 Flowers in a naked raceme, rather distant, on pedicels about 2 hnes long, which are furnished 

 with a short subulate bract at the base. Calyx-segincnis lanceolate. Corolla small, pale 

 blue ; the spur descending, straight and very slender. Capsule roundish-ovoid, as long as

[ In honor of the late Zaccheus Collins of Philadelphia, an accurate Iiotanist, and promoter of natural science.] 



Calyx 5-cleft. Corolla personate : upper lip 2-cleft ; the lower 3-cleft ; the middle lobe 

 saccate-carinate, and surrounding the stamens. Capsule globose, membranaceous ; the 

 dissepiment early breaking away from the valves. Seeds usually 2 (sometimes by abortion 

 only one) in each cell, obliquely superimposed, umbilicate. — Annual herbs, with opposite 

 or ternate leaves, and axillary one-flowered opposite or verticillate peduncles. Flowers 

 ornamental. 



1. CoLLiNSiA VERNA, Nutt. Early Particolored Collinsia. 



Assurgent, nearly smooth ; leaves remotely and rather obtusely serrate ; the radical oblong 

 or cordate and petiolate ; cauline opposite, ovate-oblong, sessile or clasping , the uppermost 

 ternate. — Nutt. I. c. ; Torr. compend. p. 241 ; Sweet, Brit. fl. gard. t. 220 ; Beck, hot.

Stem 6 - 12 inches high, slightly pubescent, at length branching. Leaves about an inch 

 long, mostly obtuse ; the lower and radical ones on petioles which are half an inch or more 

 in length. Pedicels pubescent, about an inch long. Calyx-segments lanceolate, acute, minute. 

 Corolla particolored : the upper lip erect, deeply 2-cleft ; the lobes broadly obovate, yellowish 

 white : lower lip 3-cleft ; the middle lobe saccate or cucullate, and keeled on the underside, 

 enclosing the declinate stamens ; lateral lobes blue. Stamens didynamous, approximated : 

 filaments slighllj' pubescent : anthers cordate-reniform ; the cells opening along the margin, at 

 length confluent. Abortive stamen in the form of a short spur at the base of the corolla. Ovary 

 ovoid, 2-cellcd ; the dissepiment placentiferous. Ovules 2 in each cell, one obliquely above 

 the other : style almost capillary, included : stigma minute, 2-cleft. Capsule 2-valved ; the 

 valves 2-cleft, early separating from the dissepiment. Seeds oblong, obtuse at each end, concave 

 on the face. Embryo straight, in the axis of firm albumen : coiyledons flat and foliaceous.
