6. ERIODICTYON TOMENTOSUM Benth. Bot. Voy. Sulph. 36. 1844. 
Eriodictyon niveum Eastw. Proc. Cal. Acad. IIT. 1:130. 1898. 
Eriodictyon crassifolium subsp. Benthamianum var. niveum Brand, in ENGLER, 
Pflanzenreich 59:140. 1913. 
An erect, branching shrub with the herbage hoary throughout 
with a dense feltlike tomentum or rarely becoming more or less 
denuded and green: leaves thick, elliptic-ovate or obovate, 4—6 cm. 
long, 1-3 cm. wide, cuneate at base, acute or obtuse at apex, 
entire, crenate, or even coarsely dentate, veins scarcely evident on 
the upper surface, beneath reticulate-rugose; panicle terminating 
a usually elongate naked peduncle widely branched or simple; 
flowers crowded, nearly sessile: calyx lobes linear-subulate, equal- 
ing the corolla tube, clothed with white silky hairs with a few 
stalked glands interspersed: corolla white or pale violet, 4 mm. 
long, urceolate, glandular-hirsute without, the tube slightly con- 
tracted below the very short spreading lobes: stamens with the 
free portion of the filaments short, inserted below the throat; 
anthers oval 1 mm. long. 
Until now the identity of E. tomentosum has been misunderstood. ‘TORREY 
(9) first considered it and crassifolium as conspecific, with the remark, “We 
have specimens that are intermediate and Dr. Parry informs me that he has 
seen them in California passing into each other.” We have failed to find in the 
field or in any of the herbaria any intermediate forms, nor is there any eV1- 
dence that Parry ever collected true fomentosum. Geographically and 
structurally, aside from the superficial character of hoariness, these two species 
are more distinct than crassifolium and californicum. ToRREY’s conclusions 
were followed by Gray and other botanists until GREENE (6) discovered a 
plant in Monterey County which he believed to be the true tomentosum.
