94-9. Doronicum Pardalianches Linn, is reported to be a poi- 

 sonous plant. 



CALENDULA. 



Heads many-flowered. Florets of the ray ligulate, ? ; of the 

 disk tubular and $ ; the corolla of all hispid at the base. Involucre 

 in few rows, with distinct scales. Receptacle naked, flat. An- 

 thers caudate, subulate, short. Style ending in a knotty hispid 

 cone, bifid at the point ; of the ray short, with 2 long slender 

 stigmas, smooth below, glandular above. Ovary arcuate, fertile. 

 Achaenia produced by the ligulate florets, all without pappus, 

 usually arranged in 2 or 3 rows ; the outer more or less rostrate ; 

 the intermediate truncate at the apex, prickly at the back, more 

 or less curved, with their sides extended into an entire concave 

 or flat incised membrane; the innermost annular or incurved, 

 muricated at the back, all (especially the innermost) fertile.

 DC. prodr. vi. 451. Fields in the South of Europe. 



Root annual, fibrous. Stem about a foot high, with many patent, 

 dichotomous, or sometimes trichotomous branches, striated, green, suc- 

 culent, hispido-pubescent. Leaves oblong, acute, somewhat succulent, 

 broad, and a little cordate at the base, the margins quite entire, often, 

 as well as here and there upon the surface, hispid with short hairs. 

 Flower-heads large, terminal, solitary upon each branch, of a rich, full 

 golden yellow, deeper and brighter previous to their full expansion. 

 Involucre of many nearly equal, appressed, linear-subulate, pilose- 

 hispid leaves or scales, not A so long as the radiant florets, the apices 

 a little recurved. Corollas of the ray ligulate, female tridentate, broadly 

 linear, the lower tubular portion hairy. Ovary singularly boat-shaped, 

 curved like a horse-shoe, large, green, downy within, having a thickened 

 margin, more or less tuberculated on the back. Florets of the centre 

 all tubular, small, male, and consequently sterile; the mouth 5-cleft, 

 base hairy. Abortive ovaries cylindrical, downy, green. Receptacle 

 dotted. The heads of fruit have a singular appearance : the centre or 

 disk is occupied by the closely packed, abortive pistils, and is surrounded 

 by the numerous, large achaenia, which constitute the circumference, 

 and are cyinbiform, with a broad, thickened margin, singularly incurved, 

 within at the base having an elevated lamella, the back furnished with a 

 tuberculated ridge ; the inner of these achaenia are more narrow, and 

 have less margin. Hooker. It was formerly much employed as a car- 

 minative; it is chiefly used now to adulterate saffron.
