114 GAMOPETALOUS EXOGENS 



Obs. The root of this plant was formerly somewhat noted, as an 

 Indian medicine; but is now neglected. JOHN BARTRAM (in the 

 Appendix to SHORT'S Medicina J3ritannica,J says, it is "called in our 

 Northern Colonies Dr. Tinker's Weed; in Pennsylvania, Gentian; 

 and to the Southward, Fever-root." 



3. T. angUStifftlilim, L. Bristly hairy; leaves lanceolate, 

 tapering to the base; axils mostly 1-flowered; flowers greenish- 

 yellow, sometimes tinged Avith purple. 

 NARROW-LEAVED TRIOSTETJM. 



Stem 1 to 2 feet high, simple, rather slender, clothed with spreading and some- 

 what bristly hairs. Leaves 2 to 4 inches long, and % to 1% inches wide, the long 

 tapering base narrowed almost to a margined petiole, scarcely connate, the mar- 

 gins of the leaves, bracts, and calyx-segments, ciliate-hairy. Corolla about % an 

 inch long, rather slender, glandular-pubescent. 

 Hab. East Nottingham : rare. Fl. May. Fr. 



Obs. Collected in 1852, by Mr. EVAN PUGH, of East Nottingham. 

 This is probably the northern limit of the species. 



TPJBE 2. SAMBIPCEAE. 



Corolla rotate, regularly and deeply 5-lobed ; stigmas mostly 3, sessile. Inflores- 

 cence cymose, or thyrsoid. 



176. SAMBITCUS, Tournef. 



[Gr. Sambuke, a musical instrument, said to have been made of Elder.] 

 Calyx-segments minute. Fruit a globular berry-like juicy drupe, 

 containing 3 or 5 seed-like nutlets. Mostly shrubs, with large pith ; 

 leaves odd-pinnately dissected; leaflets serrate, or laciniate; flowers 

 white. 



1. S. CanadensiS, L. Leaflets 7 to 11, oblong, acuminate, 

 smooth, petiolulate ; cymes flat, 5-parted ; fruit purplish black. 

 CANADIAN SAMBUCUS. Elder-bush. Common Elder. 



Stem 5 to 8 or 10 feet high, suffruticose, and finally woody, nodose, branching. 

 Leaflets 2 to 4 inches long, usually 3 pairs and an odd one. 

 Hab. Thickets; fence-rows, &c.: common. FL June. Fr. Aug. 



Obs. This is a rather troublesome plant, to the farmer, the 

 long roots being very tenacious of life, and inclined to spread ex- 

 tensively along fence-rows and hedges, and even into the fields. 



3. S. pill>ens ? MX. Leaflets 5 to 7, ovate-lanceolate, sometimes 

 pubescent beneath ; cymes at first convex, finally conical, or thyr- 

 Boid ; fruit bright red. 

 DOWNY SAMBUCUS. Red-berried Elder. 



Stem 3 or 4 to 10 or 15 feet high, rather more woody than the preceding, branch- 

 ing. Leaflets 3 to 5 inches long, usually 2 pairs and an odd one ; flowers greenish- 

 white, often purple, externally. 

 Hab. Thickets; W. Nottingham: rare. Fl. April. Fr. June. 



06s. This species so common on our mountains, and so remark- 

 able for its thyrsoid inflorescence, and scarlet berries, which are 

 ripe by the time the other is in flower has been detected in the 

 South-western extremity of the County, by Mr. NATHAN MILNER, 

 as I learn from my friend JOSHUA HOOPES. In specimens which I 

 have growing, the leaflets are quite smooth on both sides.
