five scales, conniving, and forming a conical roof over the tube, and answering 

 to five external pits, in Comfrey (figs. 268, 260) ; furnished with five emargiuate 

 scales, in Borage (fig. 267) ; and bearing a crown of long, narrow, cut scales, iu 

 Oleander. 



The monopetalous limb is bi- multi-partite, when the petals 

 cohere at their bases only (Pimpernel, fig. 277 ; Borage, fig. 267) :

bi- multi-fd, when they cohere about half-way up, and the sinuses, as well 

 as the segments, are acute (Tobacco, Campanula, fig. 270) ; bi- multi-lobate, 

 when the segments are obtuse or rounded (Myosotis, figs. 263, 

 264 ; Heliotrope, figs. 2r>9, 260 ; Bugloss, fig. 265 ; Comfrey, fig. 

 268) ; toothed, when the segments are very short (Heath, fig. 

 276). 



The regular monopetalous corolla is tubular (c. tubulosd), when 

 the tube is long and the limb erect and continuous with it (Cerinthe, 

 fig. 271). The central flowers, called florets (flosculi), 

 of Chrysanthemum (fig. 272) and allied plants with in- 

 volucrate heads, have small tubular corollas. Such heads 

 are called flosculose. They are infundibuliform (c. infundi- 

 7d. Heath, buliformis), when the tube insensibly widens upward- 

 vcr ' like a funnel (Bindweed, fig. 273) ; hypocrateriform (c. hy- 

 pocrateri-formis or -morplia), when the straight and long tube abruptly terminates 

 in a flat spreading limb, like an antique patera (Lilac, Jessamine, Periwinkle, fig. 



27.">. Canipimula.
