of about equal length with the pedicels; corolla-lobes oblong, Avhite 

 with greenish tips ; hoods white, spatulate-oblong, twice the length 

 of the anthers, with a straigiu, thick, obtuse, moderately exserted 

 horn ; anther-wings very broad and conspicuous for the size of the 



flowers, and minutely notched at the base ; column short, but dis- 

 tinct; follicles smooth, ovate, with rostrate-attenuate apex.

4. New Stations for Tillandsia.— It may possibly not be 



generally known to botanists that the "long moss," Tillau^ia usne- 

 Oleics, L., grows on the peninsula of Eastern Virginia ; at"Teast I have 

 seen no record of its occurrence north of the TJismal Swamp. In 

 crossing the peninsula from Cherrystone to Cobb's Landing, this 

 southern parasite may be seen growing at two or three stati0ns,\about 

 half way across; in one place festooning the top of a rather tall holly 

 {Ilex opacd) directly by the roadside, and at another, wreathing the 

 trunks of the large pines {Pinus australis ?) One '' streamer " of at 

 least twelve feet in length was observed. I was informed by an in- 

 telligent inhabitant of the town of Capeville that it extends to the 

 northern limit of Northampton County, or to about the 38th parallel 

 of North latitude.

5. New Finds for New England.— A new station for Pole- 



vtoniiim caeruleiun, L., was discovered a few years since in the Green 

 Mountains. It is in the town of Ripton, Vt., at a small pond 1,500 

 feet above sea-level, and over a mile from any house or clearing. 

 Nearly an acre of the boggy delta of a small brook was covered with 

 thousands of these bright blue flowers. 



In August, 1879, I discovered a few specimens of Zygadenus 

 glaucus, Nutt., growing on the north side of a steep rocky headland of 

 Lake Champlain, near the mouth of Otter Creek. 



Carex, Grayit\ Carey, C. flexilis, Rudge, C forvwsa. Dew., and 

 /uncus Canadensis, J. Gay, var. brachycephalus, Engelm., I find in 

 the vicinity of Middlebiiry, Vt. They have not, I think, been re- 

 ported from this region before.

_ 6. Similarity between the Lichen Flora of Africa and South 



America.— Dr. J. Miiller, of GenevarSwitzerland, in describinsr a re- . 

 cent_ collection of Lichens from the western coast of Africa, calls at- 

 tention to the remarkable fact that although there is little in common 

 between the phaenogamous floras of that coast and the eastern coast 

 of South America, yet out of 40 previously known licJietis in this col- 

 lection 32 also occur in South America. More than half the entire 

 collection, of 60 species is common to both continents. He attrib- 

 utes this to the strong aerial equatorial current which blows steadily 

 from east to west, and can transport such light bodies as the spore's 

 and soredia of lichens from Africa to America, while the seeds of 

 plants are too heavy to be transported in this way. He observes that 

 this means of dissemination renders it necessary to be strongly on
