Guerrero: Mochitlán: Cerro Tepila, 5 km al O de Coaxtlahuacán (♀), 2000 m, 26 July 1982 (fl), A. Núñez 875 (holotype: FCME; isotype: MEXU).</p> <p>Perennial hemiparasitic shrubs, pendulous, with sympodial branching; stems terete, green when young, sulcate, grayishbrown when old, with conspicuous reddish lenticels, glabrous, epicortical roots usually present. Leaves opposite to decussate; petiole 5–10 mm long, canaliculate; blades ovate to lanceolate, 3–5.5 × 2.4–4.7 cm, apex apiculate, sometimes acute, base usually subcordate, sometimes truncate, margins entire to repand, sometimes slightly undulate, venation pinnate, glabrous, coriaceous. Inflorescence a raceme of triads, indeterminate and axillary, usually 1 (2) per axil, 2.5–6.2 (10.5) cm long, glabrous, with 4–10 pairs of triads, opposite to alternate, central flower of the triad sessile; inflorescence peduncle 0.4–1.5 cm; triad peduncle 3–10 mm; pedicels of lateral flowers 2–4 mm; bracts and bracteoles caducous. Pistillate flowers, 3–4 × 1.5–2 mm, actinomorphic, hexamerous. Calyx green, reduced to a calyculus with the margin undulate to irregularly dentate, glabrous. Corolla greenish-yellow, 2.2–3 mm long, petals free, glabrous. Staminodes equal to the number of petals, adnate to the corolla, opposite the petals, conspicuous. Ovary inferior, 1.5–2 × 0.8–1.2 mm, glabrous. Style strongly convoluted, 1.8–2.5 mm long, stigma capitate. Staminate flowers, 5–6 × 3–4 mm, actinomorphic, hexamerous. Calyx green, reduced to a calyculus with the margin undulate to irregularly denticulate, glabrous. Corolla greenish-yellow, 3.7–4.3 mm long, petals free, glabrous. Stamens equal to the number of petals, adnate to the corolla, opposite the petals, inserted at two different heights, three ¾ up the petal and three ½ up, arranged alternately. Anthers versatile, 1.7–2.3 × 0.7–1 mm, with a connectival horn, dehiscence longitudinal. Ovary inferior, 0.8–1 × 0.5–0.8 mm, glabrous. Style slightly curved near the apex, 1–1.2 mm long, stigma undifferentiated. Berry ovoid, 4–6 × 3–4 mm, glabrous.</p> <p>Distribution and Habitat: Struthanthus ramiro-cruzii (Figure 1) is endemic to Guerrero, Mexico, where it is restricted to the physiographic province of the Southern Coastal Range (Cervantes et al. 2008) in the Guerrerense region. It grows in oak and pine-oak forests, at elevations from 1860 to 2410 m. Flowering occurs from May to August, whereas fruiting takes place from September to November. The only known host of S. ramiro-cruzii is the genus Arbutus Linnaeus (1753:395) (Ericaceae).</p> <p>Additional specimens examined: MEXICO: Guerrero.

Trayecto Tlatlauquitepec-Zapotitlán Tablas (♂), 2340 m, 1 July 1989 (fl.), E. Guízar N. 2068 (MEXU).</p> <p>Etymology: The specific epithet honors Ramiro Cruz Durán in recognition of his continuous work on the description and knowledge of the flora of Guerrero, Mexico.</p> <p>Discussion: Struthanthus ramiro-cruzii is similar to S. cansjerifolius (Oliver) Eichler (1868: 87), S. deppeanus and S. quercicola (Schlechtendal &amp; Chamisso) Blume (1830: 1731). These species share similar inflorescence length, pedunculated triads, caducous floral bracts and bracteoles, and corolla color. They are contrasted in Table 1.</p> </div>	https://treatment.plazi.org/id/03EA87FCA475FFA1FF63E224E82684E0	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
