20. Antennaria neglecta Greene. Field Cat's-foot. 



This is the earliest of the Composite of our region.- I have 

 found it blooming from April 26 to May 15. 



In the staminate flower the cup has a diameter of nearly 1 mm. 

 at the entrance and a length of fully 1 mm. Its corollar lobes are 

 spreading. The lower portion of the corolla (between cup and 

 rudimentary ovary) is 2>^ mm. long, and very narrow. Numerous 

 sweeping hairs appear on the upper part of the style, and especi- 

 ally on its very short branches, but there is not a trace of stig- 

 matic papillae. A head of staminate florets is 5 to 6 mm. wide, 

 and 6 to 7 mm. long, and a number of these heads (usually 6) 

 form an inflorescence about 15 mm. in diameter, the marginal 

 florets of which are the first to open. 



In the pistillate flower the corolla is entirely wanting, and the 

 flower consists of a slender style 7 mm. in length, and an ovary 

 1 mm. long. The style is much thinner than that of the stami- 

 nate flower, and its long slender branches are entirely without 

 sweeping hairs, but are furnished with numerous stigmatic papillae 

 on their inner surfaces. The heads composed of pistillate flowers 

 are longer, and more slender than those with staminate flowers, 

 and are more loosely grouped in forming an inflorescence. 



Both staminate, as well as pistillate flowers are abundantly 

 visited by insects, especially by Andrenidae and Syrphidse.
