p. 57? qui planta valde dubia. — Variat insuper vaginis subvillosis. 
3. Lindheimeri ; laminz basi pilis longis e tuberculis ortis dense 
barbatz. Spiculz sessiles 10 mm. long&. Reliqua pr&cedentis. 
4. pycnanthus ; lamin® glabr& ; articuli spicula sessili 3-plo brevio- 
res, unde spicule densissime imbricatz. Spicula sessilis 7—8 mm. 
longa, pedicellata basi glabra. 
Habitat subv. genuinus in Galloprovineise collibus saxosis raro. 
Vidi specimina a cl. Gandoger pr. Cannes loco dieto « la Californie » 
lecta, quæ spontanea esse declarat « nisi a quodam seminata. » Cl. A. 
Franchet (in Bull. Soe. bot. France, 31 (1884), p. 352) plantam in 
Gallia nullibi spontaneam esse contendit, suspicaturque, Gerardium, 
verum speciei auctorem, aut plantam cultam aut adventitiam ex 
America ortam descripsisse. Obstat huic opinioni, quod planta gallica, 
quamquam americana simillima, tamen nota supra allata, nimirum 
. eallo spiculz c? manifeste barbato plerumque ab americana recedit ; 
unicum specimen vidi in civ. Ohio lectum (in h. DC.), callo illo sub- 
distinete barbato. 
Subv. furcatus in America boreali-orientali a civ. Neo-Brunswick 
usque in Floridam ; in occidentem versus usque ad Texas, Colorado, 
septentrionem versus in Americam brittanicam ad fl. Saskatchewan, 
lacum Michigan et Huron, immo ex Hooker ad sinum Hudsonis 
usque pertinet; ubique fere communis est. Subv. Lindheimer:i in civ. 
Texas (Lindheimer 741); subv. pycnanthus in Texas (Vinzent dd et 
Neo-Mexico (Brandegee). 
Status abnormes : 1° rhachis more qui germanice dieitur

sessiles bitlorze, flore utroque 8, glumá floriferä (IV* et V*) aristatä, 
paleam fovente. Tales sunt plurim& speciminis Lindheimeri supra 
citati.
