 LITHOSPfiRMUM (Greek, rock seed; the seeds like 

 little stones). Borraginttcece. This includes a few low- 

 growing hardy herbaceous perennials of minor impor- 

 tance. The best known is L. 

 prostratum, a rock-garden 

 trailer, which bears numer- 

 ous leafy spikes of blue fls., 

 each about % in. across, from 

 early summer 



in native plants. Seeds of the Gromwell and the western 

 species are procurable, and plants of the otlicr kinds.

 shrub: Ivs. lanceolate-linear, margin somewhat revolute: 

 tube of corolla pubescent outside, densely villous at 

 apex. S. Eu. This is presumably the plant in the trade, 

 since i. prostratum, Buckl., is a white-fld. annual 

 properly called i. Matamorense. However, i. prostra- 

 tum, Lois., is referred by Index Kewensis to L. fruti- 

 COSH/H, which see. Gn. 45, p. 135. J. H. III. 32:475.

 ralized from Eu.

 Apparently all .iiailt - Pitween early large fls. and late 

 small onei. I'rauiis. D. M. Andrews says it has pale 

 cream fls. Var. longUldrum {L. longiflorum, Hort., D. M.

LITHB.ffiA ( Chilean name ) . Anacardi&cea:. A genus 

 of small South American trees related to Rhus, and by 

 Bentham and Hooker included in that genus. The plant 

 cult, by some under this name seems not to be true to 

 name, as it is a tree with undivided Ivs., while the true 

 plant is as hrub with 1-3 pairs of Ifts. and odd pinnate.
