The only insects found visiting the plants were two species of ants, 

 and a very small but active grasshopper. Not only is there a drop of the 

 richest and sweetest nectar at the base of the style, but the cells of 

 the entire flower are saturated with saccharine material. The flowers 

 are frequently found with stamens, style, and a large portion of. the 

 corolla eaten away. The actions of the grasshopper are noteworthy. 

 From his position in the heart of a flower he will leap lightly up 

 through the anthers above him, and alight, possibly in or upon 

 another flower, but more frequently upon a spine of the plant, which 

 he will neatly grasp, preventing himself from being impaled. In this 

 way the pollen is unavoidably scattered. I was unable to catch one 

 of the active little creatures, so I cannot say what appendages or ar- 

 rangements he may have for conveying the pollen about his person. 



In conclusion, I would remark that a large plant, consisting of 

 many heads or stems, grew in the dooryard of a house where I spent 

 some time. While the plant was blooming I watched it closely for 

 the appearance of insects, but could never see any upon it. It pro- 

 duced no fruit, nor, as I was informed, has it done so during the 

 years that it has grown and bloomed there; a fact which may, or 

 may not be significant.

87. Fasciation. — Instances of this deformity appear, to be very 

 frequent this season. I have lately had sent me from this neighbor- 

 hood a specimen of Leticanthemum vulgare^ L3m,, in which two heads 

 were united at the summit of the flattened stem. Now, I have a re- 

 markable specimen of Rudbeckia hirta^ L., in which four heads are so 

 united, forming a rosette of considerable beauty.

 found with B. lanceolatum^ B, matrtcariaefolium and B. Virginianum.

89. Plant Exchanges. — ErtcaceaeWanted.— lam anxious to 

 obtain flowers and buds, in all stages of development, of the rarer 

 and less accessible species of the Ericaceae, and will be glad to ex- 

 change for them species of plants from New Mexico,

For Exchange. — I have found within the limits of this city, 

 Carex tetanica^ Schk., C, Muhletibergii, var. enervis, Boott, very dis- 

 tinct; also the genuine Eragrosiis pilosa, Beauv., and E. Purshii, 

 Schrad. The latter, as I understand it, also according to Dr. Geo. 

 Vasey, has often been regarded by many collectors as E. pilosa^ 

 though it is very different. I will send any or all of the above to any 

 one for my desiderata.

For Exchange.— I have for exchange, Fetalosiemon foHosus, 

 which grows abundantly in this neighborhood in a single locality 

 the only one that I know of in Illinois,
