APOCYNACEAE, 
Amsonia Cruata, Ma., R.— The stem is terminated 
by a conspicuous panicle of pale bluish flowers. The 
corolla is tubular, with a border of 5 lobes. It meas 
ures 14 mm. across. The tube is slender and measures 
7 mm. in length. In the upper part, occupied by the 
anthers and stigma, it is broader. The throat is densely 
bearded, shielding the pollen from intruders. 
The anthers surpass the stigma, so that self-pollina- 
tion is not likely. The pollen is discharged in a mass- 
The stigma is lateral and appears quite viscid. When es 
insect inserts its tongue the viscid matter may readily 
adhere to it and catch the pollen. 
Long-tongued bees commonly show a mass of pollen 0? 
their maxillary laminae, but butterflies never do. It is 
doubtful whether butterflies ever earry the pollen. Mr. 8-
