LAGETTA 



LAMIUM 



glabrous: Ivs. alternate, broad-ovate, pointed, 3-5 in. 

 long, evergreen: fls. small, white, in terminal racemes 

 or open lax bractless spikes; calyx tubular-cylindrical, 

 4-toothed; corolla 0; stamens 8; ovary ovoid, with a 

 single style and broad stigma: fr. small, globose, inclosed 

 in the persistent base of the calyx-tube. B.M. 4502. 

 J.F. 1 : 19. The lace-bark of New Zeal, is a very differ- 

 ent plant, Hoheria popidnea and also Gaya Lyallii 

 (Malvaceae). L. H. B. 



LAGUNARIA (named for its resemblance to Laguna3a, 

 which is now considered a section of Hibiscus and com- 

 memorates a Spanish botanist, Andres de Laguna,1494 

 or 1499-1560, physician to Pope Julius III). Malvacese. 

 An Australian (or Norfolk Island) tree cult, outdoors in 

 S. Calif, and indoors in Eu. It has large pale rose fls. 

 like Hibiscus, 2}^ in. across, with 5 spreading lobes, a 

 column of stamens and a 5-lobed shield-shaped stigma. 

 It differs from Hibiscus in having only 3, 4 or 5 decidu- 

 ous bract/lets, while Hibiscus usually has 5 or more. 

 Lvs. entire: fls. axillary; calyx 5-toothed; ovary 5- 

 celled. Species probably only. 1. 



Patersonii, Don. Scurfy-pubescent on young parts 

 and infl.: Ivs. oblong or broad-lanceolate or sometimes 

 ovate-oblong, 3-4 in. long, white beneath when young: 

 pedicels very short: bractlets at base of fl. 3-5, very 

 obtuse and united; calyx about M m - long; petals 

 narrow, \]/2 in. or more long, somewhat tomentose 

 outside. The Norfolk Isl. form (B.M. 769, as Lagunsea 

 Patersonia) is more scaly-tomentose, Ivs. broader, and 

 bracts earlier deciduous. They may be different species 

 or botanical varieties. The tree cult, in Calif, attains 

 a height of 50 ft., making a regular pyramidal head 

 and having a fine display of fls.; said to be well adapted 

 to street planting. L. jj. B. 



LAGURUS (Greek, logos, a hare; oura, a tail). 

 Graminese. HARE'S-TAIL GRASS. A hardy annual: 

 spikelets 1-fld., aggregated in a close panicle forming an 

 ovoid head; scarious glumes persistent and clothed with 

 fine woolly hairs: lemma with a dorsal awn. Contains 

 a single species, native of the Medit. region, cult, for 

 ornament, the small white heads being used for dry 

 bouquets. Seeds may be sown in fall and plants set 

 out in spring.

LALLEMANTIA (J. 

 L. E. Av6 Lallemant, 

 botanist of St. Peters- 

 burg). LaMatas. Annual 

 or biennial herbs, of or- 

 namental value for the 

 flower-garden. 



From Dracocephalum 

 the genus differs in the 

 character of the upper 

 lip, in which the lateral 

 lobes are on the face of 

 the middle lobe: gla- 

 brous or canescent: TVS. 

 opposite, dentate, the 

 upper ones passing into 

 narrow sessile floral 

 bracts: fls. small, blue; 

 calyx tubular, 15-nerved, 

 straight, 5-toothed; co-

what exserted, the throat widening; corolla-limb 2- 

 lipped; stamens 4, didynamous; style 2-lobed: nutlets 

 ovoid. Species 4, Asia. L. canescens, Fisch. & Mey. 

 (Dracocephalum canescens, Linn.), is annual or bien- 

 nial, 18 in.: Ivs. narrow, long-petioled, the floral Ivs. 

 sessile: fls. blue, in whorls, with oblong ciliate bracts; 

 corolla-tube exceeding calyx. 

 Asia Minor, Persia. Variable; 

 one form (var. dlbida, Voss) 

 being white. July, Aug.

LAMARCKIA (J. B. Lam- 

 arck, 1744-1829, distinguished 

 French naturalist, author of 

 the Lamarckian philosophy of 

 organic evolution). Graminese. 

 An ornamental annual grass, 

 often cult, under the name of 

 Chrysurus cynosuroides and C. 

 aureus. Spikelets of two kinds, 

 the fertile 1-fld., long-awned, 

 surrounded by the long sterile 

 spikelets of many obtuse 

 glumes, arranged in a 1-sided 

 crowded panicle. Contains a 

 single species, native from 

 Medit. region to Afghanistan, 

 intro. in Calif. Seeds may be 

 sown in the spring, or better in 

 the fall, and plants set out in 

 the spring. L. atlrea, Moench. 

 (Achyrbdes aurea, Kuntze).

LAMIUM (Greek for throat, referring to the shape of 

 the corolla). Labiatse. DEAD NETTLE. Annual and 

 perennial herbs of the Old World, of which several 

 run wild in this country as weeds and others are culti- 

 vated as hardy border plants. 



Botanically, Lamium is distinguished by a 2-lipped 

 corolla, of which the tube is somewhat longer than the 

 calyx, the upper lip ascending and concave, and the 

 lower one 3-lobed: stamens 4, in 2 pairs, ascending 

 under the upper lip: fls. in axillary or terminal whorls, 

 often rather showy: Ivs. opposite, mostly crenate- 

 dentate and petiolate: calyx awl-toothed. Low herbs, 

 of some 40 species in Eu., N. Afr. and Asia. 



Lamiums are diffuse mostly pubescent or hairy herbs, 

 commonly decumbent at the base and often almost trail- 

 ing. They are of the easiest culture in any open soil. 

 Useful for rockwork. The cultivated kinds are peren- 

 nial, and are commonly propagated by division. 



maculatum, Linn. (L. album and L. purpureum, Hort., 

 not Linn. L. variegatum, Hort.). Straggling or half- 

 trailing perennial, the tips ascending, slightly hairy: Ivs. 

 long-petioled (except the uppermost), cordate-ovate, 

 blunt, round-toothed: fls. 1 in. long, ascending in the 

 clusters, the upper lip strongly arched or hooded, the 

 tube 2-3 times longer than the calyx, hairy within. Eu. 

 Fls. usually purple-red, but sometimes varying to 

 white (when it is known as L. album, but the L. album 

 of botanists is a different plant, having pointed and 

 sharp-toothed Ivs.). The Ivs. are usually whitish 

 blotched along the midrib (var. variegatum), and in 

 this form it is common about old gardens, trailing in 

 the waste places. The plant is also run wild. L. 

 purpureum of the botanists is annual (see suppl. list 

 below). 



eriocephalum, Benth. St. much branched, glabrous: 

 lower Ivs. long-stalked, puberulent, small, orbicular,
