Hiraea puldierrima, Morong, n. sp. 



A liana, often climlnng on trees for 10 or 15 m. Stem terete, glabrous or 

 minutely appressed pubescent, especially on the young shoots and among the 

 inflorescence. Leaves deep green, opposite, entire, ovate, rounded at base, 

 acuminate at the apex, shining on the upper surface, pubescent when young, 

 5-10 cm. long, 3-6 cm. broad, usually biglandular at the base of the blade. 

 Petioles 8-12 mm. long. Stipules minute, ovate, at the base of the petioles. 

 Flowers in terminal panicles, often over 30 cm. long. Branches of the panicle 

 opposite, spreading divaricately, 3-10 cm. long, the flowers disposed race- 

 mosely or umbellately. Pedicels purplish, filiform, with minute bracts at the 

 base, sometimes bibracteolate and jointed a little above the base, 8-15 mm. 

 long. Sepals oblong, obtuse, hairy. Petals larger, purple, unguilicate. 

 Ovary hairy. Samara 1, broadly 3-winged, clothed with long, appressed 

 white hairs, crested on the back, becoming more or less glabrate ; wings 

 semiorbicular, separate or partly confluent at the base, striate, a shining 

 purplish-brown when mature, the whole in dried specimens appearing orbicu- 

 lar and about 15 mm. in diameter. Seeds solitary in the centre of the axis of 

 the wings. This liana is a great ornament to the woods when in flower, and 

 its curious fruit are no less attractive. 



Asuncion (626). March. == Balansa 2405. 

 Hiraea Salzmanniana^ Juss., Monog., 312. 



Chaco (431). March. = Balansa 24104. 



In Bull. Soc. Bot. Suisse, i, 34, Prof. Chodat describes a var. 

 glandulifei^a based on this number of Balansa, with the character 

 that the leaves are biglandular at the base, with which our speci- 

 mens agree, but Grisebach in Mart. Flor. Bras., xii, pt. 1, 99, pre- 

 viously described a different variety under the same name, the 

 character being that the calyx is glandular. 



A liana with small panicles or corymbs of yellow flow^ers ; petals 

 6 or Y mm. long, fringed, at the rounded apex. Sepals each bi- 

 glandular and white tomentose. Leaves glabrous or pubescent 

 when young, lanceolate or obovate, acute or apiculate, 10-20 cm. 

 long, and 3-7 cm. broad. Petioles w^hite tomentose, stipuliferous 

 And biglandular at the apex. Wings of the samara separate, cre- 

 nate or undulate on the border, golden-brown at maturity. 



Hiraea macrocarpa, Chodat, Bull. Soc. Bot. Suisse, i, 35. 



Asuncion (226) ; between the Kecolleta and Luque (721). Decem- 

 ber-May. = Balansa 2408. 



This species has round-oval, apiculate or abruptly acute leaves,
