THE FLORA OF LOUISIANA 191 



Physalis carpenteri. This Physalis was first collected by Car- 

 penter in West P^eliciana in 1840 and was named in his honor by 

 Riddell with whom he was associated in botanical work in Louis- 

 iana. The species is extremely abundant in ravines and rich 

 woods in West Feliciana where it frequently occupies large tracts 

 of ground to the exclusion of any other species. I have never 

 observed it in any other parish in Louisiana. 



Drymaria cordiformis Wild. This species which is as far as I 

 can discover recorded here for the first time in the United States 

 was identified for me by Dr. B. L. Robinson of Harvard University. 

 It is widely spread over Louisiana, very rare in East Louisiana, 

 extremely abundant near Opelousas, West Louisiana where it 

 forms thick carpets in rich woods. 



Ipomaea wrightii. This species is not included by Small in 

 his Flora of the Southern States. It is widely spread in Louisiana 

 having been collected by me on the edges of Lake Charles, in the 

 swamps of New Orleans, and in swampy places West Feliciana. 

 It is readily distinguished from all other species of morning glory 

 in that the peduncle of the flower is transformed into a tendril 

 by means of which it climbs round low shrubs and grasses.
