XCV111 ADDENDA TO THE 



P. 448. 



Spiraiithes graminea, Lindl. ? has been detected in New York and 

 New Jersey by C. F. Austin, and some other species or forms are apparently con- 

 fused with S. cernua. They must be studied hereafter with fresh materials, and 

 identified with Lindley's various species. 



P. 459. 



2. Iris cilprea, Pursh. Stem tall and slender; leaves linear-sword- 

 shaped (' wide); flowers copper-colored, or dull yellow tinged with blue, the 

 tube longer than the ovary. Cairo, S. Illinois, growing with I. versicolor, Dr. 

 Vasey. Common in the Southern States. 



P. 460. 



PARDINTHCTS CmNENSis, Ker, described in Garden Botany, p. Ixxxii., 

 Ixxxiii., has escaped from gardens in some places, and is established along road- 

 sides in Delaware, Wm. M. Canby. 

 P. 461, 465, 472. 



The anthers are so attached to the filament as to be really extrarse in Medeola 

 (as ascertained by Prof. H. G. Clark), and in Lilium (as shown by Dr. Chap- 

 man), Hemerocallis, &c. Other distinctions having also given way, it becomes 

 apparent that Smilaceae and Melanthacese will hereafter be merged in the great 

 order Liliaceae. 



P. 488. 



4. Xyris torta, Smith. Scape terete and one-edged, slender, 9' -20' 

 high, from a bulbous base, and with the linear-filiform rigid leaves becoming 

 spirally twisted ; lateral sepals winged on the keel and fringed above the mid- 

 dle. Pine barrens of New Jersey (near Batsto, D. C. Eaton) and in the S. 

 States ; in dry sand. 



P. 497. 



10. EleocliariS compressa, Sulliv. This is common in Illinois and 

 westward, in a taller form, with elongated and many-flowered spikes ('-!' 

 long) : the style is 2-cleft, the achenium when well formed is smooth, or nearly so, 

 with a rather large tubercle ; the hypogynous bristles generally present, shorter 

 than or surpassing the achenium, and retrorsely barbed. The species should 

 stand after no. 6. 



P. 498, 500. 



l a . ScirpllS paiicifldrus, Lightfoot. Culms striate-angled, 3' - 9' high ; 

 the sheaths leafless ; spike ovate, chestnut- colored ; glumes nearly 2-ranked, 

 blunt, the lower and larger ones not equalling the uppermost ; bristles 3-6, re- 

 trorsely barbed, about the length of the conspicuously beak -pointed triangular 

 achenium. Watertown, near Lake Ontario, New York, Dr. Crawe (mistaken 

 for S. planifolius) ; Point de Tour, Lake Michigan (State coll.) ; Ringwood, N. 

 Illinois, on the borders of a pond, Dr. G. Vasey. Also in the Rocky Mountains. 

 This and Eleocharis no. 7, with other species, serve to combine Eleocharia 

 with Scirptis. (Eu.)
