112 Morris: Revision of Species of Plantago 



20-50 mm. high, villous :. spikes thick, conspicuous on account of the 

 relatively large corollas, erect, ovate to short -cylindrical, 10-30 mm/ 

 by 5— 10 mm., villous at the base to pilous at the apex: bracts 

 rigid, herbaceous and scarious-sided, the lowest surpassing (by one 

 half-length) the flowers to the uppermost equalling the calyx, 

 linear-subulate, acute, 5-8 mm. long, villous : flowers perfect, 

 numerous : calyx pubescent to villous, its divisions herbaceous and 

 scarious-sided, dark-green or brozuu, spatulate-oblong, obtuse, 



4 mm. long : corolla with the tube less than one third surpassing 

 the calyx, its lobes strongly reflexed in fruit, twice the length of the 

 constricted throat, broadly ovate, obtuse, 3-5 mm. by 3 mm., white, 

 with a deep brown throat : stamens four, just exserted from the 

 throat : pyxis one third surpassing the calyx, oblong, truncate at 

 the apex, 4 mm. by 3 mm., circumscissile at the lower third : seeds 

 two, brown, narrowly oblong, -slightly constricted below the mid- 

 dle, finely pitted.

A relatively tall dark green annual, with an erect stem, glabrous 

 except the spikes and the upper part of the peduncles : leaves alter- 

 nate, erect, numerous, linear, truncate and callous at the apex, en- 

 tire, occasionally involute near the apex, tapered to the narrow 

 petiole having a semi-clasping base, 60-160 mm. by 3—4 mm., 

 sometimes narrower, j- 5 -nerved, glabrous or with a few hairs only : 

 peduncles axillary, slender at the base and gradually dilated to the 

 stout summit, solitary to several, surpassing the leaves, 100-300 

 mm. high, appressed pubescent : spikes many-flowered, conspicuous 

 on account of the large corollas, erect, long -cylindrical, 25—65 mm. by 

 6—8 mm., villous: bracts rigid, herbaceous and with scarious mar- 

 gins, equalling or shorter than the sepals, triangidar-lanceolate to 

 ovate, obtuse, 3 mm. by I mm., villous or less hairy : flowers per- 

 fect : calyx thick and rigid, pilous, its divisions herbaceous, dark 

 green or broivnish, narrowly obovate, rounded, 3 mm. long : corolla 

 lobes spreading and reflexed, the two laterals deflexed, triangular- 

 ovate, obtuse, 3 mm. by 2.5 mm., white; stamens four, long-ex- 

 serted : pyxis one third surpassing the calyx, ovate, rounded, 4 mm.
