SECTION IV 

 WHITE TO GREEN AND BROWN FLOWERS 



RICHARDSON'S PONDWEED 



Potamogeton Richardsonii. Pondweed Family 



A marsh herb. Stems: slender, much branched. Leaves: obtuse to 

 acute, curved inward at the apex, broadly cordate and clasping at the 

 base. Flowers: small, spicate, green or rarely reddish. Fruit: drupe- 

 lets, obliquely obovoid, obscurely three-carinate on the back, the face 

 curved outwardly towards the top. 



This Pondweed, which flourishes in lakes and streams, 

 frequently flowers and fruits under water; its large leaves, 

 heart-shaped at the base, being practically all submerged. 



Potamogeton filiformis, or Filiform Pondweed, has nu- 

 merous very narrow leaves, and flowers which grow in tiny 

 whorls near the top of the slender stems. 



GLUTINOUS ASPHODEL 



Tofieldia glutinosa. Lily Family 



Stems: viscid-pubescent with black glands, bearing two to four leaves 

 near the base. Leaves: basal ones tufted. Flowers: terminal racemes 

 oblong, the upper flowers opening first, becoming longer in fruit; invo- 

 lucral bracts minute, united at the apices, borne just below the flower; 

 perianth-segments oblong, obtuse, membranous. Fruit: seeds tailed at 

 each end. 



A traveller cannot pick the long spikes of tiny white blos- 

 soms which belong to this plant without at once recognizing 

 its name by the exceedingly sticky and hairy nature of the 

 stems. The Latin designation glutinosa exactly describes
