length according tou age, commonly bent in different shapes, often like an 
S, adscendent, strict or procumbent, 6-60°™ high; thick, fleshy, fragile, 
like the whole plant, when young, tough and leathery when old. Leaf- 
blades varying from broadly lanceolate to linear, tapering at both ends, 
usually 5-ribbed, 2-15°™ long. o.5-2°™ wide, somewhat glaucescent; 
petioles 3—35°™ long, the length differing very much between the petioles 
of the same plant. The lowest part of the petiole is dilated, but only half 
as much as in A. Plantago, and with a narrow, scarious margin (A. Plan- 
tago has the lowest part of the petiole very much dilated and broadly 
scarious-margined). The inflorescence has generally a more rounded out- 
line and apex than that of A. Plantago, and some or all of the leaves reach 
higher than the top. (At the late fruiting season the inflorescence of one 
of the scapes will generally reach above the top of the longest leaf.) Pedi- 
cels verticillate in two to six rows, the shorter generally thicker than the 
others, horizontal (or sometimes drooping), forming secondary verticils, 
but seldom tertiary. each verticil subtended by three lanceolate, acuminate 
bracts. Petals 1-2™™ long, light rose-colored, with the yellow spot of 
the unguis comparatively much larger than in A. Plantago, 1.5 times 
longer than the sepals, the upper margin often more or less fimbriated. 
Sepals striate, with seven pairs of ‘‘nerves,” oval, with deeply rose-colored 
hyaline margins, often giving the predominant color to the flower. Stamens 
six, of the same length as the ovules. Styles numerous, bent outwards in 
a hook, shorter than the ovules. Nuts joined inwardly, and thus covering 
the center of the receptacle—The species is subdivided as follows: 
Var. pUMILUM Prahl, Kritische Flora 2:204. 1890.—A. Plantago arcu- 
atum minimum Buchenau, |. c. A. Plantago pumilum Notte in Sonder, 
Flora Hamb. 210. 1851.—With usually a single verticil (more seldom two). 
Var. lanceolatum (Buchenau) Lunell.—A. Janceolatum et A. Plantago 
lanceolatum auct. div.—Leaf-blade elliptic to lanceolate (seldom linear- 
lanceolate), acute, tapering at both ends. This is the usual terrestrial or 
emersed form, growing under exactly the same conditions as A. Plantago, 
and mixed with it. (Fig. 1.)
