bristly or tiiberculate. Carpel with somewhat proirJnent or obso- 
lete ribs, thickish pericarp, and prominent groups of strengthening 
cells. Stylopodium somewhat prominent. Oil-tnbes 2 on the 
commissural side. 
f)4. Discopleura. Calyx-teeth small or obsolete. Fruit 
ovate, glabrous. Carpel with dorsal and intermediate ribs filiform 
to broad and obtuse; the laterals very thick and corky, closely con- 
tiguous to those of the other carpel, forming a dilated obtuse or 
acute corky band; all sul)tended by strengthening cells. Oil-tubes 
2 on the commissural side. Seed nearly terete (somewhat silicate 
beneath the oil-tubes) or with a flattish face. 
(6). Fruit with plane seed-face, conical stylopodium, and numerous 
oil-tubes. 
55. Berula. Calyx-teeth minute. Fruit nearly round, 
emarginate at base, glabrous. Carpel nearly globose, with very 
slender inconspicuous ribs, thick corky pericarp, and no strengthen- 
ing cells. Oil-tubes numerous and contiguous, closely surround- 
ing the seed cavity. Seed terete. 
56. iEgopodium. Calyx-teeth obsolete. Fruit ovate, gla- 
brous. Carpel with equal filiform ribs (with broad and equal in- 
tervals), each containing strong groups of strengthening cells; peri- 
carp with no oil-tubes, but with a layer of large parenchyma cells 
surrounding th.e seed-cavity (as in Cryptotcenia). Stylopodium 
prominent. Carpel and seed-section nearly round. 
(7). Fruit with plane seed-face, depressed stylopodium, no oil-tubes, 
and continuous band of strengthening cells about the seed-cavity. 
57. Bowlesia. Calyx-teeth rather prominent. Fruit broadly 
ovate, with narrow commissure (carpels appearing nearly dis- 
tinct), and stellate pubescence. Carpel turgid, becoming depressed 
on the back, with neither ribs nor oil-tubes; the whole dorsal 
region inflated, the seed-cavity being on the commissural side of 
the carpel-section. Seed flattened dorsally ; the face and back 
plane or convex. 
t f t Carpels (as well as fruit) strongly flattened laterally: stylopo- 
dium depressed. 
58. Hydrocotyle. Calyx-teeth minute or obsolete. Fruit 
more or less orbicular. Carpel with 5 primary ribs (additional
