Leaves chartaceous, petioles 2.5–7 mm long, blades (0.8–)1.2–3.4 × (0.3–) 1.6–1.8 cm, ovate, base cuneate, apex acute or attenuate, adaxial surface sparsely pubescent, abaxial surface pubescent, with simple, 4–5-celled non-glandular trichomes, falcate, 0.2–0.3 mm long, absent along the veins, margins slightly sinuous, ciliate. Flowers solitary, terminal, pedicel 1–1.5 cm long, enlarged distally, hirsute, with simple or branched, 5–7-celled non-glandular trichomes, 1–4 mm long, also with few crooked trichomes 0.3–0.5 mm long. Bracts 1–2 mm long, subulate. Calyx green, ovate, regularly deeply 5-lobed, lobes 1.7–2 × 0.7–0.9 cm, apex acute, outer surface pubescent, the trichomes like those on the stems, leaves and pedicels, inner surface glabrous. Corolla with valvate aestivation, campanulate, green, tube 3–5.2 cm long, pubescent on outer and inner surfaces, with simple, crooked, non-glandular, ca. 0.3 mm long, lobes shorter than the tube, ca. 1 cm long, with few crooked and slender trichomes 0.2–0.3 mm long, apex obtuse, revolute at anthesis; stamens exserted ca. 1 cm from the corolla tube, equal length reaching the same level, the filaments adnate ca. 1 mm to the base of the corolla tube, enlarged and glabrous at the base, attenuate at apex, the free part 2.5–4 cm long, anthers basifixed, linear, opening by longitudinal slits, 7–8 × 2 mm, shortly lobed at base (ca. 1 mm long), brown, not connivent, thecae not confluent at the apex; ovary glabrous, conical, 5–6 × 6 mm, with a nectariferous disk around, style 6–8 cm long, filiform, stigma saddle-shaped, placed ca. 1 mm above the anthers. Fruits not seen.</p><p>Distribution and ecology:— Dyssochroma caatingae was collected in a region known as Serra do Periquito in the municipality of Floresta, located in the center of Pernambuco state, within the Caatinga domain, Brazil (Fig. 3). This distribution represents the first recorded occurrence of the genus outside the Atlantic Forest domain (Orejuela et al. 2017; Stehmann &amp; Giacomin 2025). The Serra do Periquito is characterized by different vegetation types, with a predominance of hyper- and hypoxerophilous caatinga on the slopes, and seasonal forest at higher elevations (Araújo Filho et al. 2001). The new species occurs in seasonal forest above 880 m and was collected with flowers in February.</p><p>Preliminary conservation assessment:— Dyssochroma caatingae is only known from the type specimen, collected outside of protected areas, having an AOO of less than 10 km 2. At present, no detailed information is available regarding its population size or the potential threats to its survival. Therefore, it should be classified as (DD) Data Deficient (IUCN 2012, 2024). Future field expeditions in the Serra do Periquito and seasonal forests of the Caatinga domain in Pernambuco state are essential to provide more information about its distribution and ecology.</p><p>Etymology:— The epithet is a reference to the first record of Dyssochroma in the Caatinga domain. Until now, the genus was considered restricted to the Atlantic Forest domain in Brazil.</p><p>Taxonomic notes:— Dyssochroma caatingae can be distinguished from the three previously described Dyssochroma species mainly by its pubescent indumentum. It has a variety of types of non-glandular trichomes covering its vegetative and reproductive organs, which are multicellular, either simple or branched on the pedicels and calyces, whereas D. atlanticum, D. longipes and D. viridiflorum are characterized as glabrous or glabrescent plants, rarely with sparse, minute unicellular simple trichomes (Stehmann &amp; Giacomin 2025). Among these three species, D. caatingae is most similar to D. viridiflorum, both sharing green calyces and corollas. Notably, the type specimens of D. caatingae were previously identified in herbarium collections as D. viridiflorum . However, these species differ in the characteristics detailed in the diagnosis above. Additionally, although both species occur in Pernambuco state, D. caatingae is found in the Caatinga domain, while D. viridiflorum has been recorded in the Atlantic Forest domain and has a wider distribution, also recorded in the states of Bahia, Ceará, Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, and Paraná (Stehmann &amp; Giacomin 2025).</p></div>	https://treatment.plazi.org/id/03C987DAFF983D67FF5565EC86E0FDB4	Public Domain	No known copyright restrictions apply.

