1923] The Common Names of Some Trees 91 



separated into a number of species, at least three of which have distinc- 

 tive common names as follows :^ 



Hicoria glabra, black or brown hickory or sometimes broom hick- 

 ory, but of these black hickory seems to be widely known and very 

 appropriate. 



Hicoria pallida, sand hickory. 



Hicoria ovalis {)nicrocarpa or odovata), red (heart) hickory. 



The history of the name pignut as applied in literature to Hicoria 

 glabra has already- been traced.^ Doctor Sargent who has recognized-'' 

 the propriety of this name as applied to H. cordiformis, where it 

 seems to belong, has thrown additional light on this usage. One addi- 

 tional case might be added here. C. D. Mell, in his list of Pennsyl- 

 vania-German names of tree, give sauer hickory as the name for 

 pignut, referring this name to H. glabra. Of the Pennsylvania hick- 

 ories only the fruit of H. cordiformis could be described as sauer. 

 His pignut consequently should refer to cordiformis. 



Until recently the common name exclusively used in literature for 

 Quercus digitata (Q. falcata Mx. ) has been Spanish oak. This oak 

 and all of its forms seems to be known from Maryland, Ohio, and 

 Indiana to Florida and Texas as red oak.'^ Sometimes there is a dis- 

 tinctive designation to indicate site on which it grows as swamp red 

 oak for the variety leucophylla.

'Among some of the other most distiuet t'orms which have been referred to Hicoria glabra, 

 the so-called pignut, may be inentioned : Hicoria leiodermis n. c. (Cari/a leiodermi.i Sargent, 

 Bot. Gaz. 65: 239. 19i8) which is the common hickory of Louisiana, eastern Texas, and 

 Mississippi on banks of streams. It is related to H. glabra but has more numerous leaflets. 

 Its variety H. leiodermis callicnma n. c. (Garya var. Sarg. op. cit., p. 240) is a frequent 

 form of the preceding with thinner husk to the fruit. 



Hicoria iloriduna n. c. (Carya floridana Sarg., Trees and Shrubs 1: 193. 1911). Penin- 

 sular Florida. Related to H. glabra, but fruit ripens in midsummer. 



Hicoria buckleyi villosa n. c. {Hicoria glabra villosa Sarg., Silva 7: 167. 1895).
