194 ARTHUR-BISBY— TRANSLATION OF SCHWEINITZ'S 



uredinia. The empty, original packet is labelled inside " Uredo 

 Smilacis S. rotundifol Sal," and outside " Cseoma (Ured) Smilacis 

 LvS in S. rotundifol Salem." 



The rust is the uredinial stage of Piiccinia Smilacis Schw., no. 

 2916, very common in the southeastern states on various species of 

 Smilax. 



2823. 13. C. U. Labiatarum, Lk. n. 34, Syn. Car. [as] U. Clinopodii, 469, and 



Bethlehem on species of Pycnanthemum. 

 (469. II. [Uredo] Clinopodii Sz. 



U. orbicular, somewhat inflated, yellowish. 



Frequent in autumn on the leaves of Clinopodium incanum. 

 Related to U. Menthse.)' 



Represented only by an empty packet, which is labelled inside 

 "Uredo Clinopodii In Pycnanth. Salem," and outside " Czeoma 

 (Ur) Pycnanthcmi LvS C. clinopodii Salem." Without doubt 

 Schweinitz had the uredinia of Piiccinia Mentha; Pers., on Ko cilia 

 incana (L.) Kuntze, of which the preceding names are synonyms. 

 He accepted Link's disposition of his new species as a synonym 

 under Link's name for all the common mint uredinia. 



2824. 14. C. U. Ipomese, [L.v.S.,] Syn. Car. 468, Lk. n. 38, not Pennsylvania. 



(468. ID. [Uredo] Ipomoese Sz. 



U. rather small, sparse, not confluent, bright red. 



Frequent on the lower surface [of leaves] of Ipomoea triloba. 

 Related to U. Tussilaginis.) 



Represented by three cordate leaves, 3 cm. long, mounted, well 

 covered beneath with uredinia and telia, and two smaller leaves at- 

 tached to a slender stem, in the original packet, bearing a few sori. 

 The packet is labelled inside "Uredo Convolvuli Salem," afterward 

 " Ipomoese " written above Convolvuli, and outside "Cseoma (Ur) 

 IpomecE LvS in Ip. pandur. Salem." 



The rust is an excellent example of Colcosporiuni I pomace 

 (Schw.) Burr., showing uredinia and telia, and the host is doubtless 

 7. pandurata L., which was at first confused by Schweinitz with the 

 more southern species, /. triloba. Although Schweinitz incidentally 

 omitted his initials as author of the specific name in accordance 

 with his custom in other similar instances, L. v. S. should be added,
