easily be seen how the pollen of one flower can fall upon its 

 stigma. It goes to sleep earlier than the other flowers and is 

 more regular in its habits. They sleep during the cold and wet; 

 but it always unfolds somewhat at the proper time, though not 

 entirely unless the sun shines brightly. 



Astragalus lentiginosus is the favorite flower of the bumble 

 bees. Some plants were collected with pistillate flowers, the 

 stamens being small, separate, and with what seemed abortive 

 anthers. It certainly was a singular freak for an Astragalus, but 

 the peculiarity was common on the late shoots of plants already 

 heavy with fruit. I^ater it was seen that the change was due 

 to a fungus. 



Of course there were many other flowers but they were 

 neither particularly admired nor closely observed. A list would 

 necessarily omit so many prevailing later that it would be unfair 

 to the locality and is better omitted. 



A NEW COLLINSIA. 



BY S. B. PARISH. 



Collinsia Davidsonii. Span high, cymosely few-branched, 

 glabrous: leaves inch long, entire obtuse, ovate or oblong, the 

 lower pedicellate, the floral linear-spatulate: verticils few (3-8) 

 flowered: pedicels shorter than the calyx, this three lines high, 

 scarious at base, the thickened obtuse lobes green: corolla mod- 

 erately oblique, its upper lobe pale blue, or nearly white, 

 transversely callous, the ample lobes few- toothed; lower lip 

 equaling the upper, its lateral lobes violet, the keel white with 

 dark tip: filaments beardless: gland stipitate, line high: capsule 

 oval, not surpassing the calyx lobes; ovules four in each cell, 

 seeds rugose. 



Collected by Dr. Anstruther Davidson on the Mojave Desert; 

 at Lancaster, May, 1893. Types in the Gray Herbarium and in 

 my own. A handsome little plant which I have much pleasure 

 ^ in dedicating to its discoverer.
