Old branches cylindrical, grey, finely striate, sometimes peeling in thin, long fibers; young branches strongly flattened at nodes. Leaves short-petiolate to subsessile; petioles 1 – 2 mm long; blades ovate or elliptic-oblong, 1.5 – 2.5 × 0.7 – 1.5 cm, apex rounded or acute, base rounded or obtuse, chartaceous; margins revolute, sometimes folded longitudinally in pressed material and hiding the abaxial surface; adaxial surface glabrous to sparsely pubescent, venation brochidodromous, lateral veins (2 –) 4 – 6 pairs, barely perceptible in older leaves, ascending at 50 ° – 60 ° and fading out, old leaves essentially avenious except for the midvein; abaxial surfaces sparsely pubescent, more densely so along midvein and leaf margin, becoming glabrous with age; midvein slightly sulcate or plane above and prominent below. Flowers solitary, pedicels 8 – 17 mm long; bracts deltoid or linear, c. 2 × 2 mm long; bracteoles linear, c. 3 mm long; floral buds widely pyriform, 3 – 6 mm long, calyx open, 5 - merous, sepals with buttressshaped appendices caused by the coalescence of the tips, internally sericeous; petals 5, sometimes pink in bud, white in the open flower, obovate, 3 – 4 mm long, externally sericeous, ciliate; staminal disk flat, pentagonal, thin, not tearing at anthesis; stamens 160 – 203 (fide Stadnik et al. 2018); ovary 3 – locular, ovules uniseriate on the placenta, 5 – 10 ovules per locule; style c. 4 mm, stigma punctiform. Fruit yellowish and rounded when mature, 5 – 7 × 6 – 6.5 mm, glabrous, crowned by the torn, explanate or somewhat revolute calyx remnants, the pulp scarce; seeds 3 to 7, tightly clustered into a ball, tan, angulatelenticular, 3 – 4.5 × c. 4 mm, the opercular plug columellar, pulpy.	en	Tuler, Amélia Carlos, Conceição, Lázaro Henrique Soares De Moraes, Costa, Grênivel Mota Da, Proença, Carolyn Elinore Barnes (2023): Psidium schenckianum (Myrtaceae): lectotypification, a new synonym and notes on a typical Caatinga species.

03FD6813FF9C8372FF19FF0B31848D9E.taxon	distribution	Geographic distribution: — Psidium schenckianum Kiaerskou is endemic to Brazil. It occurs in Alagoas, Bahia, Pernambuco, Sergipe and northern Minas Gerais (Fig. 2).	en	Tuler, Amélia Carlos, Conceição, Lázaro Henrique Soares De Moraes, Costa, Grênivel Mota Da, Proença, Carolyn Elinore Barnes (2023): Psidium schenckianum (Myrtaceae): lectotypification, a new synonym and notes on a typical Caatinga species.

03FD6813FF9C8372FF19FF0B31848D9E.taxon	biology_ecology	Ecological notes: — Psidium schenckianum occurs mainly in the Caatinga and its interfaces with Cerrado and other neighbouring phytogeographic provinces. The cited habitats are: Atlantic rainforest, campos rupestres, capão, carrasco, dense ombrophilous forest, seasonal deciduous forest and riparian forest. It occurs between c. 120 – 1110 m alt., and collectors frequently cite sandy soil with rocks or boulders. Floral buds were recorded in all months of the year except June and July, with December as the month of highest probability. Flowers were found in all months of the year except June and August, with the month with the highest probability being January. Fruits (at any stage of maturity, from very young to mature) were recorded in all months of the year, with highest probability in March. Mature fruits were recorded between January and May, with the highest probability of occurrence in April. Ethnobotanical notes: — Psidium schenckianum has been used for centuries in the region of the Caatinga, its edible fruits consumed in natura or made into a liqueur or used medicinally for throat infections (Bezerra et al. 2022, Nascimento et al. 2011, Cruz et al. 2013; Nascimento et al. 2013, Cruz et al. 2014). The liqueur is made by infusing the mature fruits for several months in bottles with handmade or industrial sugar cane rum (cachaça) to develop the flavor (Fig. 1 e). However, the use of this fruit has become increasingly restricted to traditional populations, and a reduction in the size of the P. schenckianum populations is probably in motion due to the fragmentation of the Caatinga (Jacob et al. 2020; Liporacci et al. 2017).	en	Tuler, Amélia Carlos, Conceição, Lázaro Henrique Soares De Moraes, Costa, Grênivel Mota Da, Proença, Carolyn Elinore Barnes (2023): Psidium schenckianum (Myrtaceae): lectotypification, a new synonym and notes on a typical Caatinga species.
