to five, overlapping before expansion; stamens disconnec- 

 ted, generally as many as calyx-lobes and alternating with 

 them; ovulary with two or more cells, rarely one-celled; 

 fruit usually with one or more longitudinal dissepiments.

65. Flowers within an involucre of bracts. 



Herbs or shrubs, seldom trees; sap usually limpid, but 

 sometimes also milky; stipules absent; lobes of the calyx 

 contiguous at the margin before expansion; limb of the 

 calyx consisting of hairlets or plumous or scaly or spinu- 

 lous organs (pappus) or quite absent; anthers generally 

 connate around the style; ovulary one-celled ; ovule one, 

 erect; fruit seed-like (achsehium), enclosed in the calyx- 

 tube; seed without albument. Figures 78 to 90.

66. Lobes of the corolla overlapping before expansion. 



Herbs, rarely somewhat woody plants, very seldom climbers; 

 sap limpid; stipules usually absent; leaves scattered or 

 tufted or sometimes whorled; fifth lobe of the corolla 

 often diminutive; stamens two, connate with the style, 

 the whole mostly irritable into spontaneous movement; 

 fruit with a longitudinal dissepiment. (Stylideae.)

67. Stigma unenclosed in any special covering. 



Shrubs or oftener herbs; sap usually milky, often acrid; 

 stipules absent; anthers often connate around the style; 

 fruit generally two- or more-celled ; seeds numerous, 

 seldom few. Figure 91. Campaimlaceae. 365 



Stigma enclosed in a special mostly ciliolated covering. 



Herbs or shrubs ; sap limpid, often bitter ; stipules absent ; 

 leaves usually scattered or tufted ; corolla-lobes five, 

 nearly of the same length, but usually unequal in breadth, 

 often provided with marginal membranes and these at 

 first folded inwards ; stamens five ; filaments disconnected ; 

 anthers seldom connate around the style. Figures 94 

 and 95. Goodeniaceae. 367
