This appears to me as to Engelmann a very distinct species, but the sectional character 

 derived by Engelmann from the deeply-lobed concave stigma seems to have been an excep- 

 tiouaUy abnormal state in the flower examined. In other llowcrs I find the stigma larger 

 than in most species, but not very distinctly lobed. 



Order LXXXII. SOLANE^. 



Flowers regular or nearly so. Calyx free, usually with 5, rarely with 4, 

 6 or 10 teeth lobes or segments. Corolla with 5 or rarely with 4 teeth or 

 lobes, iudupllcate-plicate or rarely imbricate in the bud. Stamens as mniiy 

 as lobes of the corolla and alternate with them ; anthers various, usually 2- ^ 

 celled. Ovary superior, 2-cel!ed or rarely spuriously 4-ccllcd or abnormally 

 3- or more-celled ; style simple, terminal, with an entire or lobed stigma. 

 Trult an indehisceut berry or rarely a capsule, with several seeds. Embryo 

 usually curved or spiral, surrounding a fleshy albumen, rarely straight in the 

 centre of the albumen.— Herbs shrubs or soft-w^ooded trees!^ Leaves alter- 

 nate, without stipules. Flowers solitary or in centrifugal cymes or unilateral 

 racemes, usually at first terminal but becoming lateral by the elongation of 

 the shoot, rarely axillary, the cymes or racemes usually without bracts, and 

 no bracteoles on the pedicels. 



A numerous Order in the tropical an<l warmer regions of the globe, and more especially 

 S. America, with a comparatively few species strayin^g into more temperate districts both in 

 the northern and the southern hemisphere. Of the seven genera here enumerated, fonr have 

 nearly the range of the Order; one is a tropical weed spread from America; one has a 

 single Australian representative of an otherwise S. American genns ; and one only is en- 

 demic. The Order is closely connected with Scrophularinew, being technically separiited by 

 the more regular flower, with the stamens and corolla isomerons. On the other hand, it is 

 allied to Hydrophyllacere through Ilfjdrolea, which differs chiefly in its divided style ana 

 small embryo; and yet nearer to Polcmoniaceaj, an Order scarcely distinguished fro"i^"" 

 ianepe except by the almost constant tricarpellary ovary and contorted fcstivalion of the 

 corolla ; it is unrepresented in Australia, eicepting occasionally by a N.W. American M- 

 fomta or other annual escaped from a garden.
