CF6387CAFFB3FF8BF539FF67FA64FABD.taxon	distribution	DISTRIBUTION, HABITAT AND ECOLOGY. — Psychotria speciosa occurs as isolated plants in mid-elevation forests at 700 - 1500 m. Its ecology is poorly known, but collectors’ notes indicate it is rare in high valleys along streams associated with species of Cyathea Sm. and Cyrtandra J. R. Forst. & G. Forst.

Infructescence terminal or lateral by displacement. Fruits sessile or scarcely pedicellate, clustered, ellipsoid-ovoid to subglobose, 1.5 - 2.2 cm long, 0.8 - 1.1 cm wide, red at maturity, apex umbonate. Pyrenes ellipsoid, 1.4 - 1.7 cm long, 0.7 - 1.0 cm wide, 0.2 - 0.4 cm thick, ventral surface plane, dorsal surface with two marginal and one central crests; preformed germination slit ventral, extending ¼ - 1 / 3 distance from apex (Fig. 5 B). Endosperm not ruminate, lacking reddish alcohol-soluble pigment. IDENTITY OF PSYCHOTRIA TRICHOCALYX, COMB. NOV. Drake Del Castillo (1886) considered Nadeaud’s “ Var. D cymosa ” of P. speciosa to represent a distinctive species with inflorescences having villous peduncles and calyces and described it as Uragoga trichocalyx Drake, citing two specimens (Lépine 184 and Nadeaud 343). He later (Drake Del Castillo 1892) transferred it to Calycosia A. Gray as Calycosia trichocalyx (Drake) Drake. Calycosia is a genus of six to eight species distributed in Fiji, Samoa, the Solomon Islands, and New Guinea. It is closely related to Psychotria (Smith & Darwin 1988; Andersson 2002) and is distinguished morphologically by the capitular or capitular-cymose inflorescences with conspicuous, often numerous, pale green to white, free or united, involucrate stipule-like deciduous bracts, and flowers with a large, infundibular calyx limb, deciduous in fruit (Smith & Darwin 1988). However, Smith & Darwin (1988) stated these characters are not reliable in separating the genus from all groups of Psychotria. Our observations reveal that young inflorescences of many Pacific Psychotria species are enveloped by stipules or stipule-like bracts. Capitular-cymose inflorescences occur in several Marquesan and Micronesian Psychotria species (Fosberg & Sachet 1991; Lorence & Wagner 2005; Lorence & Wood 2012). Furthermore, calyx limb size and lobing varies considerably between Psychotria species. For these reasons we believe C. trichocalyx is best placed in Psychotria and make the following new combination.	en	Lorence, David H., Florence, Jacques, Meyer, Jean-Yves (2017): Reassessment of the Psychotria speciosa G.

CF6387CAFFB3FF89F75DFA02FA81F83B.taxon	discussion	REMARK Drake Del Castillo (1886) cited two syntype collections, Lépine 184 and Nadeaud 343 (a mixed collection), both at Paris. F. R. Fosberg proposed but never published this combination in his herbarium annotations of the syntypes. We hereby designate Lépine 184 (2 sheets) as lectotype. This species is distinguished from other Tahiti congeners by a shortly pedunculate, 3 - 4 - flowered inflorescence covered by spreading reddish-brown hairs, externally pilose campanulate calyx with short triangular to oblong lobes, pilose hypanthium and fruit, and white corollas with lobes puberulent distally (Fig. 1 B, C).	en	Lorence, David H., Florence, Jacques, Meyer, Jean-Yves (2017): Reassessment of the Psychotria speciosa G.

CF6387CAFFB3FF89F75DFA02FA81F83B.taxon	description	DESCRIPTION OF A NEW SPECIES, PSYCHOTRIA PAULAE J. - Y. MEYER, LORENCE & J. FLORENCE, SP. NOV. Intensive botanical surveys on the island ofTahiti have produced numerous new collections and new locations for Psychotria, including a distinctive new species discovered by J. - Y. Meyer at one locality on the western slopes of Tahiti. This new species does not match any of the recognized Pacific Island taxa but is most similar to P. speciosa. Tahiti currently has nine Psychotria species, including P. trichocalyx, comb. nov., and the new species P. paulae, sp. nov., described below.	en	Lorence, David H., Florence, Jacques, Meyer, Jean-Yves (2017): Reassessment of the Psychotria speciosa G.
