and Sambucus, to short-tongued insects. The Weigelia rosea, 

 like Ribes aureum, changes its color after pollination. 



Honeysuckles. The flowers of Lonicera sempervirens, Ait. 

 are nearly regular, trumpet-shaped, the deep red corolla is 

 conspicuous but has little odor. It projects obliquely up- 

 wards and the corolla tube is lined with hairs. Stamens five, 

 as long as the style; pistil and stamens maturing at the same 

 time. The nectar is secreted in the lower part of the tube 

 and is very abundant. In this locality the humming bird, 

 Trochilus colubris, is a common visitor as are some of the 

 larger Lepidoptera as Papilio turnus. The humming bird, in 

 a single visit, takes the nectar from a large number of 

 flowers. 



In Lonicera Sullivantii, Gray, the flowers are irregular, 

 white with a purple tube, and are borne in clusters. The five 

 stamens are situated above the declined style Nectar is 

 so abundant that it rises in the tube and is protected by a 

 copious development of hairs. It is regularly pol- 

 linated by humming bird Lonicera Tartarica, L. the 

 honey is secreted and lodged in the shallow pouch at the base 

 of the tube. It flowers three weeks earlier and has a pleas- 

 ant odor and is conspicuous because of the color. Apis 

 inellifica and Bombus penns^Voanicus are frequent visitors.

 sunflower {Helianthus annuus) a.nd ox-eye daisy (C%/^«- 

 anthemum leucantJiemum). The so called "flower" is an 

 inflorescence known as a head. In the ox-eye daisy, the 

 flower of the outer row of florets, are transformed into a con- 

 spicuous white strap-shaped corolla known as the ray-flowers. 

 In the sunflower these are yellow but in both cases they serve
