I. PHRYMA L. 



A monotypic genus of eastern N. Am., eastern and central Asia. 



1. Phryma Leptostachya L. Lopseed. (I. F. f. 3377.) Puberulent; stem 

 somewhat 4-sided, sometimes constricted above the nodes, branched above, the 

 branches slender, elongated, divergent. Leaves ovale, acute or acuminate, coarsely 

 dentate, 5-15 cm. long, the lower petioled, the upper often nearly sessile; spikes 

 very narrow, 7— 15 cm. long; flowers about 6 mm. long, mostly opposite, distant, 

 borne on very short minutely 2-bracteolate pedicels, at first erect, soon spreading, 

 the calyx, after flowering, abruptly reflexed against the axis of the spike. In 

 woods and thickets, Can. to Minn., Fla. and Kans. June-Aug. 



Order 6. PLANTAGINALES. 

 Only the following family: 



Family 1. PLANTAGINACEAE Lindl.* 



Plantain Faintly. 



Herbs, with basal, or, in the caulescent species, opposite or alternate 

 leaves, and small perfect polygamous or monoecious flowers, bracteolate 

 in spikes or heads, or rarely solitary. Calyx 4-parted, inferior, peristent, 

 the segments imbricated. Corolla hypogynous, scarious or membranous, 

 mostly marcescent, 4-lobed. Stamens 4 or 2 (only 1 in an Andean 

 genus), inserted on the tube or throat of the corolla; filaments filiform, 

 exserted or included; anthers versatile, 2-celled, the sacs logitudinally 

 dehiscent. Ovary sessile, superior, 1-2-celled, or falsely 3-4-celled. 

 Style filiform, simple, mostly longitudinally stigmatic. Ovules i-several 

 in each cavity of the ovary, peltate, amphitropous. Fruit a pyxis, cir- 

 cumscissile at or below the middle, or an indehiscent nutlet. Seeds 

 i-several in each cavity of the fruit; endosperm fleshy; cotyledons nar- 

 row ; radicle short, mostly straight. Three genera and over 200 species, 

 of wide distribution. 



K lowers in spikes or heads; fruit a pyxis. i. PiantagV. 



Flowers monoecious, the staniinate solitary, peduncled, the pistillate sessile among the 



linear leaves ; fruit indehiscent. 2. Littorella. 



1. PLANTAGO L. (See Appendix.) 



Leafy-stemmed, short-stemmed or acaulescent herbs, with opposite, alternate 

 or basal leaves, bearing axillary or. terminal spikes or heads of small greenish or 

 purplish flowers (flowers solitary in a few exotic specie-). Calyx-segments equal, 

 or two of them larger. Corolla salverfbnn, the tube cylindric. or constricted at the 

 throat, the limb spreading in anthesis, erect, spreading or reflexed in fruit. 4-lobed 



or 4-parted. Stamens 4 or 2. Ovary 2-celled, or falsely 3-4-celled; ovules 



1 several in each cavity, bruit a membranous pyxis, mostly 2-celled. Seeds 



various, sometimes hollowed out on the inner side. [The Latin name.] Over 200
