Lonicera L. Caprifoliaceae. 100 %. L. Periclymenum L. (honey- 

 suckle or woodbine), and others, in Brit. Mostly erect shrubs, a 

 few twining, with opp. frequently connate 1. In the axils of many 

 (e,g. L. tatarica L.) are serial buds, of which the lowest gives rise to 

 the fls. usu. in pairs, the central fl. of the small dichasium not being 

 developed. The fl. is frequently [ , and gives rise to a berry. In 

 some the pair of fls. produces two independent berries, in others the 

 berries fuse into one as they form. Some sp. exhibit the 'fusion' 

 even earlier; and one finds two corollas seated upon what at first 

 glance appears a single inf. ovary. Dissection shows that in most 

 cases the two ovaries are side by side, free from one another, in a com- 

 mon hollow axis ; in a few cases, however, the union is more complete. 

 The fl. of the honeysuckle is visited chiefly by hawk-moths (at night). 

 The fl. opens in the evening, the anthers having dehisced shortly 

 before this. The style projects beyond the anthers. The fl. moves 

 into a horiz. position at the same time. At first the style is bent 

 downwards and the sta. form the alighting place for insects. Later 

 on the style moves up to a horiz. position, the sta. shrivel and bend 

 down, and this is complete by the second evening when the next 

 crop of buds is opening. At the same time the fl. has changed from 

 white to yellow. The length of the tube keeps out all but very long- 

 tongued insects (class F).

Lopezia Cav. Onagraceae (2). 15 C. Am. Fl. -|- . The two upper 

 petals are bent upwards a little way from the base, and at the bend 

 there seems to be a drop of honey. In reality this is a dry glossy 

 piece of hard tissue ; like the similar bodies in Parnassia it deceives 

 flies. There are real nectaries at the base of the fl. There are two 

 sta., of which the post, only is fertile; it is enclosed at first in the 

 ant. one, which is a spoon-shaped petaloid std. In the early stage 

 of the fl., the style is undeveloped and insects alight on the sta.; 

 later the style grows out into the place first occupied by the sta., which 

 now bends upwards out of the way. In L. coronata Andr., &c. there