Fiaschi 1722 (CEPEC) .</p><p>Distribution and ecology:— Dyssochroma jardimii has been recorded in the Atlantic Forest of southern Bahia state (Fig. 3). It occurs in moist forests, locally referred to as matas higrófilas (Mori et al. 1983), at elevations ranging from 450 to 1,000 m. The species was collected with flowers from January to August, and with fruits from May to July, and in October.</p><p>Preliminary conservation assessment:— Dyssochroma jardimii was found in a region of the Atlantic Forest still considered a biodiversity knowledge gap (Ostroski et al. 2020, Gaem et al. 2024). Based on available collections, its estimated EOO and AOO are 8,518.170 km ² and 32 km ², respectively, with several specimens collected within protected areas, such as Parque Estadual Serra do Conduru, Parque Nacional de Boa Nova, and Reserva Biológica de Una. The species meets Criterion B2, with an AOO of less than 500 km ². However, due to the lack of data on habitat decline and subpopulation size, we are unable to assign it to a threat category, as at least two of the three conditions under Criterion B must be met to justify such a classification. Therefore, we suggest that D. jardimii should be considered Data Deficient (DD).</p><p>Etymology:— The specific epithet is dedicated to Dr. Jomar Jardim, the current curator of the CEPEC herbarium, who has devoted his life to both fieldwork as a skilled woodsman (mateiro) and as a professor of Botany. He is one of the most prolific collectors in the Atlantic Forest of southern Bahia, with extensive knowledge of the state’s flora. Furthermore, he contributed by collecting some specimens of this new species.</p><p>Taxonomic notes:— Several specimens of Dyssochroma jardimii were previously identified as “ Dyssochroma sp. nov. ” or “ Dyssochroma aff. viridiflorum ” in the analyzed herbarium collections. Stehmann &amp; Giacomin (2025) noted that specimens of D. viridiflorum collected in southeastern region of Bahia state are pilose, while specimens from other regions of Brazil are glabrous. However, these pilose specimens from southeastern Bahia with 3–7-celled non-glandular trichomes on young stems, calyces and corolla tubes are here recognized as a distinct species. Dyssochroma jardimii and D. viridiflorum are similar in the size and shape of leaves, calyces and corollas. Nonetheless, they can be distinguished by the characteristics outlined in the diagnosis.</p><p>Orejuela (2021), in his thesis on the evolution of epiphytism in Solanaceae, conducted a molecular analysis based on plastid DNA from various genera of the tribe Solandreae and reported a presumed new species within Dyssochroma . It was designated as Dyssochroma sp. nov. 1, based on the specimen Amorim 3544, which corresponds to D. jardimii .</p><p>The two new species described in this study share similar pubescent indumentum on young stems, calyces and corollas. However, Dyssochroma jardimii has longer leaves measuring (4–)6.2–9.8(–14.3) cm (vs. leaves (0.8–) 1.2–3.4 cm long), elliptic blades (vs. ovate), glabrescent abaxial surfaces, with trichomes concentrated along the midvein (vs. entirely pubescent), irregularly deeply 5-lobed calyx (vs. regularly 5-lobed), lobes (2.3–) 2.8–3.6 cm long (vs. 1.7–2 cm long), corolla with purplish or brownish stripes (vs. green without stripes), and ovary 3–4 × 3 mm long (vs. 5–6 × 6 mm long in D. caatingae). Additionally, D. jardimii has only straight 3–7-celled non-glandular trichomes (vs. a variety of non-glandular trichomes types in D. caatingae, including simple, 2–3-branched, falcate, crooked, long and slender 4–12-celled). These species also have a distinct distribution, with D. jardimii occurring in the Atlantic Forest domain, specifically in the moist forests from southeastern Bahia state, whereas D. caatingae is found in seasonal forest within the Caatinga domain in Pernambuco state.</p></div>	https://treatment.plazi.org/id/03C987DAFF9C3D65FF5562768635F984	Public Domain	No known copyright restrictions apply.
