The Manuleae, a tribe of Scrophulariaceae) SUTERA asbestina Hiern: An undershrub, woody and intricately branched below, subherbaceous and divaricately branched near the top, nearly glabrous, minutely glandular-papillose above, somewhat viscid and shining, apparently perennial, spreading or suberect, 0.5–1 ft. high; branches opposite or alternate, rather slender, wiry, rigid, divaricate, procumbent or ascending, older ones pallid; branchlets green, leafy; leaves obovate or oblanceolate, rounded or apiculate, wedge-shaped at the shortly petiolate base, opposite or the upper alternate, occasionally quasi-fasciculate, firm, glistening with small sessile glands, entire or sparingly toothed, 0.2– 0.4 in. long, 0.1– 0.1875 in. broad; petioles up to about 0.125 in. long; flowers axillary and racemose, rather few, about 0.6 in. long when expanded, white; racemes lax, terminal, at first corymbose, afterwards elongated and oblong, corymbosely arranged; pedicels 0.25– 0.5 in. long, rigid, 1-flowered; bracts spathulate or sublinear, smaller than the leaves; calyx 0.1 in. long in flower, about 0.125 in. long in fruit, glandular, deeply 5-lobed; segments linear, obtuse; corolla-tube subcylindrical, slender, dilated, and curved near the top, minutely glandular-papillose outside; limb spreading, about 0.5 in. in diam.; lobes broadly ovate, 0.167– 0.4 in. long; stamens and style included; capsule ovoid-oblong, somewhat glandular scaly, 0.167– 0.25 in. long. (from JSTOR Global Plants website / Flora Capensis) SUTERA batlapina Hiern: An undershrub, woody and intricate below, subherbaceous and divaricately branched above, subglabrous, minutely glandular-pulverulent above, slightly viscid and shining, perennial, much branched, decumbent or ascending, 8–10 in. high or more; branches opposite or alternate, sometimes quasi-fasciculate, rigid, patent or erect-patent, slender, wiry, moderately leafy; leaves opposite or alternate, often quasi-fasciculate, oblanceolate, obtuse, wedge-shaped to the subsessile base, incisely few-toothed or entire, rather thick, glistening with small sessile glands, 0.167– 0.333 in. long, 0.042– 0.083 in. broad; flowers axillary and racemose, blue, about 0.333 in. long, rather numerous, together forming leafy terminal lax oblong racemes; pedicels rather rigid, divaricate, 0.167– 0.333 in. long, glandular-papillose; bracts entire, smaller than the leaves; calyx glandular-pulverulent, deeply 5-lobed, about 0.083 in. long; segments sublinear or oblong, obtuse; corolla-tube cylindrical and straight except the slightly dilated and funnel-shaped subgibbous upper part, nearly 0.333 in. long, viscid and minutely sessile-glandular outside; limb spreading, about 0.4 in. in diam.; lobes obovate-oblong, 0.167– 0.2 in. long, rounded, entire; stamens and style included; capsule ovoid-oblong, shining, sprinkled with small sessile glands, 0.167 in. long. (from JSTOR Global Plants website / Flora Capensis) SUTERA integerrima Hiern: An undershrub, woody below, subherbaceous at the top, nearly glabrous, minutely glandular-puberulous, somewhat viscid and shining, much branched, perennial, 1–1.5 ft. high; branches opposite and decussate or the upper alternate, slender, wiry, rather rigid, subvirgate or flexuous, suberect or ascending; internodes mostly exceeding the leaves; leaves opposite or alternate, sometimes quasi-fasciculate, narrowly oblanceolate or sublinear, obtuse, wedge-shaped at the base, quite entire or occasionally sparingly-toothed, firm, minutely glistening with small sessile or hair-like glands, 0.3– 0.6 in. long, 0.05– 0.167 in. broad; petioles up to about 0.2 in. long; flowers racemose, rather numerous, about 0.5 in. long when expanded, orange-coloured; racemes lax, terminal, somewhat flexuous, oblong, corymbosely arranged; pedicels 1-flowered, rigid, 0.25–1 in. long; bracts solitary, basal, sublinear, smaller than the leaves; calyx 0.167 in. long in flower, 0.167– 0.2 in. long in fruit, glandular-puberulous, deeply 5-lobed; segments