2. Radicula* glabra (O. E. Schultz) 



Nashirti7ini pahistre subsp. Jiispidiun var. glabruni O. E. 

 Schultz, loc. cit. 516. 1903. 



This is a robust plant, often 6 dm. tall, with large, deeply 

 pinnatifid leaves, quite glabrous, except for a few long hairs at 

 the margins of the petiole-bases ; the silicles are ovoid-globose, 

 only a trifle longer than thick, 2-2.5 '^"i- '•'' diameter, but the 

 septum elongates and narrows as the valves and seeds fall away, 

 becoming 4-5 mm. long. Its relationship is with R. hispida of 

 continental North America, reported also by Schultz from Haiti. 

 Radicula glabra is well illustrated by Curtiss' no. 672 from 

 Bejucal, Cuba ; Mr. Schultz based the name upon Wright's no. 

 1862 from Cuba, and I know the species only from these two 

 collections. It appears to me quite as different from either R. 

 palustris (L.) Moench or R. hispida (Desv.) Britton as the fol- 

 lowing species is from the Floridian R. Waltcri (Ell.) Greene. 



3. Radicula brevipes (DC.) 



Nastitrtium palnstrc var. brevipes DC. Syst. 2 : 192. 1821. 



y\''rt'jr///;'/'/7/;;/ ^r^'z/^ Griseb. Mem. Amer. Acad. 8: 154. i860. 



Nastitrtiinn tanacctifoliiim var. insidarnni Robinson in A. Gray, 

 Syn. Fl. N. A. 1' : 149. 1895. 



Moist or wet situations, Cuba, Santo Domingo, Porto Rico. 



Mr. Schultz proposes a variety puinilum of this species, citing 

 as type Wright's no. 1562 from Cuba; our specimen of that 

 number seems to be merely a depauperate state of the species. 



4. Cardamine pennsvlvanic.a. Muhl. ; Willd. Sp. PI. 

 3: 486. 1 801 



Schultz records this from Haiti, on the evidence of specimens 

 collected by Poiteau, preserved in the Ventenat and Delessert 

 herbaria. Our collectors have not found it on that island. He 

 ranks it as a subspecies of the European C. flcxuosa Withering, 

 but I regard these species as quite distinct. 



As to the introduced species, I record the following data of 

 distribution additional to those cited by Schultz : 



* RadicuI-A (Dillen) Hill, Brit. Herb. 264. 1756. Roripa Scop. 1760.
