"Meehania cordata, " which is one of seven species of the genus " Meehania " and named by the English botanist Thomas Nuttall, are low, with slender runners, hairy; leaves broadly heart-shaped, crenate, petioled, the floral shorter than the calyx; whorls few-flowered, at the summit of short ascending stems; corolla hairy inside, 2-3.5 cm . long; stamens shorter than the upper lip ..

"' Acanthocytosis "'can refer generally to the presence of this type of crenated red blood cell, such as may be found in severe cirrhosis or pancreatitis, This particular cause of acanthocytosis ( also known as abetalipoproteinemia, apolipoprotein B deficiency, and Bassen-Kornzweig syndrome ) is a rare, genetically inherited, autosomal recessive condition due to the inability to fully digest dietary fats in the intestines as a result of various mutations of the microsomal triglyceride transfer protein ( MTTP ) gene.

The pinnae are opposite to subopposite, ( 11 ) 13 20 on a side, spreading, ovate-oblong to linear-oblong, apex acuminate, lowermost pinnae the largest, 20 33 ?11 19 cm, with 11 16 pairs of pinnules, slightly inequilateral, basiscopic basal pinnules 7 10.5 cm long, acroscopic basal pinnules shorter, 4 8.5 cm long, lowermost pinnules usually the largest, distal pinnae stalked 3 6 mm becoming sessile, apices pinnatifid; largest ultimate pinnules 12 19 ?4 8 mm, spaced 5 10 mm distant, obtuse to truncate at apices, margins crenate or cut ca . 1 / 4 2 / 3 toward costule, adaxially glabrous, abaxially glabrous except for scattered small, spreading, brown linear scales on rachises; veins forking 1 2 times, scarcely visible to visible on both surfaces, depressed adaxially and prominulous abaxially; each fertile pinnule usually with 1 4 pairs of inframedial sori.

Trophophore is sessile or nearly so; stalk 0 10 mm, 0-0.4 in, a tenth to a half the length of trophophore rachis; blade is dull, strongly glaucous, whitish green, deltate ( triangular ), thickly leathery, twice pinnate, with apex bent down in vernation, 2 4 cm, 1-1?in, long and 1?4 cm, ?1?in, broad; ternate, the middle division the largest, broadly oblong to rounded-deltoid, the lateral ones similar or rhombic-oblong, all pinnately parted; pinnae closely imbricate ( overlapping ), up to 6 pairs, strongly ascending, sublunate to flabelliform, broadly crenate to incised, or the larger ones radially cleft into cuneiform lobes; distance between 1st and 2nd pinnae not or slightly more than between the 2nd and 3rd pairs, asymmetrically cuneate; basal pinna pair often divided into 2 unequal parts, lobed to tip, margins entire, sinuate to shallowly crenate, apex rounded to truncate, venation pinnate.
