 Most are herbs with opp. exstip. 1. (connate in Dipsacus), and cymes 

 (Triplostegia, Morina) or heads of fls. That the heads are also 

 cymose is indicated by the fact that the fls. do not open in strictly 

 centripetal order. The outer fls. have the corolla more or less drawn 

 out on one side (cf. Compositae, Crucilerae, &c.); bracteoles of the 

 ordinary kind are rare (Triplostegia). Most have an epicalyx, a 

 cup-shaped organ springing from the base of the ovary, and usu. 

 regarded as composed of the two united bracteoles. K and C 

 5-merous or 4-merous by union of two members; A 4, epipetalous; 

 G (2), i-loc. with one pend. anatr. ov. Fls. usu. protandr. of the 

 flower class B'. Fr. an achene (cf. Compositae) usu. enclosed in the 

 epicalyx ; endosperm. Several are cult. orn. fl. ; Dipsacus yields 

 teasels. Chief genera: Knautia, Dipsacus, Scabiosa.

Dipsacus L. Dipsaceae. 12 Medit., Eur., Afr. D. sylreslris Mill, 

 (teasel), Brit. The connate leaves form troughs round the stem in 

 which rain-water collects. The protandr. fls. are chiefly visited by 

 bees. D. fullonum L. (fuller's teasel) has hooked bracts; the fr. -heads 

 are used for raising the nap upon cloth {Kew Bull. 1912, p. 345).
