Inflorescence a solitary, androgynous spike, 8–16.5 (18.0) cm × 3.8–7.6 mm, bractless or occasionally the lowermost glume developing into a setaceous bract up to as long as the spike, never surpassing it, long-oblong, cylindrical, densely flowered, with usually more than 60 pistillate flowers, ripe utricles adpressed to ascendant; staminate portion 7.4–21.7 (25.0) mm long. Pistillate glumes from the middle part of the spike 5.2–9.8 × 1.6–2.6 mm, with 2.0– 5.2 mm from base to the widest point, 1.1–1.8 mm wide at half-length from the widest point to the tip, longer than the utricles, elliptic-oblong to fusiform, the apex long-acute, membranaceous, surface glabrous, greenish to straw-colored, occasionally brownish, paler towards the sides and also with the margins narrowly brownish, with the tip narrowly hyaline and the margins sometimes slightly scabrid, 1–2 prominent central veins, greenish, the sides several faintly veined. Utricles 4.3–5.6 × 1.3–1.8 mm, with 2.0– 2.9 mm long from base to its widest point, elliptic, plano-convex, greenish to brownish, pilose with adpressed hairs on the sides more densely arranged towards the tip, the margins with spreading hairs mostly arranged into fascicles, with several conspicuous raised veins adaxially and abaxially, proximally tapered to a substipitate-like base, distally tapered into a conspicuous deltoid beak, distal empty portion of 1.2–1.9 mm long. Achenes 2.1–3.0 × 1.1–1.5 mm, with 1.0– 1.8 mm long from base to the widest point, ovate to obovate, flat to plano-convex, the style sessile. Rachilla smooth, the exserted portion 1.8–3.8 mm long, erect, the hook slightly bend respect to the rachilla axis. Anthers filament linear, flat, as wide as the anthers.</p><p>Distribution.</p><p>Tristan da Cunha archipelago in the S Atlantic Ocean (Fig. 1), in the islands of Tristan da Cunha, Gough, Inaccessible and Nightingale.</p><p>Notes.</p><p>The specimen selected as the lectotype matches the illustration of tab. VI from “ Esquisse Fl. Tristan d’Acugna ”.</p><p>The etymology brevicaulis may seem confusing for a plant up to 61 cm tall. The name was coined by du Petit-Thouars (1808) to refer to short-stemmed plants, as opposed to what he simultaneously called Carex ramosa Thouars, nom. illeg. and Uncinia gracilis Thouars, nom. illeg., also from Tristan da Cunha, a plant with well-developed stems. Later, in the reprint of “ Esquisse de la Flore de Tristan d’Acugna ” (du Petit-Thouars 1811), the name was republished as Carex hamosa . These three names were obliterated from the literature because they are nomenclaturally superfluous with C. uncinata L. f., as this name is cited immediately below as a synonym, despite having priority over them. The plant is represented in tab. V from “ Esquisse de la Flore de Tristan d’Acugna ”, and it matches the specimen P 04023166! [ Uncinia gracilis, Tristan d’Acugna, Herbier du Petit-Thouars], which is an elongated specimen of C. brevicaulis Thouars.</p><p>When coining U. brevicaulis var. gracilior, Hemsley cited in the protologue “ Uncinia gracilis Thouars [...] (excl. synon.). ” Accordingly, he was referring his taxonomic concept of var. gracilior to du Petit-Thouars’s U. gracilis but excluding the type of C. uncinata L. f. This nomenclatural act resulted in a legitimate name.</p></div>	https://treatment.plazi.org/id/427BCE49C95555289F2B453D76857D65	Public Domain	No known copyright restrictions apply.

