LAPAGERIA 



must be open and sundy. They should be trained 

 atciiiust a wall, facing either the east or north. Abun- 

 dant syringing, temperature not to exceed 50° to 00° at 

 night, and even as low as 4,')° at night in winter, plenty 

 of air, -these are requisites. In winter they require but 

 little water except spraying when the temperature war- 

 rants it. Where no sueli sandy strata or subsoil exists 

 it must be provided, but care must be taken that they 

 are not crowded into an obscure corner where the soil 

 will not dry out, as otherwise it will sour and the plants 

 not do well. The roots nnist not be put too deep, as the 

 plant is a shallow rooter. If no sand-bed can be had it 

 is best to have the young plants in shallow pans, an<l. 

 breaking the bottom, set them into such a prepared 

 bed, sinking the pans until the roots go out "into the 

 prepared bed. In their native homes Lapagerias grow 

 where pleuty of water falls during their growing sca- 

 son and where tliey are semi-dormant the rest of the 

 year. They flower from the well-ripened an<l matured 

 wood of a strong growth. Propagation is effected by 



by means of layers or from seeds.

LAPEIEOtrSIA. Preferably spelled Lape!/roiisia . 



LAPEYROOSIA (Jean Franvois Galoup de Lapeyrouse, 

 distinguished French naval officer, born 1741). Irith)- 

 ceae. About 32 species of African bulbs, something like 

 Preesias, but with blue or red lis., which are produced in 

 summer instead of spring. They can be grown outdoors 

 in the North with some winter covering, and are saiil to 

 be quite hardy south of Washington, D. C, if planteil 

 deep. By American dealers they are still listed uniler 

 the name of Anomatheca, which Baker has reduced to 

 one of the 3 subgenera of Lapeyrousia, characterized by 

 having several Ivs. forming a 2-ranked basal rosette, ac- 

 companied by a long, Ijranched stem. Lapeyrousia is 

 furtlier distinguished from Freesia by having a more 

 slender perianth-tube, with the stamens inserted at tlie 

 throat instead of below; also by the ovules being more 

 regularly superposed instead of crowded together. The 

 species of Lapeyrousia have an egg-shaped or globose 

 corm about K in. thick, and matted with tunics : Ivs. 

 linear or sword-shaped: inflorescence various, often a 

 loose, 1-sided, more or less zigzag spike, as in Freesia: 

 rts. variously colored, 1-2 in. across; perianth tube long 

 or short; segments spreading, 'A larger than theother:!. 

 l\Ionographe(i by Baker in his "Hand book of tlie Iritira'." 

 and also in the African floras. 



These plants will probably never have anything like 

 the degree of popularity enjoyed byFreesias, becau-^e of 

 their later season of l>looni and lack of fragrance. Proli- 

 ably the most popular kind is L. crite}it(i, which grows 

 (i-10 in. high, blooming in summer and fall. In a shel- 

 tered and in light, porous soil it generally succeeds in 

 the North without any protection, but the bull)s ;ire 

 safer in very severe winters under a covering of litter 

 or straw. The bulbs increase rapidly, and should be di- 

 vided every few years before they become too crowded.

corymbdsa, Ker. ( Aunmatliecn corymbosa , Hort. A. 

 Blanc). This belongs to the subgenus Ovieda, having 

 usually 1-2 basal Ivs., while the next 3 species belong to 

 the subgenus Anomatheca, having more numerous Ivs. 

 L. corymbosa has 1 basal leaf which is spreading, sword- 

 shaped, 4-6 in. long: inflorescence a dense flat-toppeil 

 cluster of as many as 1.5 fls. each about 1 in. across, 

 with practically 'regular segments, blue, with a st:ir- 

 shaped white figure near the throat, outlined in bhick

LAKDIZABALA (after the Spanish naturalist Lardiz- 

 abal y Uribe). Jii-rberidiirea'. Six species of S. Ameri- 

 can shrubby climliers, mostly Chilean, one of which is 

 cult, outdoors in S. Calif, and the warmer parts of En- 

 rope. It is sonu-thing like the well known hanly vine 

 Akebio qiiiiiiila. having similar, odd-looking, dark-col- 

 ored fls., but the leaflets are in 3's instead of 5's. Tie- 

 leaves may be once, twice or thrice termite, aTid tl]e\ 

 are dark green, glossy, and here and there hav.^ 1 or 2 

 almost spin}' teeth. 



There are 4 genera <if the Barberry family contaiiiiiig 

 shrubby climbers that are cult. Of these Akeliia is the 

 iiest. Akebia ;i]id Hollioellia have free stamens : Lardiza- 

 bala and Stauntonia have monadelphous stamens. In 

 all of these the showy parts are the si-pals, the (; pet- 

 jds being much smaller in Lardizabala ami absent in 

 Stauntonia. Lardizabala is further distinguished from 

 Stamitonia by having once- to tlirice-ternate foliage and 

 oblong lierries. while Stauntonia has digitate foliage 

 with 3-7 leaflets.

LAEIX (ancient Latin name). Coniferir. Larih. 

 Tamarack. Ornamental deciduous <-oniferous trees oj 

 pyramidal habit, with the lvs. linear and clustered ex- 

 cept on yotnig sho(»ts, where they are sjdrally arranged, 

 and with the pistillate tls. often very conspicuous by 

 their bright purple color: cones erect, globose to ob- 

 long, rarely more than 2 in. long. They are all hardy 

 North except the Himalayan L. Griffithi. and are often 

 planted as park trees, chiefly for the light green foliage 

 and the regular conical, or in some vars. pendulous, 

 habit The most beautiful is probably L. Irptolepis, 

 with the foliage turning bright yellow in fall, wdiile the 

 others assume only a pale yellow color. They are also 

 very valuable forest trees, especially for the northern 

 and mountainous regions ; no forest tree goes farther 

 north than the Larch, reaching in N. America 07° and 

 in Siberia 72° of latitude. The wood is hard, heavy and 

 very duralile, and nmch used for construction, that of 

 L. oerideiitii lis being considered the best of all Anjeri- 

 can conifers. From the European Larch turpentine is 

 obtained. The bark contains tamiin, and an extract is 

 used for tanning leather. The Larch grows in almost 

 any kiml of soil, including clay and limestone, and in-e- 

 fers a somewhat moist, but well-drained soil and an 

 open situation; the American Larch grows well e\'en in 

 swamps. Cnfortunately several insects and fungi prey 

 on the Larch, and sometimes do considerable damage, 

 especially the leaf-eating larvae of some moths. Pro)>.
