304 SYNGENESIA — SUPERFLUA. ISenecio. 



— a. and /3. arc l)oth mentioned as (^rowing on Bon Lawcrs, by Sir J. E. 

 Smith. Fl. July. If. — Hairy or hispid, like the last ; but with leaves 

 much longer in proportion : — 3 — 5 inches high, simple, with rarely more 

 than onejiower at the summit. 



33. Aster. Linn. Starwort. 



1. A. Tripolium, h.(Sca Starwort,or 3Hchaelinas Daisy); stem 

 glabrous corymbose, leaves linear-lanceolate flesliy obscurely 3- 

 nerved, scales of the involucre lanceolate membranous obtuse all 

 imbricated. E. Bot. t. 87. — Tripolium vulgare, Nees. 



Salt-marshes, frequent. Fl. Aug. Sept. 1|. — I — 3 feet high. Tlie 

 florets of the ray are sometimes wanting. 



34. Senecio. Linn. Groundsel. 

 * Flowers without rays. 



1. S. vulgaris, L. (^common Groundsel); leaves semiamplexi- 

 caul pinnatifid toothed, flowers in clustered corymbs destitute 

 of a ray. E. BoL t. 747. 



Waste ground, fields and hedges, abundant. Fl. all summer. 0. — 

 A span to a foot high. Flowers small, yellow. Birds are fond of the 

 buds and young leaves. 



** Flowers rayed, with the ray rolled back. 



2. S. viscosus, L. (stinking Groundsel); ray revolute, leaves 

 pinnatifid and viscid, scales of the involucre lax hairy, stem 

 branching diffuse. E. Bot. t. 32. 



Waste ground, especially on chalky or gravelly soil, in many places. 

 Fl. July, Aug. 0. — Stems 1 — 2 feet high, much branched and spread- 

 ing : — remarkable for its viscid hairs and fetid smell. d| 



3. S. sylvdticus, L. (monntaiti Groundsel); ray revolute some- 

 times wanting, leaves sessile pinnatifid lobed and toothed often 

 eared at the base, outer scales of the involucre very short gla- 

 brous, stem erect straight, flowers corymbose. E. Bot. t. 748. 

 — /3. leaves distinctly eared and amplexicaul at the base. S. 

 lividus, L.9—E. Bot. t. 2515. 



Dry upland soils, banks, and gravelly pastures. Fl. July. 0. — 1 ft. 

 high. Leaves finely divided. Plant with a disagreeable smell, but not 

 so powerful as 5'. viscosus. The aS. lividus of Linn, is a Spanish species, 

 and unknown to me; but whatever it is, I fear the plant of F. Bot. can- 

 not be considered specifically distinct from the present. I form my opi- 

 nion from Mr Middleton's original specimens, now before me. Mr W. 

 Wilson does not think it distinct ; nor does Mr Richmond, (JVat. Mag. 

 for Mar. 1830,7?. 197,) who observes that the green tips of the cal. 

 scales, upon which much stress is laid, eventually become brown. 



*** Flovjers with patent rays. Leaves pinnatifid. 



4. S. squdlidus,'L. (inelegant Ragioort); ray spreading its corol- 

 las elliptical entire, leaves glabrous pinnatifid with distant oblong 

 and toothed segments. E. Bot. t. 600. 



On walls in and about Oxford. Walls and rubbish at Biddeford, Devon. 

 Fl. June — Oct. A most distinct species, but which I have hardly
