Heuchera caespitosa n. sp. Plate lvii. 



Ccespitose, from stout rootstocks covered with dead 

 leaves; glandular throughout; leaves round-reniform, 2 

 cm. wide, crenately lobed, ciliate on the margin and 

 aristate at the apex of each crenature; petioles 1-2 cm. 

 long, glandular and villous, with long spreading white 

 hairs ; the epidermis on the lower surface is loose and 

 puffed out between the veins; scapes 1-2 dm. high, 

 slender, cymose-paniculate, bracts laciniately bristly and 

 glandular-ciliate, 5 mm. long; lowest branches of the 

 panicle 2 cm. long ; calyx 7 cm. long, campanulate, 

 attenuate to a slender pedicel, slightly contracted above 

 the ovary, purplish at the lower part of the tube, paler 

 above, 5-cleft, with round, obtuse, greenish, or purplish 

 divisions, densely hairy above, glandular below; petals 

 exserted, 4 mm. long, with blade equalling the claw, 

 oblong, acute, with a gland at the point of insertion; 

 stamens inserted below the petals on stout filaments, 

 anthers orbicular, orange ; stamens and styles hardly ex- 

 tending beyond the calyx-lobes. 



This Heuchera, notable for its long calyx, is found on 

 the trail to the Antimony Mine in San Egmidio Canon, 

 Kern County. It forms mats covering several square 

 yards. In the fall the leaves turn crimson and it becomes 

 quite conspicuous. 



The specimens from which the description is drawn 

 were collected by Mrs. Jasper, the owner of the mine, 

 in May, 1895. 



The type is in the Herbarium of the California Acad- 

 emy of Sciences. Duplicates have been distributed to 

 the Gray Herbarium and the National Herbarium.
