Pig. 91.—Photomicrograph of longitudinal section through a staminate catkin of Comptonia asplenifolia X 10, showing catkin axis (jat), anther-lobe (a), and bract (6). 

Connective.—The continuation of the filament of the stamen that connects the two lobes of the anther.

(B) Detail of flower showing a style surrounded by an extension of the ovary wall at the base. The anthers are provided with basal auriculate appendages.

Common comfrey (5. officinale) is an erect, stout, often branched perennial, to 1 m leaves broadly lance shaped middle and upper ones sessile, but at point of insertion extend downward on stalk stalk distinctly winged flowers variable from white or cream, yellowish to rose, pink, or light to dark violet anther about as wide as filament petal lobes recurved calyx segments distinctly lanceolate nutlets smooth occurs in moist grasslands and riv-erbanks most of Europe, is rare in extreme south, naturalized alien in northern Europe eastern North America. 

Monotypic deciduous tree to 40 m leaves alternate or borne on spurs in clusters of 3-5 parallel veined, broad fan shaped, up to 12 cm, with notch at apex, forming two distinct lobes, hence the species name biloba . Flowers dioecious male flowers on pendulous catkins with numerous, loosely arranged anthers in stalked pairs on a slender axis female flowers are in pairs on long foot-stalks. The drupe-like fruits have an acrid, foul-smelling pulp (likened to dog droppings) surrounding a single smooth, oval, thin-shelled, semi-edible nut (seed). 

C. laevigata is a spiny shrub leaves mostly smooth obovate, three to five lobed, serrulate flowers white to pink with red anthers fruit globose or ellipsoid, deep red found in woods from northwest and central Europe, from England to Latvia, west to the Pyrenees and northern Italy naturalized in eastern North America and India. Many smooth-leaved or slightly pubescent species in Europe have been treated as C. oxyacantha, a synonym for the official European source, resulting in much confusion in the botanical and pharmacy literature. 

A perennial herb with a large fleshy conn from which leaves and flowers are produced in the fall. Flowers violet, throat of perianth bearded, anthers yellow, style armed exerted orange-red subulate tips entire or lobed. Native to the eastern Mediterranean region cultivated as an annual or perennial worldwide (Spain, France, Italy, India, etc.). Part used is the dried stigma 100,0(X)-140,000 flowers are reportedly required to yield 1 kg saffron. Hence, it is the most expensive spice. Major producing countries include Spain, France, Turkey, and India.
