SANTALACEÆ

_Sandalwood Family_

Low herbs parasitic on the roots of other plants, with entire leaves

and perfect, greenish flowers, either terminal or axillary; calyx

3—6-lobed; petals wanting; stamens as many as the calyx lobes and

inserted near their bases or opposite them upon the disc; fruit in

the only genus represented in the region, drupe-like, crowned by the

persistent style.

[Sidenote: =Comandra pallida= DC. _Pale Comandra._]

Stem slender and leafy, 6—12 inches tall, pale and glaucous. Leaves

linear or linear-lanceolate, acute or the lowest of those of the stem,

oblong-elliptic. Flowers small, less than ¼ of an inch high with short

pedicels, clustered at the summit of the stems, calyx purplish or

sometimes nearly white; fruit ovoid-oblong, nearly half an inch high

and crowned by the very short upper portion of the calyx tube.

On dry hillsides throughout the Rockies; flowering during June.

[Sidenote: =Comandra livida= Rich. _Northern Comandra._]

Stem slender, usually quite simple, 4—12 inches high. Leaves

thin, oval, obtuse or rounded at the apex, narrowed at the base,

short-petioled ½—1½ inches long, nearly half as broad, yellowish or

purplish-green when young, becoming bright green or often variegated

with age. Flowers small, less than ¼ of an inch broad; purplish-green,

in axillary clusters of 1—5 flowers; drupe globose-oblong, ¼ of an inch

in diameter, bright red when ripe.

Throughout the Rockies in moist ground and shaded mossy places and

borders of woods, flowering in June. While inconspicuous early in the

season, in midsummer it is apt to be quite showy on account of the

striking, golden yellow veining of the otherwise green leaves; this

condition is due to a fungoid or other disease of the plant.
