Leaves: Basal rosette and alternate cauline leaves; lower cauline leaves pinnatifid to bipinnatisect; basal leaves pinnatisect to spinose-serrate. Flowers: Small, whitish, clustered in dense bracteate heads which are in turn arranged in open, long-peduncled panicles. Bracts subtending the heads are yellowish above, lanceolate to linear-lanceolate, mm long, entire or with pairs of lateral spines near the middle; floral bractlets subtending each small flower are usually entire; calyx lobes lanceolate to ovate, obtuse or acute; corollas white or bluish white.

Fruits: Capsule splitting into 2 single seeded mericarps, ovoid, flattened laterally, covered with hyaline scales or tubercules, the ribs obsolete, with several inconspicuous oil tubes. Seed faces flat. Ecology: Found on plains and along water courses, from 4,, ft m ; flowering August-October. Notes: The dense ovoid heads of flowers, superficially resembling Ranunculaceae, along with the prominent, spiky-looking, lateral, subtending bracts make this species stand out.

A good indicator for this species are the pinnatifid to bipinnatisect stem leaves that lack spines if stem leaves spinose-serrate, the species is likely E. Ethnobotany: There is no use recorded for this species, but other species in this genus have uses. Etymology: Eryngium is derived from the Greek word erungos for thistle, alluding to the spiny leaves that characterize this genus; heterophyllum means means that the leaves are different on the same plant.

All treatments were administered every day at h for four weeks. Table 1 Experimental groups. The mice had free access to this diet for four weeks. After this period, we found that the mice were already hypercholesterolemic, compared with healthy mice. At this point, the different treatments were administered orally, every day at h, for the rest of the four weeks along with the hypercholesterolemic diet. The blood samples were drawn from the retroorbital vein; then the mice were sacrificed under anesthesia. Serum was obtained from blood samples by centrifugation, and the different biochemical parameters were measured.
