232 Harper : Some plants from Georgia 



the stem stiffly curved through an arc of 45°-6o° between the 

 uppermost cluster of spikelets and the next one below it, a char- 

 acter which does not appear in the type-specimens (Wright's no. 

 3784). Furthermore, it is very unusual for a species growing in 

 the pine-barren ponds of Georgia to be identical with one in the 

 West Indies ; but the structural difference above mentioned can- 

 hardly be considered as of specific value by itself.

 The first locality mentioned by Elliott for his Juncus biflorus is 

 11 10 miles from Savannah, on the road to Augusta." With a 

 view of settling the identity of this species I went to the spot in- 

 dicated on June 18, 1903, and found it to be right in the village 

 of Monteith, Chatham County. I soon saw a plant answering the 

 description, but as its habitat there had been too much damaged 

 by civilization, I went about a mile away before collecting any of it. 

 My no. 184.2, from the vicinity of the nearby station of Meinhard, 

 may reasonably be considered typical. It is essentially the same 

 as a plant which is common in the pine-barrens of Georgia and 

 some adjoining states, and differing from its nearest relatives,/. 

 marginatus and J. aristulatus, by the characters pointed out by 

 Dr. Chapman and Mr. Coville. It is so frequent in Georgia that I 

 will cite only the stations where I have collected it, which are in the 

 following counties : Sumter (478, 483), Screven (784, 788, both 

 from that part of the county which has just been put into the new 

 county of Jenkins), Bulloch {868, an excellent specimen), Wash- 

 ington (1328), Laurens (1373), Charlton (1493), Chatham (1842), 

 and Bryan (1846). Unlike its nearest relatives, it is strictly con- 

 fined to the coastal plain, and grows usually in moist pine-barrens, 

 but sometimes even in dry pine-barrens or on sand-hills. It is 

 said to range from North Carolina to Florida, and it will doubt- 

 less hereafter be found farther west. In Georgia it flowers in May 

 and June.
