LYCOPEKSICUM 



LYC'Ol'oniUM 



2234. The currant tomato, Lycopersicum 

 pimpinelliiolium. 



Var. grandifolium, Bailey. Large- 

 :23'2. Lvs. very large, 

 I)!ane, the 1ft s. few (about 2 pairs) and larj;e, 

 with margins entire or very nearly so, aiui 

 secondary Ifts. usually none. — Of seedling 

 origin about 45 years ago. The Mikado 

 and Potato Leaf are characteristic varieties 

 of this. In very young plants, the lvs. 

 are usually entire. Thi.s race has producetl crosses of 

 commercial value with var. rulgare. In P'ig. 2232, No, 2 

 i.s a If. of var. vulgare, No. 1 is var. grandifolium, and 

 No. 3 is a If. of a hand-made cross between the two. 



pimpinellifdlium, Dunal (L. racemlgcrum and L. 

 Tocemijorme, Langc. Holanum racemijidruin, Vilin., not 

 Dunal). Currant ToM.\To. Fig. 22:54. Plant weaker, 

 vf?n,- diffu.se and twiggj-, scarcely pubescent: lvs. with 

 .small ovate nearly entire Ifts,, and very small second- 

 ary Ifts.: racemes elongating, distichous, bearing 10-40 

 small currant-like red berries. S. .'Vrner. — Grown a.s a- 

 curiosity and for ornament. The plant makes an excel- 

 lent summer cover for brush f)r rubbish piles. The frs. 

 are edible, but are too small for domestic use. However, 

 it ha.s been intro. a'i a garden vegc^table under the name 

 of German Raisin tomato. It hybridizes with L. 

 esculenlum (sec Kig. 2235). I^, H. IJ. 



LYCOPODITJM (Greek, violf-fool) . Lymimdiiiccie. 

 Club-mos.s. Groi.'.sd-pi.ne. Rinmng-pine. .V group 

 of pteridophytes, with erect or trailing stems, commonly 

 used for holiday decorations. 



Leaves narrow, needle- or scale-like, arranged in 4 to 

 many ranks, anrl bearing spores in sporangia, located 

 either in the axils of ordinary lvs. or in the axils of 

 modified lvs. clustered in spikes.— About lOf) species 



are known. The spores of some species form the 

 officinal lycopodiuin powder. Tlic |)lants which 

 llorists grow as lycopodiuuis are sclagiuelhis. Ilovti- 

 cullurally, the spt'cies of Lycopodiuni are valuable 

 mainly as oddities. The hardy species are not always 

 easy to get started, and the tender species need 

 special cult , for good results. See Selaginella. 



A. Lrs. many-ranked. 

 11. Sporangia in the axils of unaltered lvs. 



Selago, Linn. Sts. erect, 3-9 in. long, dichoto- 

 mcnisly branched: lvs. ascending, hollow at base, 

 glossy green, not reflexed. Northern hemisphere, 

 usually in high altitudes, 



lucidulum, Miclix. (Fig, 2236), much like preced- 

 ing, but usually larger, is more connnon in lowlands, 

 antl has lvs, wi<le in the middle and erose, 



squarrosum, Forst. Sts. pendulous, 1-2 ft. long, 2-3 

 times di<-hotomously branched: lvs. firm, dark green, 

 spreading, '2-'4'"- 1<>"k: sporangia in the axils of re- 

 duced lvs., forming a spike, K, Indies. 



BB. Sporangia aggregated in terminal spikes, 

 c. Sts. pcndidous: lvs. acute. 



Phlegmaria, Linn. Sts, 3/2-2 ft. long, dichotomously 

 forked: lvs. ,'2-M in. long, ovate: spikes copious, lax, 

 3-t) in, or more long. Tropics of Old World. 



cc. Sts. erect, tree form. 

 cemuum, Linn, Sts, erect, reaching 3-4 ft,, copiously 

 branched: lvs. crowded, linear: spike-s sessile, }4'^i™- 

 long, curved downward. Tropics of both hemispheres, 

 occasionally in our Gulf states. 



2235. Lycopersicum esculentum beneath; L, pimpineUifotium 

 at top; hybrid between.
