3. COLDENIAL. 



Low prostrate or spreading herbs or herb-like plants, some species suffrutes- 

 cent, all hoary-pubescent and often hispid, the small pale flowers sessile and usually 

 clustered in the forks or at the ends of the branches and subtended by a circle of 

 leaves. Leaves small, petioled, with veins usually conspicuous. Calyx (in ours) 

 5-parted into slender segments. Corolla short-funnelform or nearly salverform, 

 1 to 2 times as long as the calyx, the short lobes broad and rounded. Stamens 

 included. Style 2-cleft or -parted. Ovary entire or 4-lobed, 4-celled. Fruit sepa- 

 rating at maturity into 4 one-seeded nutlets, or by abortion fewer. — Species 15, 

 all continents except Europe. (Dr. Cadwallader Colden, Colonial Lieutenant- 

 Governor of New York, a correspondent of Linnaeus. ) 



Stems dichotomously branched; leaves conspicuously impressed -veined, the longer petioles % to 

 IV2 times as long as the blade; corolla-tube bearing scales or plates; style cleft % or 

 more. 

 Leaf -blades ovate to rotund or rhombic, grayish-strigose and somevfhat hispid or hirsute, with 

 2 or 3 pairs of veins. 



Leaf -margins entire; stems from an annual root 1. C nuttallii. 



Leaf-margins sinuate ; stems arising from a perpendicular perennial root..2. C. brevicalyx. 

 Leaf -blades mostly obovate, furrowed with 5 or 6 pairs of veins, the pubescence felty but not 



hispid or hirsute; stems arising from perennial root-stocks 3. C. palmeri. 



Stems diffusely branched; leaves not obviously veined, the petioles almost none or only 14, to % 

 as long as the blade ; corolla-tube destitute of scales or plates ; style shortly cleft at apex ; 

 stems from a perennial root 4. C. canesecns. 



1. C. nuttallii Hook. Stems few or several from an annual root, dichotomously 

 branched, forming prostrate mats 4 to 13 inches across ; herbage thinly hirsute, the 

 leaves also gray-strigose ; leaf-blades ovate to rotund, revolute-margiued, with 2 

 or 3 pairs of impressed veins, 2 to 4 lines long, the petioles often longer ; flowers 

 densely clustered in the forks and at the ends of the branches, subtended by a circle 

 of leaves ; calyx-lobes linear, hispid and with 1 to 3 setae at tip, equaling the corolla- 

 tube; corolla pink or whitish, l^o lines long, 1 to 1^/4 lines broad, bearing 5 short 

 scales near the base of the tube, the scales triangular, somewhat sac-like, adnate 

 on the sides and open below ; filaments shorter than the anthers, inserted in upper 

 part of the corolla-tube ; style divided % or %; nutlets oblong-ovate, polished, the 

 scar linear.
