being in other respects very uniform. Some of the hill examples have shining 

 glabrous subserrate levies, the peduncles in. ; other plains' examples closely pro- 

 cumbent on mud are villous with sessile umbels. H. kirta, R. Br. differs (if at all) 

 by its laxly hairy peduncles : see Benth. Fl. Austral, iii. 340, as to Var. pusttla only. 

 H. sibthorpwides, Lamk. ; DC. Prodr. I. c. 66, which extends throughout South- 

 Eastern Asia and Japan, only differs (from the form nitidula) by the rather larger 

 leaves and longer peduncles.

Throughout INDIA, alt. 0-2000 ft. ; from the HIMALAYA to CEYLON and MALACCA ; 

 frequent. DISTRIB. Tropical and subtropical regions. 



Leaves -2^ in. diam., usually glabrous or nearly so ; petiole pubescent or glabrous. 

 Peduncles about \ in., often 2-3-nate, laxly pubescent or glabrous; bracts - in., 

 not scattered among the pedicels (as in Eu- Hydrocotyle and in Araliacece}. Fruit 

 - in. Carpels oblong, subcylindric, curved, slightly compressed, much longer than 

 broad, reticulate-rugose, often crowned by the subpersistent petals, each with 9 cur- 

 vilinear subsimilar ridges, and 2 within the commissure ; pericarp thickened, 

 woody, white. Seed compressed laterally. In this species it seems to be the endocarp 

 that is so greatly thickened, and that is adnate to the exocarp, thus invalidating one 

 of the most uniform distinctions between Umbelliferce and Araliacece (see Gen. PI. 

 i. 861). 



2. ERYNGIUIYI, Linn. 



Spinescent, glabrous, erect, perennial herbs (the Indian species). Leaves 

 spinous-toothed, entire lobed or dissected. Flowers in simple heads, each brac- 

 teolate; bracts stellate, spinulose (in Indian species). Calyx-tube covered with 

 ascending hyaline scales ; teeth rigid, acute. Petals white, narrow, erect, 

 emarginate, scarcely imbricate. Fruit ellipsoid, nearly cylindric : carpels dor- 

 sally subcompressed, subconcave on the inner face ; primary ridges obtuse not 

 prominent, secondary ; vittae in the primary ridges inconspicuous or 0, with 

 some very slender scattered in the endocarp : carpophore 0. Seed semi-terete, 

 dorsally subcompressed, subconcave on the inner face. DISTRIB. Species 100, 

 temperate and tropical ; plentiful in Western Asia.

Stems 2-3 ft., erect, undivided below, corymbose and often bluish above. Radical 

 leaves 5 by If in., petiole 2-6 in.; lower cauline often similar smaller with shorter 

 petioles, but more often subsessile, elliptic, acute, undivided, serrate or subspinulose. 

 Bracts 5-6, 1 in., linear, with a few spines on the margins, sometimes short exterior 

 spines alternating with them ; bracteoles linear, spinulose, simple, exceeding the 

 flowers; a few (in the outermost row but one) sometimes spinous, subtrifid.
