1924] Brandegee: PJantae Mexicanae Purpusiarme, XII 405 



ad basim angustatis, apice acutis vel obtusis, 3-5 cm. longis, 1.5- 

 2.5 cm. latis; petiolis usque ad 1.8 cm. longis, supra canaliculatis : 

 inflorescentia dioica axillari ; mascula pedunculis brunneo-pubes- 

 centibus, ca. 2 cm. longis, ca. 30-floris ; periantliiis campanulatis, 

 brunneo-puberulis, lobis triangularibus ; antheris exsertis ; acanthio- 

 carpiis ca. 1 cm. longis, glandulis stipitatis in seriebus duabus ad 

 angulos singulos obsitis. Flores feminei desunt. 



The position of the glands of the acanthocarpium in a double row 

 at each angle is an important character separating the species from 

 P. capitata, which it much resembles. The staminate plant was col- 

 lected at Cameron, Vera Cruz, in 1923. No. 8869. The fruiting plant 

 at the same locality without leaves was collected in 1922. No. 8739. 

 Type, Herb. Univ. Calif. No. 218880. 



Lonchocarpus fuscopurpureus sp. nov. 



Frutex : ramis cinereis : f oliis ca. 7 cm. longis, rhachibus paulo 

 puberulis; foliolis 7-11, obovatis vel ellipticis, coriaceis, ca. 2.5 cm. 

 longis, 1.5 cm. latis, inferioribus minoribus, apice plerumque emargin- 

 atis, supra glabris, subtus sub lente pubescentibus, pellucido-punctatis : 

 racemis usque ad 5 cm. longis interdum 2-3-fasciculatis; pedunculis 

 pubescentibus 1-2-floris; pedicellis brunneo-pubescentibus : floribus 

 ca. 1cm. longis; calyce cyathiformi, brunneo-pubescenti, breviter 

 dentato ; corolla atro-purpurea, vexillo emarginato, extus paululum 

 pubescenti ; stamine vexillari ima basi libero ; ovario pubescenti, ca. 

 6-spermo. Fructus deest. 



The leaflets vary in size and shape. "When very young they are 

 densely appressed hirsute, but in age they become apparently glabrous. 

 The flowers, like those of L. Purpusii, are dark purple. Collected in 

 a barranca near Remudadero, Vera Cruz. No. 8984. Type, Herb. 

 Univ. Calif. No. 220292. 



Machaerium chiapense sp. nov. 



Undique glabrum, ramosum, foliosum : ramis verrucosis : foliorum 

 rhachi 3 cm. longa; petiolo 2-2.5 cm. longo; foliolis 5-7, alternis, 

 ovato-acuminatis, 2.8-3.8 cm. longis, 1.2-2.2 cm. latis ; petiolulis 3 mm.- 

 1 cm. longis: legumine axillari, recto, alam includenti 5-8 cm. longo ; 

 stipite ca. 8 mm. longo. Flores, bracteae, stipulae desunt. 



The specimens are branches bearing only leaves and mature fruit. 

 The leaves in drying have become dark colored. Collected along the 

 road between Tuxtla Gutierrez and Jalisco, Chiapas. No. 9137. Tj'pe,
