 « Flowers in rather hose clusters, mostly sh/rt-pedicelled, the scaly bracts few and 

 scattered: calyx 4 - 5<lefi. 

 ■>- Corolla with cylindricul tubf, in fruit covenng the top of the pod. 

 C. tenuifldra. On shrubs and tall herbs from N. Jersey W. & S in 

 swamps : pale ; tube of the corolla twice the length of its ovate acute spreadine 

 lobes and of the ovate blunt calyx-lobes. 



^■■, ™fl^^^- O" shrubs and tall herbs in prairies and barrens W. & S. ■ 

 corolla fleshy, mostly 4-eleft, its tube no longer than the ovate acutish crcnulate 

 erect or mflexed lobes of the corolla and the acute keeled calyx-lobes. 



C. decora. Wet prairies S. W. : with larger flowers, the corolla broartlv 

 bell-shaped, its 5 lobes lance-ovate and acute. 



■*-■*- Corolla bell-shaped, remaining at the base of the ripe pod. 



C. arv6nsis. On low herbs, in fields and barrens from New York to 111. 

 & S. VV. : flowers earliest (June, July) and smallest ; tube of corolla shorter than 

 its 5 lanceolate pointed spreading lobes, much longer than the stamens. 



C. ehloroci.rpa. On low herbs, in wet soil, from Delaware W. & S.W. : 

 orange-colored ; open bell-shaped corolla with lobes about the length of the 

 mostly 4 acute lobes and the stamens ; pod large, depressed, greeniish-yellow. 



C. Gronbvii. The commonest E. &. W. and the only one N. E. ; on coarse 

 herbs and low shrubs in wet places ; bell-shaped corolla with ' tube usually 

 longer than its 5 (rarely 4) ovate blunt spreading lobes ; its internal scales 

 large and copiously fringed. 



* * Flowers sessile in compact mostly cmitinwous clusters, making large bunches or 



close matted coils, when old resembling pieces of rope twisted around the stems 



of coarse herbs or shrubs : calyx of separate sepals surrounded by similar 



crowded bracts : remains of the corolla borne on the top of the ripe pod. 



C. comp^ta. On shrubs, from N. York S. & W. . bracts (3 - 5) and 



sepals round and appressed ; tube of corolla cylindrical. 



C. glomerdita. On Golden rods and other coarse Compositse, from Ohio 

 W. & S. W. : the numerous oblong scarious bracts closely imbricated with 

 recurving tips ; sepals similar, shorter than the cylindraceous tube of the corolla 



84. SOLANACE^, NIGHTSHADE FAMILT. 



Plants with rank-scented herbage (this and the fruit more com- 

 monlj narcotic-poisonous, colorless juice), alternate leaves (but ai)t 

 to be in pairs and unequal), regular flowers with the parts usually 

 in fives, but the ovary mostly 2-eelled, the many-seeded placentas 

 in the axis. The seeds have a slender usually curved embryo in 

 fleshy albumen. (Lessons, p. 23, fig. 50, 51.) The order runs on 

 the one hand into Scrophulariaceae, which a few species approach 

 in a somewhat irregular corolla, but their stamens are as many ns 

 the lobes. On the other hand the Nolana group is appended, which 

 differs from all in its separate ovaries around a common style.
