26. APOCYNUltt, Linn. 



Erect herbs or undershrubs. Leaves opposite. Cymes terminal and lateral ; 

 flowers small. Calyx 5-fid, eglandular within ; lobes acute. Corolla campanu- 

 late, 5-fid, with 6 processes between the stamens ; lobes overlapping to the 

 right. Stamens near the base of the corolla, included ; anthers sagittate, acute, 

 conniving and adnate to the stigma, cells with basal spurs. Disc fleshy, 5-lobed. 

 Carpels 2, distinct, many-ovuled, half sunk in the disc, to which they are adnate 

 by the back ; style short or 0, stigma subglobose, tip 2-lobed. Follicles slender. 

 Seeds small, oblong, with a terminal caducous coma, albumen scanty, cotyle- 

 dons flat. DISTEIB. Species 5, of the north temp. zone. 



A. venetum, Ztnn.; A. DC. Prodr. viii. 400; Boiss. Fl. Orient, iv. 48. 



WESTERN TIBET ; Shayuk valley, alt. 8000 ft. (without flower or fruit), Thomson.

 petiole very short. Cymes small, erect, subcorymbose ; bracts subulate. Flowers 

 erect, in. diam., purplish, puberulous. Carpels with pubescent tips. Follicles 4 in.
