female stage, though they may pollinate them while crawling 
over the head in search of pollen. 
As in B. ciliata the tubes are about 8 mm. long. On ac- 
count of its shady situation, the plant is not so abundantly 
visited as in the preceding, and the list shows some peculiari- 
ties: viz., the scarcity of butterflies and the abundance of Sty- 
logaster. On account of the later time of blooming — June 
21 to Sept. 3— the list shows males of Bombus, Augochlora 
and Halictus. On 7 days, between June 26 and July 21, I 
noted the following list : —

Lophanthus nepetoides Benth. — The flower is figured and 
described by Foerste, in Am. Nat. XVIII., 928. The corolla 
is greenish-yellow. The stamens and style are exserted as 
far as 3 mm. beyond the corolla, so that the anthers and 
stigma are entirely unprotected by it. The stamens are 
strongly divergent. While the anthers are discharging pollen, 
the style is bent upwards, but afterwards it bends downwards, 
so as to hold the receptive stigma near the axis of the flower. 
The stem and branches are terminated by close spikes in 
which the flowers are crowded. The flowers are visited by 
insects crawling over them, as Foerste has observed, and since 
the organs are exserted, the visitor is dusted indefinitely onall 
sides, and not on the back as would be the case if the flower 
had not lost its nototribe character. 
On one occasion I found, at the summit of a Sis a 
flower with five stamens of equal length. The corolla showed
