732. Pennell, Francis W. Scrophulariaceae of the southeastern United States. Proc. 

 Philadelphia Acad. Sci. 71 : 224-291. 1919. — Extensive keys intended to "include all features 

 of evident contrast" are given for the 38 genera and 123 species known to occur in the area 

 from North Carolina to Florida and west to the Mississippi river. The work is based largely 

 upon notes from fresh flowers. Habitat, distribution, date of flowering, color of corolla, and 

 references to herbarium material are given for each species. — Leva B. Walker. 



733. PuGSLEY, H. W. Plantago alpina and P. maritima. Jour. Botany 58 : 149-150. 1920. 

 — It is often with difficulty that dwarf plants of P. maritima are distinguished from plants of 

 P. alpina. In the spring, however, when growth is beginning the two species can be more 

 clearly differentiated. The author discusses these structural and habitat differences as based 

 on plants growing in his garden, where P. alpina flowers earlier and more sparingly than 

 P. maritima. — K. M. Wiegand. 



734. Rehder, Alfred. New species, varieties and combinations from the herbarium and 

 the collections of the Arnold Arboretum. Jour. Arnold Arboretum 2 : 121-128. 1920. — The 

 present article contains two new species of Lonicera, L. subsessilis from Korea and L. demissa 

 from Japan, and the following hybrids, species and varieties based on cultivated plants: 

 X Prunus Arnoldiana, X P. Meyeri, P. Padus var. laxa, Acanlhopanax ternatus, X Viburnum 

 Jackii, and Physocarpus intermedins f. parvifolius. — Alfred Rehder. 



735. Ridley, Henry N. Plantago Cynops L. in Kent. Jour. Botany 58: 271-272. 1920. 

 — The above species, a native of the chalk barrens of southern Europe, was found by Charles 

 Baker on similar chalk downs between Cobham and Meopham in Kent. It is apparently 

 entirely absent from northern France. The Kent downs are peculiar in harboring other 

 plants that are rare in England. — K. M. Wiegand.
