giebt an ein Stamen weit liinger als die iibrio-en sjesehen zu 

 haben (iihnliche Liingendifferenz ist in andern Arten 

 normal)." I have examined Moquin-Tandon's* statement 

 and find that it is : " J'ai decouvert, pres de Toulouse, un in- 

 dividu de Solanum Dulcamara, dans lequel toutes les fleurs 

 superieurs offraient tantot deux, tantot trois etamines beau- 

 coup plus longues et plus grosses que les autres." In a foot- 

 note he then gives 8. tridynarnum (Poir) and 8. Amazonium 

 (Bellend) as producing three elongated stamens and 8. ves- 

 pertilio (H.Kew) and >iS'. cornuium (Juss.) as those in which 

 " uneetamine seulement acquiert une taille double du volume 

 habituel." 



The citing as an abnormality of the production of one 

 stamen longer than the others in 8. cornutum Lam. is 

 evidently an error due to an oversight on the part of Dr. 

 Penzig. The " 8. cornutum (Juss.) " to which Moquin- 

 Tandon refers is apparently the 8. cornutum described by 

 Juss.jf which is 8. cornutum Lam. 8. cornuticm Lam. is 

 clearly one of the species with produced stamens, according 

 to the description given by Dunal in his monograph, and 

 the original description of Lamarck. J 8. corniLtum (Hort. 

 Monsp.) according to Dunal § equals 8. rosfratum Dun. Under 

 8. Dulcamara L. Penzig says: " Im Androeceum beobachtet 

 man bisweilen, dass zwei oder drei Stamina liinger sind als die 

 iibrigen," but does not refer to the literature, so that the 

 observation may be one of his own. 



In one flower of several 



taken from a plant of 8. ni- 

 — gru7n near St. Louis, Mo., 



one of the stamens was notice- 



SoLA^uM TUBEROSUM. -Todd, ^bly longcr than the others, 



the increased length being 

 partly in the filament and partly in the anther.