linear, obtuse; corolla-tube about 0.417 in. long, glandular-puberulous outside, subcylindrical, rather slender, somewhat dilated curved and ventricose near the top; limb spreading, about 0.333 in. in diameter; lobes oval-rotund, rounded, entire, about 0.125 in. long; stamens and style included; capsule oblong, glandular-squamulose, about 0.1875 in. long. (from JSTOR Global Plants website / Flora Capensis) The leaf blade is narrowly to broadly elliptic, sometimes oblanceolate, and entire to toothed, but it is always pubescent on both surfaces with a mixture of glistening glands and tiny stalked glandular hairs. Another characteristic feature of the species is the dense covering of glistening glands on the capsules (and ovaries); tiny glandular hairs may also be present, but they are dominated by the glistening glands. In Namibia, these glistening glands are smaller than in specimens from the Cape (including the Richtersveld) and very shortly stalked; also the leaves are always toothed. These are perhaps the marks of a distinct race, but scarcely of a distinct species. The overall hairiness of the leaves will at once distinguish J. integerrima from J. albiflora, in which the leaf blade is either glabrous or has a few scattered glistening glands above, thickly clad in glistening glands below with only a few tiny stalked hairs confined to the midrib. Jamesbrittenia integerrima has been confused with J. argentea. Jamesbrittenia integerrima and J. argentea can be distinguished at a glance: the inflorescence mostly bracteate in J. integerrima, decidedly leafy in J. argentea, which is confined to the southern Cape coastal districts.

Dwarf shrublet or perennial herb, stems 100-600 mm long, up to 8-15 mm in diam. at base of plant, erect, ascending or spreading, fastigiate or more laxly branched, glandular-puberulous, hairs up to 0.1-0.2 mm long, sometimes less than 0.1 mm, glistening glands as well, these most conspicuous when hairs less than 0.1 mm, leafy mainly on the lower parts. Leaves opposite becoming alternate upwards, axillary leaf tufts often small or wanting, largest primary leaves 7-25 x 2.5-9 mm, elliptic to oblanceolate, apex obtuse to subacute (the broader the leaf the more obtuse the tip), base tapering to form a petiolar part accounting for up to c. 1/3 total leaf length, margins entire or with up to 4 pairs of small teeth, lowermost pair occasionally reaching c.halfway to midrib, both surfaces glandular-puberulous, hairs up to 0.1-0.2 mm long, sometimes less than 0.1 mm, glistening glands as well. Flowers solitary in the axils of the upper leaves, these rapidly becoming smaller and passing into bracts, forming long racemes or panicles. Pedicels up to 7-26 mm long. Calyx tube 0.2-0.3 mm long, lobes 2.1-5 x 0.5-1 mm, lanceolate-oblong to subspathulate, glandular-puberulous, hairs up to 0.1-0.2 mm long, glistening glands as well. Corolla tube (7-)9.5-12(-17) x 1.8-2.2 mm in throat, cylindric, abruptly expanded near apex, limb oblique, 8-18 mm across lateral lobes, posticous lobes 3.5-8 x 2.7-4.5 mm, anticous lobes.3-8.5 x 2.4-5 mm, all lobes cuneate-oblong, ± truncate to retuse, glandular-puberulous outside, hairs up to 0.15-0.2 mm long, glistening glands as well, transverse band of clavate hairs in throat extending briefly onto lower lip, lobes usually white, very rarely cream or yellow, throat yellow to orange, the colour sometimes radiating onto base of lobes, these sometimes also marked with a light blueish streak. Stamens: posticous filaments c. 1-2 mm long, anthers 0.8-1.3 mm; anticous filaments 0.5-1 mm long, anthers 0.5-0.8 mm, all filaments glandular-puberulous. Stigma 0.2-0.3 mm long. Style (5-)7-10(-14) mm long. Ovary c. 2-3 x 0.8-1.2 mm. Capsules 4-9 x 3-3.4 mm, glistening glands all over, often minute glandular hairs as well. Seeds c. 0.6-0.7 x 0.3-0.5 mm. Flowering has been recorded in all months. (from http://www.worldfloraonline.org/taxon/wfo-0001259650 / Vollesen, KB. 2013. 126. Acanthaceae (Part 1). Fl. Zambes. 8(5): 1 - 184.
