PLANTS OF SOUTHERN NEW JERSEY. 371 



Pogonia divaricata (L.). Spreading Pogonia. 



Arethusa divaricata Linnaeus Sp. PI. 951. 1753 [North America]. 

 Pogonia divaricata Gray, Man. Ed. V. 507. 1867.— Willis 62.— Britton 233.— 

 Keller and Brown no. — Stone, Bartonia II., 26. 1910. 



Open swampy or bogg-y spots, Pine Barren and Cape May 

 districts, very rare and local. 



This splendid Orchid was apparently first collected in the State 

 by D. C. Eaton, at Batsto (in i860?), and again July 7, 1864, at 

 Quaker Bridge, by W. H. Leggett. From that time on there is 

 no evidence of its having been found in New Jersey until June 

 30, 1909, when the writer discovered a small colony of plants 

 near Bennett, Cape May Co., N. J. These specimens were not 

 growing out in the wet bog where P. ophioglossoides abounded, 

 but in a dryer spot near the edge, well concealed among various 

 sedges, grasses, etc. They bloomed again in 19 10 and produced 

 seed, although the farmer's scythe passed within a couple of feet 

 of them and they narrowly escaped being transformed into hay. 



Fl. — June 30 and July 7. 



Pine Barrens.— Ezisto (C), Quaker Bridge (NB). 

 Cape May. — Bennett. 



ISOTRIA Rafinesque. 

 Isotria verticillata (Willd.). Whorled Pogonia.* 

 PI. XLIX. 

 Arethusa verticillata "Muhl.," Willdenow Sp. PI. IV. : 81. 1805 [Pennsyl- 

 vania]. 

 Pogonia verticillata Knieskern 31. — Willis 62. — Britton 233. 

 Isotria verticillata Keller and Brown no. 



Low woodlands ; frequent in the northern counties and less 

 common in the Middle district. Very rare in the Pine Barrens. 



This curious species flowers before the leaves are fully de- 

 veloped. The flower, though rather inconspicuously colored — ■ 

 green and purplish brown — is striking on account of its peculiar 

 structure, the long terete sepals resembling the appendages on 

 the mouth of a cat-fish. 



* The Triphora trianthophora recorded in Keller and Brown's list on the 

 authority of Miss Cora S. Ware (from road beyond Elmer) cannot be verified, 

 and is pretty certainly based on an error of identification. No specimen was 

 preserved, and Miss Ware cannot remember who reported the plant to her. 

 It was thought to have been collected in June, while Triphora does not bloom 

 until August, and is altogether unlikely in the coastal plain.
