Wormmood-leaved Zozimia. FI. July, Aug. 
2 feet. $ 
2 Z. aneTHiroLIa (D. C. prod. 4. p. 196.) stem terete ; 
leaves supra-decompound, glabrous, glaucous; leaflets linear, 
acute. $.H. Native of Persia, between Teheran and Ispa- 
han. Habit of the first species. Involucra small, glabrous.

Cult. The seeds of these plants should be sown in the open 
ground in spring. A light soil suits them best.

Tribe VIII, 
TORDYLI'NEZ (plants agreeing with Tordýlium in im- 
portant characters), or Orthospérme paucijugate annulate, 
Koch, umb. p. 55. D.C. prod. 4. p. 196. Fruit lenticularly 
or flatly compressed from the back, girded by a thick dilated 
thickened knotted or plicate margin. Mericarps with 5 very 
slender or obsolete ribs: lateral ribs contiguous to the dilated 
margin, or forming the same. Seed flat. This tribe differs 
from tribe Peuceddnea, in the margin of the fruit being ribbed 
or plicate, not smooth, and quite entire. 
CXIII. HASSELQUI'STIA (so named by Linnaeus in honour 
of his pupil Fred. Hasselquist, M.D. who travelled in the Holy 
Land, &c. and died at Smyrna in 1752: his travels are pub- 
lished). Lin. gen. 341. Spreng. umb. prod. p. 11. Koch, umb.

193. Lag. am. nat. 2. p. 93. 
Lin. syst. Pentdndria, Digyjnia, Margin of calyx 5-toothed. 
Petals obovate, emarginate, with an inflexed point; outer ones 
radiant, bifid. Fruit round the rays of the umbels flatly com- 
pressed, with a somewhat thickened accessory winged margin, 
which is hardly tubercularly wrinkled ; those of the disk dissi- 
milar, having one of the mericarps contracted into a hemis- 
pherical urceolus around the other, which is abortive. Meri- 
carps with very slender ribs, the 3 dorsal ones at equal distances, 
and the 2 lateral ones contiguous to the thickened margin, or 
covered by it. Vittæ filiform, one in each furrow, and 2 in the 
commissure. Carpophore bipartite. Seed flattened. This 
genus hardly differs from Tordylium unless in the unequal meri- 
carps of the fruit, and in their margins being hardly wrinkled, 
and quite smooth in the disk on both sides, as in Herdcleum. 
1 H. Aeyprr'aca (Lin. amæn. 4. p. 270. exclusive of the 
synonymes,) stem hispid; leaves scabrous, pinnate; leaflets pin- 
natifid ; segments bluntly lobed ; involucra and involucels small, 
setaceous. ©. Native of Egypt and of Syria, on the 
sea shore. Jacq. hort. vind. t. 87. Tordylium Aigyptiacum, 
Lam, ill. t. 193. f. 2. Poir. dict. 7. p. 711. Flowers white.

phore green. Styles white, erect.

2 H. corpa`ra (Lin. fil. suppl. p. 179.) plant pubescent;

leaves simple, cordate, toothed ; leaves of involucra and invo- 
lucels numerous, setaceous, reflexed. ©. H. Native of the 
Levant. Jacq. hort. vind. 2. t. 193. Tordylium cordàtum, 
Poir. dict. 7. p. 712. Rays of umbels hispid. Leaves of invo- 
lucels subulate, longer than the umbellules. Flowers white. 
Fruit as in most of the species of Tordýlium few, but unequal, 
as in Hasselquistia. 
Cordate-leaved Hasselquistia. Fl. July. Clt. 1787. Pl. 2ft. 
Cult. The species being natives of warm climates, the plants 
are difficult to preserve through the winter. The surest way to 
procure good seed is to sow in autumn, and preserve the plants 
in a frame or green-house till spring, when they should be 
planted out in a warm sheltered situation.
