Caryophyllaceæ. 329 



Denmark. Trioecism and gynomonoecism ; protandry. 

 The scales at the throat consist of two low protuberances 

 with corresponding shallow depressions on the dorsal side. 

 Zygomorphy is often distinctly seen, the stamens and 

 styles being bent downwards in the lower part of the flower; 

 the flower is what Del pin о calls zygomorphic of the 1st 

 degree. 



^: Highly protandrous, the stamens appear gradually 

 not exactly in two sets. The stamens project far out. 



в are almost equal to g in size; they are hardly common. 



? < ^. Diameter of corolla 13^ — 14 mm, in ^ 15 — 18 mm 

 (the corolla grows during the flowering period), but other- 

 wise the difference is but slight. In both flowers the calyx is 

 12 — 13 mm in length, the corolla-tube in ? 9 — Ю^/г mm, 

 in У 11 mm; petals in $ 13 — 14 — 16 mm, in ^ 14—16^/2 mm, 

 the limb in $ 4 — 5 mm, in ^ 5^2 т^^^- The ovary is З^/г — 

 5 mm in length in both ; and the thickness and the length 

 of the style are the same in both. Nor can 1 see any differ- 

 ence as regards the ovules; there are about 12 in each row, 

 both in ^ and in $. The calyx-stamens in $ are often remark- 

 ably long, viz. 4^2 — Ö— 672 mm in length, so that they 

 project far above the ovary, and they have distinctly marked- 

 off, dorsified anthers; the length may diminish to 2 — 2i/2mm. 

 The cor.-st. are as usual somewhat smaller. The anthers are 



instance with regard to the involution of the petals (those that 

 become involute in the evening he calls '"meteoric corollas"); 

 and with regard to protandry, direct or indirect pollination (e. g. 

 self-pollination and crossing) ; and about movements before, under 

 and after flowering, etc. In one place he writes as follows: — 

 "Du reste, on peut croire qu'en observant les divers Silène sous 

 ce point de vue, on y découvrirait d'autres arrangements qu'on 

 ne soupçonne point encore, et qui donneraient une idée bien plus 

 grande de la richesse et de la variété que le créateur à mises dans 

 ses ouvrages, que ne peuvent le faire les differences de feuilles 

 ou d'inflorescences".
