302 Notes on Indian Botany. 



cral scales : pappus wanting [unless the elongated points of 

 the involucrum be considered such.] Herbaceous diffuse 

 plants : leaves alternate dilated amplexicaul at the origin 

 of the flowers : flowers sessile, surrounded by 2-3-orbicular 

 leaves and some small bracts forming the general involucrum, 

 pale violet or white opening from the centre towards the 

 circumference. [This genus seems badly placed here, having 

 apparently no affinity with the plants among which it is 

 stationed.] 



Sub-tribe Eclypte^e. Capitula heterogamous, flowers of 

 the ray female, except Cryphiospermum ligulate ; of the 

 disk hermaphrodite: anthers ecaudate. Receptacle paleace- 

 ous : pappus either none or aristate, never setaceous ; leaves 

 opposite. 



37- Eclipta, (Lin. D. C. 5-489). Capitula many flowered, 

 heterogamous, of the ray 1 -series female, shortly ligulate; 

 of the disk tubular 4-toothed : achsenia of the ray triangular, 

 of the disk compressed, tuberculated on the sides, scarcely 

 apiculate. Rough herbaceous plants with opposite leaves and 

 solitary axillary peduncles; involucrum 2-series, scales 10-12; 

 receptacle flat, covered with lanceolate palese ; flowers white, 

 juice employed to dye black. 



38. Blainvillea, (Cass. D. C. 5-492). Capitula hetero- 

 gamous, flowers of the ray few, 1 -series, expanding into a 

 broad, short, irregularly 3-cleft ligula; of the disk tubular 

 5-cleft : style of the disk included : achaenia of the ray tri- 

 quatrous, bearing 3-rigid persistent ciliate bristles ; of the 

 disk compressed biaristate. Herbaceous plants with opposite 

 triplinerved leaves : peduncles axillary monocephalous : in- 

 volucrum cylindrical, 1 -2-series, exterior ones foliacious : 

 receptacle narrow, palese embracing the flowers concave, 

 membranaceous ; flowers white.
