peduncles elongated, capitately many flowered ; glomerate cluster involu- 

 crate with foliaceous bracts; sepals subulate linear, ferruginous-hirsute, 5 

 lines long, nearly equaling the violet corolla. Cult, and waste grounds, 

 from South Carolina and Arkansas southward." (Grray Syn. Flo. N. Am.,

 '' Capsule depressed, somewhat four-sided." 



SOLANACEiE. 



540a. Physalis Philadelphica, Lam. — Quite common at Lovcland, 

 0. Identified during the past summer (1883). 



546. Datura meteloides, D C. — This seems to be the species former- 

 ly given in the catalogue as '^ D. metel, Locke." It is cultivated in old gar- 

 dens and may have escaped to roadsides in some places. The principal 

 characters of the species are as follows: Puberulent or pubescent; 

 leaves ovate, entire or repaud-toothed; corolla six to eight inches long, 

 white or tinged with violet, sweet scented. Native along streams in Texas 

 to Arizona and California. Chapman considers meiel as a good species, 

 but it is probably only a synonym. 



546a. NicoTiANA Tabacum, L. — As this species is being largely culti- 

 vated in this vicinity it is likely to escape and be found along roadsides. 

 It is easily known by the exceedingly large leaves and tall spike of tubu- 

 lar, pinkish flowers. 



EUPHORBTACE^. 



616a. Euphorbia cyparissias, L. — Growing abundantly on a private 

 place near Loveland, 0., and escaped from cultivation. 



. LEMNACE^. 



678. Lemna minor, L. — Given in the catalogue on the authority of 

 Mr. Clark. It has recently (June 1884) been rediscovered at Cummins- 

 ville by Mr. Going. 



NAIADACE^. 



684. Zannichellia palustris, L. — This species credited to Mr. Lea 

 has been lately found by Mr. Going in the same locality as Lemna minor. 

 There are, doubtless, many species of Potamogeton in our streams also. 



TYPHACE^. 



682a. Sparganium simplex, Hudson. — Chester Park. Dr. R. M. 

 Byrnes. 



ORCHIDACE^. 



696. Spiranthes cernua, Richard. — A single specimen of this was
