Macbride — Certain Borraginaceae 43 
Species representing perfectly the generic characters and nearest 
to A. floribunda, from which it may be distinguished by its lack of 
spreading pubescence, its greener hue, its long narrow leaves and 
the much longer fruiting calyx. In A. floribunda the mature calyx 
is rarely 5 mm. long. A. durangensis comes the nearest to having 
smooth nutlets of any of the species, their surfaces being very 
slightly if at all roughened.

Greene founded his species on three specimens in which the ap- 
pressed strigose hairs that characterize C. leiocarpa are almost en- 
tirely replaced by a hispid spreading pubescence. The flowers, too, 
are slightly larger. Since then, however, specimens have been 
found which exhibit these characters in varying degrees. A specific 
instance is Mr. Heller’s number 8403, the type of his C. pumila. 
He distinguishes it (1. ¢.) from Greene’s species by its ‘ smaller 
corolla and smaller calyx, the segments not ‘long-attenuate’.’’ One 
has only to examine a few specimens in order to become convinced 
that such characters are too variable to possess any specific value. 
In Muhlenbergia, ii. 315 (1907) he refers to C. pumila his number 
8588 and remarks: ‘‘ Mrs. Brandegee considers this a mere state 
of C. leiocarpa but two plants differing so in habitat and appearance 
cannot possibly be the same.” Unfortunately this specimen is dis- 
tinctly strigose-canescent as well as hispid. Altogether it seems 
best to regard these plants which have the pubescence, at least in 
part, hispid-spreading as representing a recognizable variety.
