LX. UMBELLIFER/E.

14. DAUCUS, Linn. 
(From the Greek.) 
Calyx-teeth prominent. Petals with inflexed points, the margins not recurved, 
slightly imbricate in the bud. Disk small, confluent with the conical base of the 
styles. Fruit ovoid or oblong, scarcely compressed, bristly ; carpels dorsally 
compressed, the primary ribs inconspicuous or not prominent, the 4 secondary 
ribs very prominent, expanded into rows of glochidiate bristles, with 1 vitta under 
each secondary rib and 2 at the broad commissure. Carpophore simple or 
bipartite. — Annuals or biennials, usually hirsute. Leaves decompound, with 
narrow segments. Umbels compound, the bracts of the general involucre 
usually dissected. 
Besides the Australian species,, which extends over New Zealand and Western America, the 
genus includes the Carrot and a few other species natives of the northern hemisphere. — Benth. 
1. D. brachiatus (branches at right angles to each other), Sieli. in DC. 
Crod. iv. 214 ; Benth. FI. Austr. iii. 876. An erect or decumbent annual, some- 
times small and slender, sometimes stout and attaining 1 to 2ft., more or less 
sprinkled or hirsute with short stiff hairs. Leaves on slender petioles, twice 
pinnate, with short narrow incised or pinnate segments, usually minutely 
mucronulate. Umbels of about 8 to 5 very unequal rays, with 2 or 8 floral leaves 
or involucral bracts divided into 2 or 8 linear-subulate segments ; one of the rays 
sometimes growing out into a continuation of the stem and bearing another 
compound umbel. Fruit ovoid, varying very much in size, usually scarcely 
2 lines long, with short bristles, sometimes above 3 lines long, the bristles long 
and very fine, or stout and dilated at the base. — Bunge in PI. Preiss. i. 295 ; 
Hook. f. FI. Tasm. i. 161, with the synonyms adduced (except P. pitsilhts, Mich.); 
Seandi.r f/lochidiata, Labill. PI. Nov. Holl. i. 75 t. 102. 
Hab.: A very common South Queensland weed. 
J. D. Hooker includes among the synonyms of this species the Davcus pinnllttg, Mich., of the 
United States of N. America, and on that authority F. v. Mueller takes Michaux’s name as the 
oldest for the species. I). pusilhix appears, however, always to have the umbel, although small, 
regular with numerous rays, and more dissected involucral bracts, as in D. Ca rota, and must 
probably be retained as a distinct species connecting in some measure I), brachiatus with l). 
Carota. — Benth . 
Order LXI. ARALIACEjE. 
Calyx-tube adnate to the ovary ; limb forming a slightly raised line or short 
cup round the summit, truncate or toothed, or quite inconspicuous. Petals 5 or 
more, or rarely 4, usually valvate and shortly inflected at the tip, and often 
cohering, rarely with a long inflected point, or (in a few species not Australian) 
obtuse and imbricate, inserted round an epigynous entire disk. Stamens as many 
as petals or sometimes (in genera not Australian) more, inserted with them round 
the epigynous disk ; anthers versatile, with parallel cells opening longitudinally. 
Ovary inferior, 2 or more celled, or very rarely 1-celled by abortion, with 1 
anatropous ovule in each cell, pendulous from the summit. Styles as many as 
cells, either distinct erect and afterwards recurved with small terminal stigmas, 
or united in a cone, or reduced to a slight protuberance with as many stigmas as 
cells radiating on the summit and often scarcely conspicuous. Fruit more or 
less drupaceous and indehiscent, the epicarp succulent, rarely nearly dry and thin, 
always distinct from the endocarp, which is hardened into as many 1 -seeded 
pyrenes as cells of the ovary, usually laterally compressed. Seed pendulous, 
testa very thin, albumen the shape of the pyrene, with an even surface, or rarely 
ruminate. Embryo minute, near the apex of the seed, the radical superior. — 
Trees, shrubs, or woody climbers, very rarely (in a few specimens not Australian) 
herbs. Leaves simple, digitate or pinnately compound, sometimes very large,
