LIME 



LIMNOCHARIS 



Limos may bo grown ju; stHnllings or they may be 

 pnn>asate<l by budding on sour orange or rough lemon 



In orchani i)lanlinRS,.tho seedlings are set 12 to If) 

 feet apart eaeh \va>- aiid tlie budded ti-ees about 20 

 fe*t. The eultivatioii. fertilizing and general care are 

 the same :us for other citrous fruits. 



The fruit is gathered when full grown, but while 

 still green, packed and shiiipcd immediately. Cmv- 

 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 C!Ui be guarded against. 



They iire attacked by the ordinary citrous insects. 

 Anthraenose or wither-tip is the most .serious fungous 

 pt>st. This destroys the smaller twigs and branches 

 and pro<luees hard wart-like sjHits on the Mexican 

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

 out of dead and diseased wood and by sijraying with 

 bordeaux mixture. H. II.vrold Hume. 



LIMEQUAT (from lime and [kum] quat). Fig. 

 217G. Hybriils between the common lime {Citrus 

 auranlifofia) and the oval or roim<l kumquats (For- 

 tunella margarita. F.japonica). This new and promising

cross-section, of an oval limequat. ( X l-ii 



citrous fruit was originated by the writer in 1909 by 

 crossing the common WY'st Indian lime with the kum- 

 quat. While the lime is the tenderest of all commonly 

 grown citrous fruits and is frefiuently 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 tre('s. The limequat 

 p>ssesses in large measure the cold-resistance of the 

 kumquat and can be grown in regions too col<l for th(! 

 lime. The limequat al.so shows resistance to citrus 

 canker, a destructive bacterial disease, caused by 

 FuewlomoTuu citri. Limequats vary in .size, some 

 being no larger than a large kumquat, while others 

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

 agreeable aroma and flavor; the pul[) is juicy an<l 

 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 : Xi/miiltoiiles. 



LIMNANTHES (Cireek, marxh _flowir). Limiian- 

 tli(ici;i . \ few species of American annuals growing near 

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

 dis.sectcd: lis. white, yellow or ro.sy, solitary on axillary 

 peduncles, regular, the parts in t's-ti's; seiials valvate 

 in the bud; glands alternating with the petals; stamens 

 \isually 10: carpels distinct or nearly so, at first fleshy, 

 at length hard and wrinkled, indehisccnt, .separating 

 from the short axis; ovule solitary. By .some authors 

 this genus is kept in ('.craniacea\ but this and Floerkea 

 arc by others separated in a small family Limnanthacea?. 

 The two genera are sometimes combined, but Floerkea 

 is :5-merous anti Limnanthes is commonly 5-merous, 

 and there are other dilTerences. 



Doiiglasii, R. Br. (Floerkea Douylasii, Baill.). 

 IMi:.\Dow F().\M. Spreading, branche<l and glabrous 

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

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

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

 parted: jjetals 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. On. 

 72, p. (ill. 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. svlphiirea are garden names. The plant 

 is easy of cult. L. H. B. 



LIMNOBIUM (living in pools, from the Greek). 

 HtjdrdchariUicrse. American aquatic herbs, one of 

 which is in the trade. 



Stemless plants, spreading by means of runners, 

 the large Ivs. floating: mona?cious, the fls. arising 

 from spathes borne on the rootstock, the pistillate 

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

 si)athe, all with white .segms. or petals, the inner ones 

 being very narrow; stamens in a colunm, 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 diu'cious Hydromystria (incl. Trianea), 

 2 or 3 species of Trojj. Amer. 



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

 BSsci, Rich.). Amekican Frogbit or Frog's-bit (the 

 European Frogbit is Hydrocharis) . A neat floating plant, 

 with pur|)lish, 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 

 lor 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. having disappeared; 

 it is really a floating plant, jirop. by division of runners, 

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

 readily root into the soil. 



L. stoloni/cTum, Griseb. (Hydromystria stolonifcra, Mey. 

 Trianea boKotonais, Karst.), is mure sturdy in habit, of a lighter 

 color — especially in winter — does not make such long runners, and 

 forms more compaet and attractive rosettes of Ivs. Mex. to Para, 

 guay: Trinidad. L H. B. 



LIMNOCHARIS (from Greek, referring to marsh 

 habitat). liiitomnccx. Water plants, .suitable for aquaria 

 and for i)lunging in pools in simimer. 



Perennial aquatic herbs, stoloniferous, with lanceolate 

 or ovate, petiolate, emers(«l Ivs.: fls. perfect; sepals 3, 

 I)ersistent; petals 3, thin, fugacious; stamens numer- 

 ous, the outer ones sterile: carpels 15-20, verticillate, 

 style none, stigma sessile and extrorse.— Two species 

 are admitted by Buchenau, (Engler's Pflanzenreich, 

 hft. 16. 1903), both tropical American. I'rom Hydroc-
