212 ARTHUR-BISBY— TRANSLATION OF SCHWEINITZ'S 



2859. 49. C. A. Smilacinatum, L.v.S., Syn. Car. 452, Lk. 117, not j-et met 



with in Pennsylvania. 

 (452. 23. [^cidium] Smilacis Sz. 



A. wart-like, convex below, concave above, yellow-red, peridia 

 copious, spores white. 



Here and there on leaves of Smilax rotundifolia and laurifolia. 

 Very distinct. Making thick, conic-cylindric warts on the under side 

 of the leaf. These warts are somewhat truncate and on the pulvinate- 

 truncate part covered with sunken peridia, two lines to a quarter of 

 an inch wide and two or three lines high. Spores white, ratlier large, 

 oval, vesicular.) 



Represented by a nearly round leaf, 5 cm. in diameter, mounted, 

 bearing one group of secia, and by an empty packet labelled inside 

 "^Ecidium Smilacis In S. rotundifol & al Salem," with the addition 

 " Ceeoma Smilacinatum," and on the outside " ^cidium Smilacina- 

 tum LvS Salem." 



This is the secial stage of Piiccinia Smilacis Schw., a rust that 

 is widely distributed in the southern states, and tropical America. 

 The secia are rarely collected, and so far have been reported only 

 from North and South Carolina. The name was changed by 

 Schweinitz to ^cidium (Cceoma) smilacinatum on page 309 of his 

 later work. 



2860. 50. C. A. Aroidatum, L.v.S., Syn. Car. 457, [as A.] Caladii, on Arum 



virginicum, Salem. 

 (457. 28. [^cidium] Caladii Sz. 



A. simple, on very extended areas, peridia rufous-yellow, sphaeria- 

 form, spore-mass orange. 



Frequent in some years on the midrib of the leaves and the 

 stems of Caladium sagittsef olium ; it kills the plants; The closed 

 peridia resemble Sphserias). 



Represented by the middle part, 3 cm. long, of a 5 cm. wide 

 leaf, with over-mature aecia along midrib and large veins, now eaten 

 by insects, and by an empty packet labelled inside " ^cidium Caladii 

 In Calad. Salem," with the later addition " Caeoma aroidatum," and 

 on the outside "^cidium Caladiatum LvS. Salem," with the sub- 

 sequent addition " Aroidat." 



This is the aecial stage of Uromyces Caladii (Schw.) Far!., and 

 on Peltandra virginica (L.) Kunth {Arum virginicum L.), see also 

 no. 2839. The name Ccvoma Aroidatum should have been credited
