 cites Dunal in the Synopsis. In his description the lobes of 

 the corolla are given as equal, anthers as " unequal ( ?),'' 

 and stigma subcapitate. /S. citrullifolium A. Br. (= S. het- 

 erodoxum Dun.) is described f as follows: "Corolla ampla

 productissima curvata. — Semina Texana Lindhehneriana sub 

 nomine Nycterii violacei communicavit Engelmann. ' ' Regel % 

 describes S. citrullifolium. Both his descriptions and the 

 figures, pi. 112 (?), represent the lower, fifth, stamen as 

 about twice the length of the others. In his monograph in 

 De Candolle's Prodromus Dunal does not cite 8. citrulU folium,^ 

 but in the Addenda et Corrigenda at the end of the work 

 Alphonse De Candolle gives the description of this species 

 and regards it as an insufficiently known species belonging 

 with their species 759-766. § 8. heterodoxum is described 

 in detail: "Antherae * * * 4 subaequales, 2 lin. longae

 large, violet, an inch in diameter. The last three species U 

 belong to a remarkable group (Cryptocarpum, Dunal) which 

 Nuttal regarded as a proper genus (Androcera)." As the next

1 He evidently means this, the preceding, and the following species^ 

 rather than this and the two preceding or the last three species of the list, 

 since the latter arrangements which are the literal interpretation of his 

 statement, would include S. elaeagnifoliura Cav. or S. verbascifolium.
