LAYIA 



LATIA (Thomas Lay, naturalist in the Beechey voy- 

 age). Cotnpdsittp. About V.i species of California an- 

 nuals, with yellow or white fls. in spring or early sum- 

 mer. Lvs. chietly alternate, all eutire or some, particu- 

 larly the lower, with about 2 pairs of linear side lobes 

 above the middle of the leaf. For general culture they 

 .■ire probably inferior to Madia elegant, which has a simi- 

 lar habit and is distinguished by the blood-colored spot 

 at the base of the rays. The lis. in Layia are about 1-lK 

 in. across, and the rays are distinrtlv :Moothed. The 

 species described below are ditTiisr, mui-b-branched and 

 about a foot high. It is prohat-b- tlint fi»r best results 

 they should be started early indoors, and transplanted 

 outdoors in May. Easy to grow.

isb, its copious villous hairs much shorter thantheawn- 

 shaped bristles, which are long plumose below the mid- 

 dle. This and the next have a few small, scattered, 

 stalked glands which are wanting from the last 

 two. Gn. 31, p. 465. — Procurable from western 

 collectors. Perhaps the best of the genus.

 are upwardly scabrous. B.M. 3719. — Cult, in Eu.

 pubescent. 



Calli^Ussa, Gray. Akenes villous-pubescent or 

 partly glabrate: pappus of 10-18 very unequal 

 and rigiii awl-shaped awns. B. R. 22:1850 (er- 

 roneously as ilj-yura clirysanthimoides). 



chryBanthemoldes, Gray {Oxyura chrysanthe- 

 violdes, DC). Akenes wholly glabrous, broader: 

 pappus none. Not B.R. 22:1850, which is the 

 above. According to Thorburn this is a hardy 

 annual trailer with white fls., blooming in sum- 

 mer and autumn.

LEBIDIEROPSIS (Greek; resembling Lebidiera, a 

 genus now inc-luded in Cleistanthus). Enphorhi&cece. 

 This genus includes a small tree with very hard wood, 

 and of unknown value, introduced from a botanical gar- 

 den of northern India by Reasoner Bros., Oneco, Fla. 

 Lebidieropsis was reduced by Benth.im and Hooker to 

 the rank of a subgenus of Cleistanthus, but in the 

 Flora of British India Hooker says that Lebidieropsis 

 should probably be restored, the se^ds being globose, 

 while in Cleistanthus they are always oblong. The seeds 

 also differ in structure. Generic characters of Cleistan- 

 thus are: trees or shrubs: lvs. alternate, 2-ranked, en- 

 tire: fls. small or minute, in axillary clusters and spikes, 

 monoecious; calyx 5 cleft or 4-6-cleft; petals as many, 

 minute; stamens 5; filaments united in a column in the 

 center of the disk: ovary 3-celled. 



OTbicul&ris, Muell., Arg. Lvs. \M-A in. long, lH-3 in. 

 wide, leathery, broadly obovate or elliptic, tip rounded 

 or retu.se, glaucous beneath, nerves 5-8 pairs: fls. silky, 

 .3-6 in a cluster; petals fleshy, narrow: seeds 2 lines 

 thick, chestnut-brown, with scanty albumen. Hooker 

 does not recognize the 3 varieties distinguished by 

 Mueller on the shape and hairiness of the lvs. 



LfiDUM (ledon, ancient Greek name of Cistus). 

 Ericacea'. Labrador Tea. Ornamental low evergreen 

 shrubs with alternate, entire, short-petioled lvs., slightly 

 fragrant when bruised, and with handsome white fls. in 

 terminal umbels, appearing in early summer. They are 

 all hardy North, and well adapted for borders of ever- 

 green shrubberies or for planting in swampy situations. 

 They thrive as well in sunny as in partly shaded situa- 

 tions, and prefer a moist, sandy and peaty soil. Trans- 

 planting is easy, if the plants are moved with a sufRcient 

 ball of earth. Prop, by seeds sown in spring in sandy
