LIME 



LIMNOCHARIS 



Limes may be grown as seedlings or they may be 

 propagated by budding on sour orange or rough lemon 

 seedlings. 



In orchard plantings, the seedlings are set 12 to 15 

 feet apart each way and the budded trees about 20 

 feet. The cultivation, fertilizing and general care are 

 the same as for other citrous fruits. 



The fruit is gathered when full grown, but while 

 still green, packed and shipped immediately. Care- 

 fully handled, they keep well, but do not usually stand 

 up so long as processed or cured lemons. It is some- 

 times stated that the Tahiti lime is a poor keeper. 

 This is often due to the attacks of fungous diseases 

 which can be guarded against. 



They are attacked by the ordinary citrous insects. 

 Anthracnose or wither-tip is the most serious fungous 

 pest. This destroys the smaller twigs and branches 

 and produces hard wart-like spots on the Mexican 

 lime fruit. It may be held in check by careful pruning 

 out of dead and diseased wood and by spraying with 

 bordeaux mixture. H. HAROLD HUME.

citrous fruit was originated by the writer in 1909 by 

 crossing the common West Indian lime with the kum- 

 quat. While the lime is the tenderest of all commonly 

 grown citrous fruits and is frequently frozen to the 

 ground even in southern Florida, the kumquat, because 

 of its remarkable winter dormancy, is one of the har- 

 diest of the evergreen citrous fruit trees. The limequat 

 possesses in large measure the cold-resistance of the 

 kumquat and can be grown in regions too cold for the 

 lime. The limequat also shows resistance to citrus 

 canker, a destructive bacterial disease, caused by 

 Pseudomonas citri. Limequats vary in size, some 

 being no larger than a large kumquat, while others 

 are the size of a lime. The skin is thin and has an 

 agreeable aroma and flavor; the pulp is juicy and 

 pleasantly acid. This hybrid, which fruited for the 

 first time in 1912, is a vigorous grower and a heavy 

 bearer. It is being tested in the South.

LIMNANTHEMUM: Nymphoides. 



LIMNANTHES (Greek, marsh flower}. Limnan- 

 thdcese. A few species of American annuals growing near 

 the water. Low, diffuse, rather fleshy: Ivs. pinnately 

 dissected: fls. white, yellow or rosy, solitary on axillary 

 peduncles, regular, the parts in 4's-6's; sepals valvate 

 in the bud; glands alternating with the petals; stamens 

 usually 10: carpels distinct or nearly so, at first fleshy, 

 at length hard and wrinkled, indehiscent, separating 

 from the short axis; ovule solitary. By some authors 

 this genus is kept in Geraniacege, but this and Floerkea 

 are by others separated in a small family Limnanthacese. 

 The two genera are sometimes combined, but Floerkea 

 is 3-merous and Limnanthes is commonly 5-merous, 

 and there are other differences. 



Douglasii, R. Br. (Floerkea Douglasii, Baill.). 

 MEADOW FOAM. Spreading, branched and glabrous 

 yellow-green low herb with handsome white-yellow fra- 

 grant fls. nearly 1 in. across, cult, as a garden annual: 

 about 1 ft. high: Ivs. pinnate; Ifts. sharply lobed or 

 parted: petals oblong-spatulate, notched at apex, more 

 or less yellow, white toward the tip : fr. smooth or slightly 

 corrugated. Calif., Ore. B.M. 3554. B.R. 1673. Gn. 

 72, p. 611. G. 4:3. The fls. vary somewhat in color: 

 usually the petals are white with yellow toward the 

 base; sometimes roseate and yellow. L. grandiflbra (fls. 

 larger) and L. sulphhrea are garden names. The plant 

 is easy of cult. L. H. B. 



LIMNOBIUM (living in pools, from the Greek). 

 Hydrocharitacese. American aquatic herbs, one of 

 which is in the trade. 



Stemless plants, spreading by means of runners, 

 the large Ivs. floating: monoacious, the fls. arising 

 from spathes borne on the rootstock, the pistillate 

 single from a spathe and the staminate 2-4 from a 

 spathe, all with 6 white segms. or petals, the inner ones 

 being very narrow; stamens in a column, bearing 

 anthers at unequal heights; ovary with several (6-9) 

 locules and as many stigmas, ripening into a many- 

 seeded berry. As defined by some writers, the genus 

 comprises a single species, L. Spongia; others unite 

 with it the direcious Hydromystria (incl. Trianea), 

 2 or 3 species of Trop. Amer. 



Spongia, Rich. (Hydrocharis Spdngia, Bosc. L. 

 Bdsci, Rich.). AMERICAN FROGBIT or FROG'S-BIT (the 

 European Frogbit is Hydrocharis) . A neat floating plant, 

 with purplish, hanging, hairy roots and long-stemmed, 

 orbicular, cordate or ovate Ivs. 1-2 in. long and pur- 

 plish beneath. Lake Ontario to Fla. and Texas. Good 

 for the aquarium. According to William Tricker, its 

 mottled foliage and silky rootlets are very attractive 

 and make it valuable in small areas or tanks, but when 

 grown out-of-doors in summer in tubs or pools, it is 

 very vigorous and soon becomes crowded; the Ivs. 

 instead of floating, then appear in an erect state, the 

 spongy condition of floating Ivs. haying disappeared; 

 it is really a floating plant, prop, by division of runners, 

 and should not be placed in shallow water, where it can 

 readily root into the soil. 



L. stolonlferum, Griseb. (Hydromystria stolonifera, Mey. 

 Trianea bogotensis, Karst.), is more sturdy in habit, of a lighter 

 color especially in winterdoes not make such long runners, and 

 forms more compact and attractive rosettes of Ivs. Mex. to Para- 

 guay; Trinidad. L J JJ 



LIMNOCHARIS (from Greek, referring to marsh 

 habitat) . Butomdcese. Water plants, suitable for aquaria 

 and for plunging in pools in summer. 



Perennial aquatic herbs, stoloniferous, with lanceolate 

 or ovate, petiolate, emersed Ivs.: fls. perfect; sepals 3, 

 persistent; petals 3, thin, fugacious; stamens numer- 

 ous, the outer ones sterile: carpels 15-20, ver titillate, 

 style none, stigma sessile and extrorse. Two species 

 are admitted by Buchenau, (Engler's Pflanzenreich, 

 hft. 16. 1903), both tropical American. From Hydroc-
