31. E. oblongifolium, Benth. Eriog. & in DC. I. c. Gracilius, 

 spithamseum ad pedalem ; f'oliis oblongis ovalibusque basi saepius acutis ; 

 involucris glabratis G-8-dentulis ; perigonii segmentis oblongo-obovatis. 

 — California, along tbe coast, with the same range as the preceding, of 

 which it is likely to prove a smaller or depauperate and narrower-leaved 

 variety ; the matted tomentum sometimes deciduous even from the 

 lower face of the leaves. Var. /3. ? minus, Benth. in DC, with only 

 five and more prominent teeth to the involucre, is probably different ; 

 but the solitary specimen is incomplete and insufficient. 



§ 8. Capitellata. (Desmocephalorum sp. Benth.) Flos basi baud 

 producta ipsa cum pedicello articulatus : perigonium 6-partitum 

 glabrum vel villosulum, segmentis obovato-oblongis fere aequalibus. 

 Involucra (truncata subdentata) pluriflora, pauca in capitula 

 pi. m. paniculato-cymosa in scapo nudo congesta, nunc tantum 

 gemina, alaria nec-non solitaria. Bracteolre plumosaa. Ovarium 

 glabrum. Embryo incurvus, cotyledonibus latis bre vibus. — Herba? 

 perennes, foliis omnibus radicalibus latis margine sa?pius undulatis, 

 scapis 1 - 3-pedalibus nudis junciformibus nunc fistulosis cum in- 

 volucris mox glabratis vel glabris, floribus (an semper ?) albis. 



32. E. nudum, Dougl. in Benth. Eriog. Foliis subtus cano-(quando- 

 que fulvo-j tomentosis ovatis rarius obovatis basi saspius subcordatis, 

 petiolo plerumque longo gracili ; panicuke dichotomy raniis elongatis ; 

 involucris cylindraceo-campanulatis ore truncato (dentibus 6-8 mem- 

 branula prorsus connexis), alaribus sessilibus ; perigonio extus soepius 

 glabro intus basi nunc parce piloso. E. arachnoideum, Hook. & Arn. 

 Bot. Beech., non Esch. — Oregon and California, chiefly towards the 

 coast. Magnopere variat: 



Var. /3. (E. offline, Benth. in DC.) Sublanatum, nempe scapo in- 

 volucrisque lana araneosa tarde decidua obductis. — Umqua, Pickering 

 and Brackenridge in Wilkes's Expedition ; Jeffries in herb. Kew ; ap- 

 parently a form with foliaceous bracts at the lower nodes of the scape, 

 and the flowers seem to be yellow ! 



Var. y. (pubijiorum, Benth. 1. c.) Involucris interdum fere om- 

 nibus in paniculas ramis solitariis, perigonio extus pilosiore. — Califor- 

 nia, Fremont, Rich, Heermann, Horn, &c. But there are traces of 

 this pubescence in many, if not most, specimens of E. nudum. 



Var. 8. (E. auriculatum, Benth. Eriog.) Petiolis basi interdum di- 

 latatis seu auriculato-dentatis ; scapo nunc inflato ; involucris saepius
