous-green, about iin. wide. h. IJft. 

 China, 1758. SYN. Nerine japonica. (B. R. 596 ; A. B. R. 95, 

 under name of Amaryllis radiata.) 



Lyda continued. 



FIG. 492. LYCORIS SEWERZOWI, showing Habit, and detached 

 Flower (natural size). 



L. Sewerzowi (Sewerzow's).* fl. brownish-red, fragrant. Sum- 

 mer. I. strap-shaped, bluntish. h. 1ft. Turkestan 1877 See 

 Fig. 492. (R. G. 914.) 



LYDA. A genus of Sawflies, the larvae of which do 

 considerable damage to trees. The larvas have no pro- 

 legs, but at the end of the body are two organs some- 

 what like true legs, and with the help of these organs 

 they move along slowly. They are usually semi-social, 

 spinning a web in common over twigs and leaves, but 

 also each spinning a separate tube for itself within the 

 web, in which it lives. They become pupae in the soil. 

 L. nemoralis and L. Pyri injure Plums and other stone- 

 fruit trees, Apple and Pear-trees, &c., and they also eat 

 Hawthorn ; other species feed on Willows, Birches, and 

 Alder, and several (L. campestris, L. erythrocephala, &c.) 

 do very considerable injury to conifers. The habits of 

 the larvae facilitate their destruction in the webs, the 

 appearance of which is shown at Fig. 493.

LYCEUM (from lygeo, to bend; alluding to the flexi- 

 bility of the plant). OED. Graminece. The only species 

 of this genus is a hardy perennial grass. It thrives in 

 any light loamy soil, and may be increased by dividing 

 at the roots. 



L. Spartum (Spartum). fl. hermaphrodite ; peduncle terminal ; 

 spikelet usually large, erect or nodding, two, rarely three- 

 flowered. May. I. rush-like, erect, long, convolute-terete, subu- 

 late, acuminate, h. lift. Mediterranean region (rocky places 

 on the seashore), 1776. This species furnishes Albardine, a 

 valuable material for paper-making. The plant which yields the 

 Esparto of the paper-makers is Macrochloa tenacissima. 

 LYG-ODICTYON FORSTERI. A synonym of 

 Lygodium reticnlatnm (which see). 



LYGODICTYON HETERODOXUM. A synonym 

 of Lyg-odium heterodoxnm (which see). 



LYGODICTYON LINDENI. A synonym of 

 Lygodium heterodozum (which see). 



LYGODIUM (from lygodes, flexible ; referring to the 

 flexible habit). OBD. Filices. A genus comprising about 

 eighteen species of handsome, wide-scandent, twining, mostly 

 stove ferns, widely diffused. Capsules solitary (or casu- 

 ally in pairs), in the axils of large, imbricated, clasping 

 involucres, which form spikes either in separate pinnae 

 or in lax rows along the edge of the leafy ones. The 

 species are readily distinguishable from all others by 

 their wide-scandent climbing stems ; the fronds are per- 

 manent, and become interlaced with each other, some- 

 times forming, together with other plants, impervious 

 thickets. As a rule, the species thrive in a compost of 

 peat, loam, and sand, in equal parts. For general cul- 

 ture, see Ferns. 



L. artionlatum (jointed), primary petiole Jin. to iin. long; 

 secondary Iin. or more long ; barren pinnules twice forked, each 

 bearing four ligulate-oblong segments, which are 2in. to 3in. 

 , about iin. broad, blunt at 



the point, very distinctly artic 



long, 



lated at the base on a short petiole ; fertile pinnules many times 

 dichotomous, the short spike in dense clusters, which are often 

 almost destitute of lamina. New Zealand, 1844. 



L. circinatum (circiuate). A synonym of L. dichotomum. 



L. dichotomum (dichotomous).* primary petiole so much re- 

 duced that the fork seems almost to spring from the main raehis ; 

 secondary Iin. to 2in. long, firm, naked ; pinnules digitate, with 

 five or six lobes reaching nearly down to the base, or once or 

 even twice forked; ultimate barren divisions 4in. to 8in., or even 

 12in. long, iin. to jin. broad, the fertile ones contracted, spikes 

 one to two lines long, in close marginal rows. Chusan, Hong 

 Kong, &c. SY.NS. L. circinatum and L. pedatum. 



L. Forstert (Forster's). A synonym of L. reticulatum. 



Iu hastatum (halbert-shaped). A synonym of L. volubile.