Mejland 1654 (K 000298924!) .</p><p>Diagnosis.</p><p>Similar to C. austrocompacta K. L. Wilson, from which it can be distinguished by its smaller size of utricles and achenes (see identification key).</p><p>Etymology.</p><p>This species is named after my (P. G. - M.) mother, María Moro Ortega, the kindest person I have ever known, who lovingly cared for me for eighteen beautiful years and who sadly passed away too soon. She lived entirely for her family and friends, caring for everyone around her and always placing others before herself, especially her children. Nearly eleven years later, I am certain that she continues to watch over me from Heaven, and my greatest hope is that she would be proud of the person I have become.</p><p>In addition, by the mention to my mother’s surnames, I also wish to indirectly honour other two people. First my grandmother, Pilar Ortega, who was in many ways a second mother to me, having lived with us throughout those same eighteen years. One of the strongest people I have ever known, she faced the early loss of her husband while raising two daughters on her own, and later endured the loss of one of them, yet never ceased to fight for her family. And second, my aunt María del Pilar Moro Ortega, who, in the absence of my mother and grandmother, was always kind to me and encouraged me in pursuing my goals. She welcomed me into her home and cared for me as her son. She helped me through my most difficult moments and never lost faith in me, even when I had already lost it myself.</p><p>To these three women I owe some of the most important lessons of my life: unconditional love for those we cherish, devotion to family, selfless commitment, and a boundless capacity to give everything for the people we love. As a symbolic reflection of this, the spikes of the newly described C. moro-ortegae are often accompanied by three leaf-like bracts, echoing my mother, my aunt, and my grandmother.</p><p>Description.</p><p>Plants laxly caespitose, with short-elongated rhizomes. Fertile culms 9.5–25 cm long 0.5–1.3 mm wide, erect to slightly curved, longer than leaves, trigonous, smooth. Leaves 6.5–22 cm long, the widest ones 1.5–3 mm wide, the uppermost leaf 1–2.4 mm wide, subcoriaceous to coriaceous, C-shape, sometimes V-shaped, the margins antrorsely scabrid. Inflorescence a solitary, androgynous spike, 1.7–4.8 cm × 2.3–5 mm, the (1) 2–3 (4) proximal-most glumes generally well-developed into setaceous bracts that exceeds the inflorescence length, long-oblong, sometimes narrowly obovate, subclavate to linear, densely flowered, with less than 15–20 pistillate flowers, ripe utricles ascendant; staminate portion 2.8–9 mm long. Pistillate glumes from the middle part of the spike 4–7 × 1.3–2.2 mm, with 0.3–2 (2.5) mm from base to the widest point, 0.5–1.5 mm wide at half-length from the widest point to the tip, longer than the utricles, narrowly deltoid to ovate, the apex acute, herbaceous, glabrous, mostly hyaline, greenish to straw-colored, becoming brownish towards the borders, more rarely entirely pale-brownish, with narrowly hyaline margins, glabrous, 1–3 prominent central slightly-raised veins, paler than the glume, lateral veins faint restricted to the base. Utricles 3.2–4.9 × 0.7–1.4 mm, with 1.5–2.8 mm long from base to its widest point, 0.5–0.9 mm wide at half-length from the widest point to the tip, elliptic, subtrigonous, sometimes plano-convex, greenish to yellowish, sometimes brownish, sometimes whitish, glabrous, two prominent lateral veins, few faintly veined adaxially, sometimes inconspicous, with few slightly-raised veins to sometimes faintly veined abaxially, proximally abruptly attenuated to a stipitate-like base with 0.4–1.1 mm long and 0.2–0.4 mm wide, distally tapered into a conical conspicuous beak, distal empty portion of 0.9–1.6 mm long. Achenes 1.3–2.5 × 0.6–1.2 mm, with 0.5–1.9 mm long from base to the widest point, 0.5–1.1 mm wide at half-length from the widest point to the tip, oblong to elliptic, sometimes obovate, subrounded, the style sessile. Rachilla smooth, the exserted portion 3.1–5.1 mm long, erect, the hook 1.2–1.9 mm long, slightly bend respect to the rachilla axis.

The observed morphological variation could be due to ecological differences, but the fragmentary information provided on the herbarium vouchers prevents the establishment of a relationship between habitat and morphology. Alternatively, it cannot be entirely discarded that these differences were the result of in situ diversification and that more than one taxon might be recognized in Tristan da Cunha. Future studies may help elucidate the situation in this archipelago.</p></div>	https://treatment.plazi.org/id/26B36DC83DC15004A9379C61679379D5	Public Domain	No known copyright restrictions apply.
