CATALOGUE OF SPECIES. 161 



Tricardia watsoni Torr. But. King Snrv. 258 (1871). Type locality, "on foot-hills 

 of Trtii'kee Pass and the Trinity Mountains, Western Nevada; 4-4, 500 feet latitude." 



In Surprise (No. 654; and Willow Creek (No. 837) canons, Panamint Mountains. 

 This peculiar plant lias been found at several widely separated points in Utah, 

 Nevada, and southeastern California, but it appears to be nowhere abundant. Its 

 zonal position is not clear, but in the two places in which it was collected itoccurred 

 near the line between the Upper and Lower Sonoran zones. 



Emmenanthe penduliflora Benth. Trans. Linn. Soc. xvii. 281 (1837). Type 

 locality Californian, but not specifically given. 



This is one of the few plants that grow in the desert as well as the intramontane 

 regions of California. It occurred in Johnson (No. 552) and Surprise (No. 602) canons, 

 Panamint Mountains, at both points in the upper part of the Lower Sonoran zone, 

 and again along the road from Kernville to Caliente (No. 1056), below the chaparral 

 belt. ° 



Draperia systyla (Gray) Proc. Araer. Acad. vi. 37 (1861), under Kama; Torr. 

 Proc. Ainer. Acad. vii. 401 (1868). Type locality, "in the interior of California." 



In the valley of the Kaweah River (No. 1339). This, the only species of the 

 genus, is confined to the Sierra Nevada of California. 



Eriodictyon angustifolium Niitt. PI. (Jamb. 181 (1818). Type locality, "on the 

 Sierra of Upper California." 



In the regions in which the expedition met with this plant and E. californicum 

 the two did not intergrade, and until more is known of the supposed connecting 

 forms in extreme southern California and Lower California, it seems best to treat 

 them as distinct. E. angustifoUum was found only in Mountain Springs Pass, 

 Charleston Mountains. 



Eriodictyon californicum (Hook. & Arn.) Bot. Beech. 364 (1840-41), under Wig- 

 andia; Greene, Pittonia, ii. 23(1889). Type locality Californian. The type speci- 

 mens were collected by Douglas. 



This is the Eriodictyon glutinosum of Henthain. It was seen on the south slope of 

 Cajou Pass (No. 107;, again on the South Pork of Kern River near Kernville (No. 

 1031), and at several points between that place and Tehachapi Valley, growing 

 below the chaparral belt. The species is, therefore, characteristic of the Lower In- 

 tramontane zone of southern California. It is the common verba santa. 



Eriodictyon tomentosum Benth. Bot. Sulph. 36 (1844). Type locality Califor- 

 nian. The original specimens were collected by Douglas. 



It should be noted that if this species proves to be continent with E. crasxifolium 

 Benth., from San Diego, California, that name has precedence over E. tomentomim. 



The plant was collected in the Canada de las Uvas (No. 1142); and was found also 

 bv Dr. Merriam in the valley of Peru Creek, on the south slope of the Liebre Moun- 

 tains. 



Marilaunidium aretioides (Hook. & Arn.) Bot. Beech. 374 (1840-41), under Eutoca. 

 Type locality, "between Burnt and Malheur Pi vers," eastern Oregon. 



Near Willow Creek, Panamint Mountains (No. 765). This species was first placed 

 doubtfully in Eutoca, afterward 1 separated interrogatively as a section of that 

 genus under the subgeueric name Coiutnlhu*, and finally 2 erected into a genus of 

 the same name. The close relationship of the genus, which contains but this 

 Bnecies, with our other desert species of Xama has long been recognized. Ben- 

 tham and Hooker say of it, 3 "Genus a Phacelia paium distinctum habitu, 



i A7DC. Prodr. ix. 295 (1845).
