LITTONIA (Dr. Samuel Litton, professor of botany 

 in Koyal Dublin Society). Lili&cett. Littonia and 

 Gloriosa are caUed Climbing Lilies. They are tender, 

 tuberous plants, with glossy, lanceolate Ivs. which curl 

 at the tips into tendrils, enabling the plants to reach 

 C-8 ft. The fls. are 6-parted, but in Littonia the seg- 

 ments are not refiexed like a Cyclamen, as in Gloriosa. 

 Fls. nodding, bell-shaped, orange, 1 in. or more across; 

 segments oblong, acuminate, IM in. long: capsule long, 

 3-celled; seeds scarlet, about the size of a sweet pea, 

 round, arranged in 2 series. The odd-shaped tubers are 

 about 1 J^ in. across and may be planted outdoors in May . 

 There are 4 species, 1 from Arabia, 1 from S. Africa 

 and 2 from tropical Africa. 



mod^sta, Hook. Lower Ivs. in 3's, upper ones alter- 

 nate : perianth segments provided with a small oblong 

 nectary, partially closed by a ciliated scale on each side : 

 style 3'-cut. S. Africa. B.M. 4723. Var. Keitii, Hort., is 

 an improved form, with larger and more abundant fls.

LIVERLEAF. Bepafica. 



LIVERWOKT. A general name for a group of cryp- 

 togamia (flowerless plants), somewhat allied to mosses 

 and known as Hepaticfe. Conocephalus and Marchantia 

 have been offered by dealers in native plants as suitable 

 for rockwork and bog gardens. Lunularia is a common 

 weed in greenhouses.

LIVISTdNA (Patrick Murray, Baron of Livistone). 

 Pabinlcete. About 14 species of fan palms from tropical 

 eastern Asia, Malaya and Australia. Trunks usually 

 tall, stout, ringed below, clothed above with dead leaf- 

 sheaths: Ivs. spreading, orbicular, plicate, split to the 

 middle or below; the segments bifid, infolded, naked or 

 fibrous along the margins ; rachis 

 short; ligule small, cordate, free; pe- 

 tiole long, stout, flat or rounded above, 

 convex below, often spiny along the 

 margins; sheaths margined with re- 

 ticulate fibers : spadices long, at first 

 ascending, pendent in fruit, long- 

 peduncled, loosely branched, the 

 branches slender: spathes many, long, 

 tubular, compressed, sheathing the 

 peduncle, thick, coriaceous, bifid or 

 21ipped, 2-keeled or ancipital : no 

 bracts or bractlets: fls. greenish: fr. 

 smooth and shining, oblong-globose or 

 ellipsoidal, black, blue, yellow or 

 brown. 



From the seven allied genera men- 

 tioned under Licuala, Livistona is dis- 

 tinguished by the following charac- 

 ters: fls. hermaphrodite: carpels of 

 the ovary globose, distinct or slightjy 

 cohering : styles short, distinct or co- 

 hering: albumen not twisted, broadly 

 scooped out on the ventral side: 

 branches of the spadices not bracted 

 or the lower ones bracted.

 B. Petioles u'ithout spines.

 IS in. wide, split into very narrow acuminate lobes, the 

 lower ones free almost to the base, the inner ones split
