XIX. DIPCVSIS (from tits, dis, twice, and jroirtc, posts, a

 bellule, and only one fertile). D. C. coll. mem. 5. p. 33. t. 3.

LIN. SYST. Pentandria, Digynia. Margin of calyx bluntly 

 5-toothed. Petals oval, flat, entire. Styles short. Fruit orbi- 

 cular, biscutate; mericarps compressed from the back, joined with 

 the narrow commissure, and therefore constituting 2 parallel 

 disks ; dorsal rib filiform, 2 lateral ones hidden, and the middle 

 ones girding the disk ; vittae wanting ; furrows between the ribs 

 broad and flat. Stemless glabrous herbs, natives of Chili and 

 Brazil. Leaves all radical, petiolate, ternate : leaflets wedge- 

 shaped, toothed or cut at the apex ; the lateral segments some- 

 times 2-parted. Scapes longer than the leaves. Umbels com- 

 pound, 6-8-rayed ; peduncles much longer than the involucrum, 

 which is 4-5-leaved. Umbellules 3-flowered, middle flower fer- 

 tile, lateral 2 male ; hence the generic name. Flowers white. 

 The fruit is like that of Mulinum, and the inflorescence that of 

 Petdgnia. 



1 D. SANICULJEPOLIA (D. C. 1. c.) roots fusiform ; leaves ter- 

 nate : leaflets wedge-shaped, tridentate : lateral leaflets sometimes 

 2-parted; umbels 6-8-rayed. %. F. Native of Monte Video.

 ous, globose ; leaves many-parted. 7(..F. Native of Chili, in 

 sterile pastures, at Rancagua. Bunium Bulbocastanum ? Bertero, 

 herb. Herb glabrous. Root black on the outside, nearly like 

 that of Carum denudatum or C. Bulbocastanum. Umbels com- 

 pound, 3-4-rayed, surrounded by a 3-5-leaved involucrum ; um- 

 bellules 3-flowered. Fruit parallelly biscutate.

LIN. SYST. Pentandria, Digynia. Limb of calyx 5-toothed. 

 Petals elliptic, entire, acutish, with a straight apex. Fruit ovate, 

 much compressed at the raphe, flat, and compressed from the back 

 on both sides ; mericarps flat, without any vittae ; ribs 5, very 

 slender, equal, 3 intermediate ones on the back, and the 2 lateral 

 ones seated in the commissure, which is flat. Seed flat. A 

 South American branched erect herb, glabrous in every part, 

 except on the petioles, which are ciliated along the sheaths, and 

 ornamented with a collar of hairs under the origin of the limb. 

 Leaves cordate, toothed, acute. Umbels rather compound, pro- 

 liferous. Involucra composed of many leaves. Flowers white 

 on long pedicels. 



1 S. PANICULA'TA (Jacq. 1. c. and icon. rar. 3. t. 350.) 0. S. 

 Native of South America, in Trinidad, and the Spanish Main, as 

 well as of Peru. Hydrocotyle spananthe, Willd. spec. 1. p. 

 1363. Phellandrium ciliatum, Willd. herb. Perhaps the Peru- 

 vian plant is the same as that from the Spanish Main, but it is 

 much smaller and hardly panicled. 



Panicled Spananthe. Fl. July, Aug. Clt. 1795. PI. 1 to 2-ft. 



Cult. The seeds of this plant should be raised on a hot-bed, 

 and when the plants are of sufficient size plant them into 

 separate pots, and then place them in the stove, where they will 

 flower and seed ; and some may be planted out in the. open 

 ground. Not worth cultivating except in botanic gardens. 



XXI. HOMALOCA'RPUS (from o/^aXoc, homalos, equal, 

 and Kapirof, karpos, a fruit). Hook, and Arn. in hot. misc. 3. 

 p. 348. 



LIN. SYST. Pentandria, Digynia. Margin of calyx 5-toothed : 

 teeth subulate, minute, hardly permanent. Petals ovate, con- 

 cave, entire. Styles 2, divaricate, short. Fruit roundish-ovate ; 

 mericarps compressed on the back, flat, wingless, constituting 

 2 parallel disks ; commissure very narrow ; ribs 5, filiform, 

 very slender, hidden in the substance of the pericarp, one 

 dorsal, 2 lateral ones near the raphe, 2 middle ones forming the 

 angles, without any vittae ; carpophore entire. Seed less than 

 the cavity of the fruit. Herb annual, erectish, hoary from stel- 

 late hairs, dichotomously branched. Root slender, simple. 

 Leaves petiolate, reniform-roundish, somewhat 5-lobed ; lobes 

 equal, ovate, obtuse, quite entire or deeply lobed ; lower leaves 

 alternate: superior ones opposite. Peduncles axillary and ter- 

 minal, about equal in length to the petioles. Umbels simple, 

 3-6-flowered. Teeth of calyx pilose, almost emulating a fascicle 

 of hairs. Fruit nearly twice the length of their pedicels, which 

 are a line long. This genus comes near to Spandnthe. 



1 H. BOWLESIOIDES (Hook, et Arn. 1. c.) Q. H. Native of 

 the Cordillera of Chili. The ridges or ribs of the fruit are only 

 to be seen on a transverse section of the fruit, because they are 

 sunk in a thin substance of the pericarp. The middle ridges 

 do not expand into wings as in Mulinum, and some other allied 

 genera.
