69. PLANTAGINACE^I, PLANTAIN FAMILY. 



Consists almost entirely of the very familiar weedy genus 



1. PLANTAGO, PLANTAIN, RIBGRASS. (The old Latin name.) 

 Flowers in a spike, on a naked scape, small, whitish. Sepals 4 (or rarely 3 

 from two of them growing together), imbricated, persistent. Corolla short 

 salver-form, thin and membranaceous, usually becoming scarious and dry, or 

 withering on the pod ; lobes 4. Stamens 4 (or rarely 2) borne on the tube of 

 the corolla : filaments usually lengthening suddenly at flowering time and 

 hanging (as in Grasses), bearing the 2-celled anthers. Style and long hairy 

 stigma single and thread-like. Ovary 2-celled. Pod 2-celled, a pyxis, the top 

 falling off as a lid, and the partition then falling out along with the 2 or more 

 seeds. Leaves parallel-ribbed, all from the ground. The following are the 

 common species : fl. summer. 



1. Flowers all alike and perfect, in each the style protruded a day or two lief ore 

 the anthers open or are hung out : lobes of corolla remaining wide open. 



P. major, COMMON PLANTAIN, in yards, &c. Usually smooth or smooth- 

 ish, with ovate or oval 5-7-ribbed leaves, a slender spike, and 7-16-seeded 

 pod. }Z 



P. lanceolata, RIBGRASS, RIPPLEGRASS, or ENGLISH PLANTAIN. Nat.

P. maritima, SEASIDE P. Salt-marshes N. E. ; smooth, with linear thick

 corolla, the other with minute short stamens, and corolla closing permanently 

 over the pod.
