PHACELIA BIPINNATIFIDA. 
BIPINNATE PHACELIA. 
NATURAL ORDER, HYDROPHYLLACE®. 
PHACELIA BIPINNATIFIDA, Michaux.—A foot or more high from a slender biennial root, 
erect, paniculately branched, hirsute-pubescent and above mostly viscid and glandular: 
leaves slender-petioled, green and thin, pinnately three to seven-divided; the divisions 
ovate or oblong-ovate, acute, coarsely and irregularly incised or pinnatifid; the lower 
short-petiolulate and the uppermost confluent: racemes loose, seven to twenty-flowered: 
pedicels spreading or in fruit recurved: calyx-lobes linear, loose, longer than the 
globular capsule: corolla rotate-campanulate, violet-blue, over half an iach in diameter, 
with rather short rounded lobes and very conspicuous internal appendages: stamens 
(bearded) and style usually more or less exserted. (Gray’s Synoptica’ Flora of North 
America. See also Gray’s Manual of the Botany of the Northern United States ; Chap- 
man’s Flora of the Southern United States ; and Wood's Class-Book of Botany.) 
IN Dr. Gray's recent “Synoptical Flora of North 
i America,” from which we have taken our botanical 
description, fifty-five Phaceleas are described; and yet less than 
a hundred years ago not one was known. The first knowl- 
edge of them seems to have been gained from Commerson’s 
celebrated voyage, when one which we now know as Phacelia 
circinata was found in the Straits of Magellan. It was at that 
time thought to be a Heliotrope, and Martin Vahl, a Danish 
botanist, and one of the most celebrated of that time, named it 
fFlehiotropium pinnatum, under which it is to be searched for in 
the earlier writings of Willdenow and of some others. But 
Jussieu, the well-known botanist of the end of the last century, 
in his “Genera Plantarum” published in 1789, made a new 
genus of it, Phacelia, which name it still bears. That particular 
species has the flowers growing in dense bunches or fascicles, 
and this suggested the name, pfhakclos being Greek for a 
fasicuius or bunch. This original species is very remarkable
