MAIiVACEAE.

Malva rotundifolia L., the Low Mallow, also an Old World species, dif- 

 fers in having larger leaves, and carpels pubescent and not reticulated on the 

 back. It has been recorded as found in Bermuda by Reade, by 11. B. Small 

 and by Millspaugh, but the records probably refer to the preceding species. 



Malva sylvestris L., the High Mallow, European, an erect species with 

 flowers I'-IV broad, the petals much longer than the calyx, is recorded by Reade 

 as escaped from gardens prior to 1883, and mentioned by II. B. Small as 

 escaped and fairly naturalized, has not been seen by us in Bermuda.

 branches of the same number, stigmatic at the summit only, forming capitate 

 stigmas; carpels indehiscent or imperfectly 2-valved, falling away from the 

 axis at maturity, their apices pointed or beaked. Seed ascending. [Greek, 

 star-mallow.] About 75 species, natives of America and South Africa. Type
