668 LXX. UMBELLIFER.E. (C.B.Clarke.) [Hydrocotyle. 



VAR. 1. podantha, Molkenboer in PI. Jungh. 89 (sp.) ; pedicels | in. Miq. Fl. Ind. 

 Bat. i. pt. i. 732. Sikkim, Bhotan, Khasia, frequent. Peduncles sometimes 3 in. 

 Fruits ovoid, intermediate primary ridges 0. Keferred to H. podantha from the 

 description only ; Molkenboer relies partly on the leaves being setulose, but so 

 they are in typical H. javanica. H. laxiflora, DC. Prodr. iv. 61 ( = H. densiflora, DC. 

 Prodr. iv. 61), does not 'differ unless by the fruits being slightly less compressed. 



VAB. 2. Hookeri ; leaves very pentagonal little lobed, peduncles 6 in., fruit little 

 compressed yellowish shining with red glandular dots. Khasia, alt. 5000-6000 ft. ; 

 H.f. $ T. Leaves 1\ in. diam., sparingly setulose. Fruit somewhat pentagonal, the 

 immediate primary ridges -more, defined, nearly as in H. rotundifolia. This may be 

 a distinct species. 



2. H. burmanica, Kurz in Journ. As. Soc. 1871, pt. ii. 60, and 1877, 



pt. ii. 113 ; quite glabrous, leaves 5-lobed to the middle, lobes triangular acute 

 crenate, peduncles long ; pedicels f in., fruit moderately compressed somewhat 

 pentagonal. 



UPPER TENASSERIM ; alt. 3000-5000 ft. ; Brandis, Parish. 



Leaves l-2i in. diam. Peduncles 1-2| in., lower solitary leaf-opposed, upper 

 2-3-nate. Umbels many-flowered ; bracts minute. Fruit ^ in., broadly orbicular, 

 obscurely punctate not reticulate ; lateral primary ridges commissural, intermediate 

 appearing as slightly elevated angles; pericarp hard, thin. Very near H. javanica, 

 differing in its glabrousness, 5-gonous leaves, and less compressed "fruits. It may be 

 H. javanica (cf. Hiern in Oliv. Fl. Trap. Afr. iii. 4) when No. 1 must be called 

 H. hirsuta, Blume. 



3. H. conferta, Wight Ic. t. 1002 ; leaves cordate crenate subentire or 

 lobed to the middle, petiole laxly pubescent, umbels subsessile, fruit somewhat 

 compressed subpentagonal. 



SOUTH DECCAN; Pulney Mts., Wight; Nilgherry Mts., Gardner, Schmidt. 



Leaves 1-2^ in. diam., setulose. Umbels 5-15-flowered ; peduncle when visible 

 glabrous, any bracts obscure. Fruit ~$ in., orbicular, obscurely punctate, not reti- 

 culate ; lateral primary ridges commissural, intermediate, appearing as slightly 

 elevated angles ; pericarp hard, thin. From the size and hairiness of the leaves 

 this has been supposed near H. javanica, differing by its sessile clusters of fruit in 

 the axils ; but in the structure of its fruit it is exceedingly like H. rotundifolia 

 with wh|bh indeed it is mixed by Wight ; and from some forms of which it hardly 

 differs but by the larger more hairy leaves. 



4. H. rotundifolia, Roxl. Hort. Beng. 21, FL 2nd. ii. 38 ; leaves orbi- 

 cular-cordate subentire or lobed to the middle or lower, pedicels 0, fruit some- 

 what compressed pentagonal. Watt. Cat. 562; DC. Prodr. iv. 64; Wight Ic. 

 t. 564. H. nitidula, A. Richd. ; DC. Prodr. iv. 66 ; Hook. Ex. Fl. t. 29. H. 

 tenella, Don Prodr. 183 ; DC. I c. 64; W. $ A. Prodr. 366. H. ranunculoides, 

 Blume Bijd. 884 (fide Molkenboe?'). H. puncticulata, Miq. Fl. Ind. Bat. i. pt. 

 i. 733. H. Zollingeri, Molkenb. ; Miq. I. c. 733. H. perexigua, Hance in Walp.

NORTH-WEST HIMALAYA ; alt. 4000-7000 ft. BENGAL PLAIN, ascending to 4000 ft. 

 in SIKKIM and KHASIA, frequent. Mts. of MALABAR and CEYLON, Wight. DISTRIB. 

 Throughout Malaya. Guinea. 



Leaves \-\ in. diam., glabrous and shining or pubescent or subvillous on both sur- 

 faces. Peduncles glabrous, 0-f in., sometimes on the same specimen ; bracts obscure ; 

 umbels 10- 15 -flowered. Fruit ^ in., broadly orbicular, smooth, sometimes punctate ; 

 lateral primary ridges commissural (more prominent than in the three preceding 

 species), intermediate forming elevated angles ; pericarp hard, thin. Easily separated 

 from the three preceding species by the much smaller leaves. The multiplication of 

 names is chiefly due to the variability in the length of the peduncle, the specimens
