D1COTYLEDONES : GAMOPETALJJ. 



645 



has an obliquely campanulate (digitaliform) corolla ; stamens 4 : D. purpurea 

 is common in woods ; the yellow D. grandiftora is cultivated. Scrophularia 

 has a globose corolla; S. nodosa (Figwort) and S. aquatica are common. 

 Veronica, the Speedwell, has only the 2 postero-lateral stamens, and the two 

 lobes of the upper lip of the (rotate) corolla are united ; the posterior lobe of 

 the calyx is suppressed (Figs. 444 B, 445 C) : V. Anagallis and V. Beccalmnga, 

 are common in ditches ; V. arvensi*, agrestis, serpyllifolia, ChanMedrys, and 

 others in pastures and fields. Sibthorpia has a sub-rotate 5-8-fid corolla, 

 and four stamens ; S. europtea is the Cornish Moneywort. 



Pedicularis, the Lousewort, has a 5-toothed calyx, and the upper lip of the 

 corolla is galeate : Euphrasia, the Eyebright, has a 4-toothed calyx, the upper 

 lip of the corolla has two spreading or reflexed lobes : Bartsia has a 4-toothed 

 calyx, upper lip of the ringent corolla entire or only notched : Ehinanthus, the 



Pro. 445. Flowers of Scrophulariaeeee. A Antirrhinum : fc calyx ; r tube of the personate 

 corolla, gibbous at the base (/i); o upper, u under lip of the corolla; g prominence (palate) 

 of the under lip. B Upper lip of the same, seen from within: s the two longer anterior 

 stamens ; s' the short lateral ones ; st rudimentary posterior one. C Flower of Veronica : 

 Ic calyx ; u u u the three lobes of the lower lip of the rotate corolla : o the upper lip ; s s the 

 two stamens ; n stigma. 



Eattle, has a four-toothed inflated calyx : Melampyrum, the Cow-Wheat, has a 

 4-toothed tubular calyx, and the capsule is few-seeded : all these plants possess 

 chlorophyll, but they are more or less parasitic upon the roots of other plants. 



Order 2. PLANTAGINACEJJ. Flowers regular, isobilateral, and 

 apparently tetramerous, but the true interpretation of them is de- 

 duced from those of Veronica (Figs. 444 B and 446) : the posterior 

 sepal is suppressed, as also the posterior stamen ; the two posterior 

 petals cohere to form an upper lip which is quite similar to one of 

 the lobes of the three-lobed lower lip (Fig. 445 (7) : stamens four, 

 the two anterior not being suppressed : ovary dimerous, bilocular, 

 or sometimes unilocular or spuriously 4-locular : ovules solitary 

 and basal, or numerous : fruit a capsule with transverse dehis- 

 cence, or a nutlet : seed with endosperm.
