36 DICOTYLEDONOUS PLANTS. 



** Peduncles many flowered. 



3. H. corymbosuyi Mich. : stemsuftruticose, branching, erect ; branches 

 dichotomous, subpubescent ; leaves alternate, lanceolate-oblong, some- 

 what obtuse, white, tomentose beneath ; upper ones revolute on the 

 margin ; flowers in crowded fastigiate corymbs ; sepals tomentose and 

 whitish hirsute, outer ones linear-obtuse ; inner ovate, acute, scarcely 

 as long as the capsule. 



HAB. Sandy ,fields. N. J. to Geor. June Aug. U> This 

 plant is said by Pursh to have the flowers very small and some- 

 times without petals. On the other hand, Elliott remarks that 

 although the flowers are much smaller than those of H. carol i m- 

 t; n it in. they are nearly equal in size to those of our other species. 

 Perhaps the assertion of Pursh that this and the foregoing species 

 have been mistaken for Lechea major will apply to himself.
