Conservation
CR using the criteria set out by IUCN (2001): B2b (i,ii,iii,iv). The risk of extinction is due mainly to the increasing loss or alteration of habitat and collection of plants for cultivation in tropical gardens.
Distribution
Known only from two localities, c. 30 km apart. In Rio de Janeiro State, this species was initially thought to be restricted to Mundo Novo Hill, a small stretch of Atlantic Forest surrounded by densely urbanised areas. In 1993, various individuals were removed from their habitat to compose the gardens of the Santa Úrsula University, which encircles the type locality. Recently, another population was found at the Serra da Tiririca State Park, located at the neighbouring city of Niterói, although the scattered individuals observed are a few metres from the homes that surround this conservation unit.

Note
The specific epithet reginae was chosen to honour Dra Regina Helena Potsh Andreata in acknowledgment of her numerous contributions to the study of Brazilian Smilacaceae and for the many discussions about them over the years. Calathea fatimae differs from the new species from by the bracts brownish or brownish-green with margin erect, prophyll and interphyll tomentose and sepals 9 – 11 × 3 – 4 mm, tomentose. According to Kennedy & Braga (1997) C. fatimae is characterised by the velvety sheen of the leaves and very striking foliage because of the contrast of the pale yellow to whitish-green midrib region with the dark green above and the purple underside of the leaf. These characteristics are not found in C. reginae, which has entirely green leaves, without markings and sparsely pilose or glabrous (Table 2). Calathea reginae sensu Schumann (1902) belongs to Calathea subgen. Pseudophrynium Körn. series Nudiscapae (Petersen) K. Schum. and is closely related to C. monophylla (Vell.) Körn. and C. fatimae H. Kenn. & J. M. A. Braga. C. monophylla can be distinguished from C. reginae by the bracts brownish or brownish-green, margin erect, coriaceous and lacerate with age, prophyll and interphyll puberulous, sepals 15 – 20 × 3 – 4 mm, puberulous.
