very frequent in the bottoms. One of the showiest shrubs of this 

 region, the lately-discovered Hypericum lobocarpum, which would 

 make a splendid adornment of every garden, grows copiously 

 around Hollow Eock. It makes a flat-topped bush from six to 

 eight feet high. In the swamps float the water shields (Brasema 

 ' peltata and Gahomba Caroliniana) , while the water chinquapin 

 (Nelumho lutea) rears its big, peltate foliage and large, sulphur- 

 yellow flowers high above the brownish waters of the lagoon. 



Of other frequent aquatics I may only mention the Limnanthe- 

 m,um lacunosum, Banwn^^ulus multifidus, Utricularia hiflora. Spe- 

 cies of Lemna, Wol-ffia, and the neat Azolla cast a green veil over 

 the quiet pools. The Indian rye {Zizama aguatioa), a tall grass, 

 which the Indians used to harvest, using the grains for mml,- is 

 bere in its proper sphere, aaid its tall heads look down upon patches 

 of sword lilies. Iris cuprca, and Iris hexagona; and all the swampy 

 "flats are filled with Scirpus dehilis. Varices, and Bhynchosporas. 



On higher grounds congregate Dalea ailopecuroi-des, Galium Ar- 

 Tcansanum, Eryngium prostratum, MarshMlia lanceolata. Ambrosia 

 bidentata, Helmium tenuifolium, Senecio lobatus, Hydrolea af- 

 finis. Verbena stricta, Polypremum procumbens, Stillvngia syl- 

 "vatica, Lithospermum angustifolium, Habenaria virescens, Juncus 

 militaris, Spartina cy^osur aides, Aristida ramasissima. 



From the suburbs of Memphis I received the elegant Erogrostis 

 oxylepis. On the sandy shores of the Mississippi River abounds a 

 species of horsetail, the Eguisetum robustum, and the invidious 

 burgrass that sticks to clothing and spoils the vlieses of the sheep 

 with its sticky spikes. {Cenchrus tribuloides.)
