small flood-plain in one of the ravines of the First Watchung 

 Mountain near Bound Brook. D. laciniata occurs commonly in 

 this flood-plain under similar conditions, and in many parts of 

 central New Jersey, but D. heterophylla has been reported from 

 only a few stations, namely, Mercer and Hunterdon Counties, 

 and at Far Hills, Somerset County, 10 miles north-west of the 

 station in the Watchung and in the same drainage system 

 (Raritan River). It is a fairly frequent plant of the Piedmont of 

 Maryland and Virginia, according to the writer's observations, 

 but appears to have its northern limit in Somerset County, N. J. 



Rhododendron canadense (L.) B.S.P. It came quite as a sur- 

 prise to have one of the Rutgers graduates report the occurrence 

 of rhodora on the coastal plain only a few miles from New 

 Brunswick. A visit on 14 May to a flat boggy field near New- 

 market confirmed the identification. A single specimen was 

 found in bloom in an open thicket bordering a piece of wood- 

 land. Although stations for this plant are known from the high- 

 lands of Morris and Sussex counties, no reports have been found 

 as to its occurrence in this part of the state, or so far south. 

 Newmarket lies on the outwash of the terminal moraine; is it 

 not probable that after the Glacial Period northern species were 

 left stranded in favorable positions, of which this is one? 



Pogonia divaricata (L.) R.Br. This southern orchid has ap- 

 parently been observed in New Jersey only a few times. Stone 

 (I.e.) records its discovery at Batsto (south edge of Burlington 

 county) in about 1860. It has also been collected in Cape May 

 county by Stone, and at Quaker Bridge as late as 1915 by K. K. 

 Mackenzie (specimen at New York Botanical Garden). It was 

 accordingly a matter of much interest to the writer to find sev- 

 eral plants on 2 July in the Speedwell region, in what Stone 

 calls "the innermost recesses of the pine barrens." In agree- 

 ment with Stone's observations, the plants were found in much 

 drier spots than are the home of P. ophioglossoides. The flower 

 is more striking than beautiful, with its stiff dark-colored sepals 

 and peculiar magenta lip. 



Specimens of these plants are deposited in the Herbarium 

 of Rutgers University. Further reports of any of these plants 

 will be welcomed by the writer.
