Victorian Plants. 13 



61. Calyx undeveloped. 



Woody, rarely almost herbaceous plants, some species tall 

 trees ; calyx absent or rudimentary ; petals always four, 

 connate, sometimes partly seceding from each other, con- 

 tiguous at the margin before expansion ; stamens always 

 four, opposite to the corolla-lobes ; style one ; stigma 

 undivided ; ovulary one-celled with one or more not 

 rarely numerous ovules ; fruits free from each other 

 or strobilaceous-connate, often dehiscent and somewhat 

 oblique, without real dissepiment, and thus representing 

 solitary fruitlets ; albument always absent ; seeds one or 

 more, provided with outer membranes, but the embryo 

 not rarely seceding therefrom. Figures 67 to 73.

62. Corolla continuous with the calyx-tube. 



Herbaceous or woody plants, some species trees but 

 then seldom tall, sometimes parasites on roots ; lobes of 

 the corolla contiguous at the margin before expansion ; 

 stamens four or five, opposite to the corolla-lobes ; ovulary 

 one-celled ; ovules one to five, pendent from a distinct 

 central placentary ; fruit never dehiscent, without any 

 dissepiment ; seed solitary, unprotected by integumental 

 membranes (testa and endopleura) ; albument always 

 present. Figures 64 and 65. Saiitalaceae. 298

64. Stipules present. 



Herbs, shrubs or trees; leaves never compound, rarely 

 denticulated, never lobed, unless rarely by a basal sinus; 

 stipules between the bases of the leafstalks often connate; 

 flowers almost always symmetrical; stamens disconnected, 

 generally as many as corolla-lobes and alternating with 

 them; ovulary with two or more cells, rarely with only 

 one cell; fruit usually with one or more longitudinal 

 dissepiments. Figure 75. Rubiaceae. 303 



Stipules absent. 



Herbaceous or oftener woody plants, some arborescent or 

 climbing; leaves simple or not rarely compound; flowers 

 symmetrical or unsymmetrical; lobes of the corolla three
