6 7 8 VERBENA CEAE 



Classification and chief genera (after Briquet): 



A. Infl. spicate or racemose. Ovule usu. basal, erect, anatr. 



i. Verbeneae (no endosperm): Verbena, Lantana, Lippia, Priva, 



Petraea, Citharexylum. 

 2. Stilbeae (endosperm) : Stilbe. 



B. Infl. of cymose type. Cymes often united into panicles, 

 corymbs, &c.; if axillary, often reduced to i fl. 



a. Ovule lat. (sometimes very high up) semi-anatr. Ovary fully 

 or imperfectly 4 ro-loc. 



3. Chloantheae (fr. usu. drupaceous, never caps.; endosperm): 



Chloanthes. 



4. Viticeae (as 3, but no endosperm): Callicarpa, Tectona, 



Vitex, Clerodendron. 



5. Caryopterideae (fr. caps. -like, 4-valved ; the valves fall taking 



the stones with them or loosen them from the placental 

 axis) : Caryopteris. 



b. Ovule apical, pend., orthotr. 



6. Symphoremeae (ov. 2-loc. to centre; fr. dry, i -seeded) : 



Symphorema. 



7. Avicennieae (ov. imperfectly 4-loc. ; fr. caps., 2-valved, i- 



seeded; mangroves): Avicennia (only gen.). 



Verbesina L. Compositae (5). 80 warm Am. 



Verdickia De Wild. Liliaceae (in), i Congo. 



Vereia Andr. = Kalanchoe Adans. (Crass.). 



Verhuellia Miq. Piperaceae. i W.I. 



Verinea Merino. Gramineae (8). i Spain. 



Verlotia Fourn. (Marsdenia EP.}. Asclepiadaceae (n. 3). 5 Brazil. 



Vermiform, worm-shaped. 



Vernal grass, sweet, Anthoxanthnni odoratnm L. 



Vernalis (Lat.), of Spring. 



Vernation (arrangement of 1. in bud), cf. Leaf. 



Vernonia Schreb. Compositae (i). 600 Am., Afr., As., very com- 

 mon in grassy places. Style typical of i (cf, classification of C-). 



Veronica (Tourn.) L. Scrophulariaceae (in. i). -250 extra-trop., many 

 alpine; 17 in Brit, (speedwell). The Brit. sp. are herbaceous (often 

 woody below); fls. in term, or lat. racemes. The post, sepal of the 

 5 typical of this fam. is absent, and the two post, petals are united 

 into one large one, so that the P is 4-merous (see fam. for diagram). 

 The i sta. and style project horiz. from the rotate C. A small per- 

 centage of fls. exhibit a different number of parts (e.g. 5 petals). 

 The fert. of the fl. in V. Chamaedrys L., the commonest Brit, sp., 

 is performed chiefly by drone-flies. The style projects over the lower 

 petal, while the two sta. project lat. Honey is secreted at the base 

 of the ovary and concealed by the hairs at the mouth of the short tube. 

 Insects alighting on the lower petal touch the style and grasp the bases 

 of the sta., thus causing the anthers to move inwards and dust them 

 with pollen. The peduncles stand close up against the main stem of 

 the raceme whilst the fls. are in bud, diverge as the fls. open, and 

 again close up as they wither. Caps, with a few flattened seeds suited 

 to wind-distr. In V. arvensis L. and other sp. that live in damp 

 places, the capsule merely cracks as it dries and only opens so far as
