CONVOLVULUS FAMILY. 



CONVOLVULACE^. 

 Upright Convolvulus. Ccmvohulus spithamwus. 



Found in June, growing on dry and sandy places, in the open. 



The stalk is seldom over 10 inches in height, single, leafy, and 

 erect ; it is round, and downy with small hairs. Pale green in color, 

 but red near the foot. 



The leaf is between 1 and 2 inches in length, oblong, with tapei' 

 tip, and a narrow heart-shaped base ; it is folded slightly on the 

 midrib ; all the ribs show plainly, the margin is entire, and the surface 

 is roughened by hairs ; in color a full green, somewhat lighter under- 

 neath, with a pinkish tint along the edge and the midrib. It is set on 

 a short, downy, reddish stem. The arrangement is alternate. 



The flower is large; the corolla a beautiful vase shape with a 

 rolling, slightly 5-angled rim, in texture fine and thin, the outside of the 

 throat shining ; within the vase, at the bottom, may be seen 5 deep 

 pits ; it is of a pure and exquisite white, toned to creamy-green near 

 the calyx ; the 5 stamens are cream colored while the 2-tipped pistil is 

 white. The greenish calyx is 5-parted with small pointed divisions 

 which are almost concealed by the 2 longer, pale green bracts that 

 clasp together closely about its throat. The flower is set on a rather 

 large, flat, downy, pale stem which rises from the angle of a leaf. The 

 plant bears but few flowers. 



Far less common than the Bindweed this flower must be reckoned 

 a treasure-trove by its finder. Its texture is so thin that the calyx- 

 color glows within the throat of the vase with a golden green effulgence.
