§79. 



Salicinece. — Saliie stipularis, Sm. : branches of the stigma 

 right when dried up. 



§80. 



Nyctaginecs, — Bugainvillea spectabilis : withering flowers right. 

 Pisonia grandis, R. Br. ; a plant which I have never seen my- 

 self, but which is represented with right-wound styles in Endli- 

 cher's ' Iconographia ' (Vindob. 1838). 



§81. 



Gyrocarpece, — According to Nees v. Esenbeck, — Wallich, 

 Plantae Asiaticae rariores, ii. 68, — the cotyledons are wound 

 heliacally round the two-leaved plumule : I have had no oppor- 

 tunity of observing for myself. The direction of the winding is 

 unknown. 



§82. 



Santalacea. — Thesium ramosum, Hayne : stem-leaves left. 

 The stem-leaves of Thesium pratense, Ehrh., and Th, ebractea- 

 turn, Hayne, are also often wound, but not in any definite direc- 

 tion. Santalum cognatum, Miquel : petioles left, not quite \. 



§83.

 the lefl. The same in Daphne olecefolia, Lam.

 carpa, R. Br. ; H, latifolia, Loddig. ; Protea longiflora, Lam. ; 

 Pr. inflexa, Willd. ; almost all species of Leucadendrum, e. g. L. 

 ascendens, R. Br. ; L, diversifolium, R. Br. ; L. tortum, R. Br. ; 

 L, cuspidatum, KL, &c. : stem-leaves left ; in Hakea latifolia, 

 Loddig., it is the attenuated points of the leaves which wind, in 

 the rest the lower parts of the leaves which run down into an 

 imperfect petiole. Conospermum capitatum, R. Br. : the narrow 

 stem-leaves, nearly a foot long, right. Conospermum teretifolium, 

 R. Br. : petals in the bud twisted like a cord to the left. For 

 the winding style of Protea longiflora, see § 43.
