in mud. Leavps erect, 1-2 inches lone, about a line and a half wide at 

 the summit, marked witli 4-G transverse lines. Umbels 8-l'J-tlo\vcred. 

 Involucre 5-G-leaved. Fruit a line in diameter : e<jnmiissurc with a broad 

 while corky marijin. Vitue red, conspicuous. — This genus does not accord 

 with the present tribe except in habit ; yet wc are unwilling to establish 

 a peculiar tribe for its recei)tion.

Calyx-tube compressed, somewhat 4-an2;led ; the limb 5-toothed. Petals 

 elliptical, entire, acute. Styles filiform. Fruit didymous, much contracted 

 at the commissure, turgid, somewhat pyramidal and 4-angle<l. Carpels 

 without vittfE ; the back flattened, with an oval outline : ribs obsolete. Seeds 

 plane internally, slightly convex externally. — Slender herbs (mostly South 

 American), scabrous with a stellate or simple pubescence. Leaves opposite ! 

 simple, lobed or toothed. Stipules lacerate, scarious. Umbels axillary, 

 simi)le, few-flowered : flowers minute. 



1. B. lobata (Ruiz & Pav.) : decumbent, thinly clothed witli fasciculate 

 and stellate hairs ; leaves reniform, 5-7-lobed ; the lobes entire, rather ob- 

 tuse ; umbels with very short pedicels, 1-3-flowered. — Ruiz {)' Pav. Jl.

Dark moist places about streams, California, Douglas ! Nutfall ! April. 

 — (1) Stem 6-15 inches long, nearly simple; the nodes producing short 

 branches. Leaves about three-fourths of an inch in diameter ; the sinuses 

 acute : lower petioles 1-2 inches long. Fruit densely hirsute witli stellate 

 hairs. Carpels rather smaller than a mustard seed, at first inflated, the 

 calyx not adliering at the back, an empty space being left between it and 

 the pericarp; the seed also occupies but a part of the car])el (the inner 

 portion), so that a transverse section exhibits two cells, one formed by the 

 non-adherence of the calyx at the back, the otlier the cavity of the inflated 

 pericarp which is only partially occupied by the seed. At rnaturity the seed 

 fills the cavity of tlie carpel,- and the exterior cavity collapses, but the dorsal 

 part of the calyx never adheres to the fruit. — We strongly suspect tliat B. 

 tenera, Sprtng., to which Hooker & Arnott (in But. misc. 3. p. 346) refer B. 

 geraniifolia, Cham. &f Schkcht. and B. nodiflora, Presl, is not distinct from 

 this plant. 



Tribe IL SANICULE^. Koch ; DC. 



Transverse section of the fruit somewhat orbicular. Carpels 

 with 5 equal primary and no secondary ribs, or covered with scales 

 or prickles, when the ribs are obliterated. Vittse none, or numerous 

 when the fruit is prickly. Seed flatfish on the face.— Umbels 

 fascicled or capitate, simple, or somewhat irregularly compound.

Calyx-tube echinate ; the teeth somewhat foliaceous and persistent* 

 Petals obovate, erect, connivent, with a long inflexed point. Fruit subglo''
