DISPACEyE.— The Teazel Tribe 



Calyx attached to the ovary, surrounded by several more or less 

 rigid, calyxdike bracts ; corolla tubular, with 4-5 unequal lobes ; 

 stamens 4, the anthers not united ; style I ; stigma not cleft ; fruit 

 dry, T-seeded, crowned by the pappusdike calyx ; flowers crowded 

 together in heads like the Compositas, but differing in the rigid 

 bractioles which surround each ; the leaves are usually opposite and 

 without stipules. A small Order of herbaceous plants inhabiting 

 temperate regions, and possessing no remarkable properties. Dis- 

 paciis FulloHum is the Clothiers' Teazle, a plant with large heads of 

 flowers, which are embedded in stiff, hooked bracts. These heads 

 are set in frames and used in the dressing of broadcloth, the hooks 

 catching up and removing all loose particles of wool, but giving way 

 when held fast by the substance of the cloth. This is almost the 

 only process in the manufacture of cloth which it has been found 

 impossible to execute by machinery, for although various substi- 

 tutes have been proposed, none has proved on trial exactly to answer 

 the purpose intended.
