Leaves glabrous shining: mostly uneqvial in each pair, the larger -i-S" long, oblong- 

 oblanceolate acuminate or caudate, rarely obovate, sec. n. fine, 5-6, petiole •25--4",

 A large shrub or small tree with somewhat distichously spreading 

 subsessile ovate to elliptic-oblong leaves 6-12" by l"5-5", strongly 

 nerved beneath and terminal corymbose cymes 3-6" wide of sweet- 

 scented white flowers 'TS-l'S" diam. Follicles slender divaricate 6-9" 

 (16", F.B.I.) long by about '16" broad. Seeds (Indra-jao, Inderjao, 

 ff.) linear- oblong, "5" long, with a long brown coma. 



Very common in all districts. Sometimes sub-gregarious. Frequent on the 

 Khurda laterite, but usually prefers damp localities. Fl. May- July. Fr. Dec- 

 Feb. Deciduous Feb.-April. It flowers on the new shoots. 



Bark thick smooth. Blaze brownish exuding latex from the layer next the wood. 

 Twigs and leaves glabrous, pubescent or tomentose. L. with a rounded apex or

 twig are usually broadly elliptic and only 3" long, sec. n. 8-13. Sep. "l". Cor.- 

 tube "4" pubescent, petals •5--G" or longer. 



The bark and seeds are an excellent cure for chronic dysentery. A case in

 distasteful to cattle and goats.

Shrubs or undershrubs with 3— i-nately whorled, rarely opposite

 sometimes sub-irregular, throat usually densely hairy within and
