longioribus ; ovario lineari-lanceolato in stylum perbrevem 

 sensim abeunte, stigmatibus exsertis ; capsula obtuse tiiangu- 

 lata pyramidata acutata atro-rubente lucida semitriloculari 

 longe exserta; seminibus lineari-oblongis multo-lineatis longe 

 caudatis. — J. erythrocarpus, Chapm. olim in sched. 



South-eastern and southern States, from South Carolina, 

 Curtis, Ravenel, Hb. n. 89, to Florida, Chapman, Hb. n. 90, 

 Alabama, Bigelow, and Louisiana, Hale; fl. Sept. & fr. Oct. — 

 Similar to the next but with much smaller flowers, long pro- 

 truding pyramidal capsule, slender stamens inconstant in 

 number and larger seeds. Rigid cespitose stems "from a 

 thick and creeping rhizoma" (Chapman); panicles in most of 

 the specimens before me 2-6 inches in length and quite con- 

 tracted, the principal branch of the panicle being often strict- 

 ly erect and quite elongated, — in others more open ; fruit- 

 heads 2-4 lines in diameter, with 2-4 or 5 flowers ; flowers 

 13- lines long, with very unequal strongly nerved sepals; 

 capsule much longer, sometimes twice as long as flowers, 

 regularly pyramidal from an oval base, deep red brown or al- 

 most black. The number of stamens is quite variable, but 

 more frequently 3 than 6 ; in 40 flowers of eight different spe- 

 cimens, from all the localities mentioned above, I have found 

 only 4 with 6, 9 with 5, 11 with 4, and 16 with 3 stamens, 

 and in no instance did all the flowers of one plant exhibit the 

 same number of stamens. Seeds, without the appendages, 

 0.45-0.50 line long, their length being equal to 2^ or 2^- diam- 

 eters ; appendages straw-colored or white, upper one mostly 

 as long or longer than the seed, lower one stouter and short- 

 er, as is usually the case in the appendages of Juncus seeds; 

 whole seeds with the tails 1-1 -J- lines long; striae of seed very 

 numerous and close. — This may possibly be the same as J.iri- 

 gojwcarpus, Steud. Glum. 2, p. 308, of which I have not been 

 able to obtain a specimen or a satisfactory description.
