JUNCOIDES IN THE SOUTHEASTERN STATES 



By John K. Small 



While collecting about the summit of Table Rock in western 

 North Carolina, in company with Mr. Heller, specimens of a 

 species of Juncoides in every way smaller than the so-called 

 Juncoides campestre were gathered and found to be bulblet-bear- 

 ing at the base. Further investigation showed that the same 

 form had previously been collected on Lookout Mountain, Ten- 

 nessee, by Prof. A. Wood and had by him been described under 

 varietal rank, he evidently not thinking it worthy of being con- 

 sidered a species. Later experience with the genus in the South- 

 east has led me to the conclusions expressed in the following 

 brief synopsis. 



Juncoides Adans. 



Differs from Junc?cs by its closed leaf-sheaths, the I -celled 

 ovary with basal placentae which support 3 ovules and later 3 

 seeds. 



Key to the Species. 



Peduncles terminated by i or rarely 2 flowers : capsule of an ovoid type. 1. J. pilosum. 



Peduncles terminated by compact spikes : capsule of an obovoid type. 



Sepals and petals 3-4 mm. long : capsules much surpassed by the perianth. 2. /. echinatum. 



Sepals and petals 2-2.5 mm. long: capsules surpassing the perianth or about equalling it. 



3. J. bulbosum. 



i. Juncoides pilosum (L.) Kuntze. Stems 1-3 dm. tall, 2-4- 

 leaved. Leaf-blades 3-8 mm. wide, webby, blunt and almost 

 gland-like at the apex : peduncles filiform, equal or nearly so : 

 perianth 2.5-3 mm - l° n g \ sepals and petals triangular-ovate, 

 brown except the hyaline margins : capsule usually about ^ 

 longer than the perianth, sometimes but slightly longer.
