DFC7F9267B585CB1992387FBF2473A93.taxon	diagnosis	Diagnosis Struthanthus longipetiolatus is similar to S. ibe-dzi, S. racemosus, and S. ramiro-cruzii. Plants scandent and pendant with inflorescences in racemes and triads peduncled, the central flower sessile, and the lateral ones pedicellate as in S. ibe-dzi and S. ramiro-cruzii. However, the new taxon is distinguished by its olive green yellowish to pink-reddish stems, petioles, leaves, inflorescence, petals, and style of the pistillate flower and by the long petioles reaching up to 3.2 cm.	en	Maldonado-Borja, María Guadalupe, Cerros-Tlatilpa, Rosa (2025): A new and endemic species of Struthanthus (Loranthaceae) from Guerrero, Mexico.

Haustorium terete, with several epicortical roots at the base of the plant; epicortical roots produce secondary haustoria that attach to the host. Stems 1 – 4.5 mm diameter, voluble, terete to subterete, glabrous, olive green to pinkish, and brown greenish when dried, with lenticels when mature; with epicortical roots. Nodes subterete to complanate, bicarinate mainly when young; stem internodes 3.5 – 8.6 (– 10) cm long. Leaves opposite to subopposite; petioles 1.2 – 3.2 cm long, channelled near the leaf blade base, resupinate; blades lanceolate, ovate, or narrowly ovate, 1.2 – 5.0 × 6.5 – 16.5 cm, apex long acuminate to acute mucronate, base attenuate to oblique, olive green to pinkish-reddish, margin entire, repand when mature, hyaline, venation pinnate, glabrous, papyraceous. Inflorescences indeterminate, axillary, 1 per axil, racemes of triads, rarely paniculated; rachis subterete to applanate, nodes plane, triads opposite to subopposite, decussate; central flower from triad sessile, lateral flowers pedicellate 0.22 – 0.65 mm long. Bracts and bracteoles caducous, cupuliform. Pistillate inflorescences 3.5 – 7.6 cm long, peduncles 0.5 – 1.35 cm long, 10 – 14 (– 16) triads, triad peduncle 0.5 – 1.28 mm long. Staminate inflorescences 3.6 – 10.8 (– 12) cm long, peduncle 0.45 – 1.6 (– 2) cm long, 12 – 16 (– 18) trads, triad peduncle 0.6 – 1 mm long. Pistillate flowers hexamerous. Flower buds cylindrical, rounded at the apex; mature flowers 1.25 – 2.2 × 4.7 – 6 mm, calyculus irregular, 0.1 – 0.2 mm, petals linear 0.5 – 0.75 × 2.8 – 3.65 mm, olive green yellowish to pink-reddish, staminodes one series; nectary globose, hexagonal, surrounding the style; ovary inferior 1 – 1.2 × 2 – 2.6 mm, green yellowish; style strongly convolute, 3.2 – 4 mm long, stigma capitate, pink-reddish when ripe. Staminate flowers hexamerous, central flower of triad sessile, pedicels of lateral flowers 1.2 – 2.2 mm long. Flower buds claviform with rounded apex; mature flowers 2.4 – 4.8 × 6.2 – 10.2 mm, petals linear, 0.8 – 1.25 × 5 – 8.5 mm, olive green yellowish to pink-reddish, without trichomes at the insertion of the petal and the filament; anthers basifixed, dimorphic, and elliptical, 0.9 – 1.18 × 2.2 – 3.2 mm, fully attached to petals, asymmetrical theca, apicular connective; calyculus irregular, green yellowish 0.2 – 0.5 mm, vestigial ovary 1.2 – 2.25 × 1 – 2 mm, nectary globose, hexagonal, surrounding the stylodium base; stylodium straight to slightly wavy, 1.4 – 3 mm long, stigma undifferentiated. Fruit a berry, ovoid, green when immature, orange to vermillion when ripe, bluish-black when dry, glaucous, 3.45 – 6.65 × 8.2 – 10 mm. Seed ovoid, 2.2 – 4.8 × 4.2 – 5.2 mm.	en	Maldonado-Borja, María Guadalupe, Cerros-Tlatilpa, Rosa (2025): A new and endemic species of Struthanthus (Loranthaceae) from Guerrero, Mexico.
