foliorum parvorum bracteati; stamina isomorpha; antherae lineares; connectivum 

 basi in calcar retrorsum breve productum. 



Widely branched half-shrub up to 3 dm. tall, the spreading branches very 

 numerous; internodes 4-7 mm. long, glabrous, with 2 shallow lateral furrows. 

 Leaves isomorphic, linear-elliptic to linear-oblanceolate, up to 18 mm. long and 

 3 mm. wide, acute, tapering to a sessile petiole-like base, entire below, irreg- 

 ularly dentate in the distal half or two-thirds with a few small incurved teeth, 

 glabrous, 1-nerved or with very faint indication of a pair of lateral nerves; 

 secondaries obsolete. Flowers 5-merous, solitary at the end of short (3 mm.) 

 minutely scabrellate peduncles; each peduncle solitary and terminal but appar- 

 ently axillary, subtended at its very base by a pair of reduced leaves, the 

 stem proliferating from the axil of one of the adjacent foliage-leaves. Kypan- 

 thium cup-shaped, thin-walled, about 2.5 mm. long, rather obviously 10-nerved, 

 scabrellate opposite the torus. Calyx-tube prolonged OA mm.; sepals 4.8 mm. 

 long from the torus, from a triangular base, soon narrowed to a subulate tip. 

 Petals "white to pink," ovate, about 6.5 mm. long. Stamens isomorphic but 

 slightly unequal; filaments flat, glabrous; anthers linear, about 3 mm. long, 

 prolonged at base into a terete connective 0.5 mm. long and below the summit 

 of the filament into a straight, retrorse, subulate, dorsal spur 0.5 or 1 mm. 

 long. Ovary superior, subglobose, tipped with 5 erect fleshy lobes; style slender; 

 stigma punctiform. 



TYPE: on wet rocks along Savanna Creek, summit of Cerro Sipapo, Bassett 

 Maguire & Louis Politi 27540; New York Botanical Garden. Paratype: 28223 is 

 identical: it is described as a perennial subshrub 2-4 dm. tall, leaves shining 

 green, flowers pink, stamens pale yellow, along stream, Carlo Profundo, North 

 Branch, summit of Cerro Sipapo. 



Macrocentrum anychioides Gl., sp. nov. 



Planta annua, simplex vel ramosa, caulibus ad nodos setosis; folia isomor- 

 pha, oblongo-elliptica, breviter petiolata, sparse ciliata, glabra; flores 4-meri, 

 breviter pedicellati in axillis foliorum superiorum, basi jugo foliorum reductorum 

 bracteati; stamina isomorpha; antherae lineares; connectivum basi in calcar breve 

 retrorsum productum. 



Annual, according to Maguire, sparsely branched, 1-2 dm. tall; internodes 

 mostly 4-6 mm. long, glabrous; nodes mostly bearing 2 pairs of stipule-like 

 bristles 1-1,5 mm. long. Petioles 2-3 mm. long. Blades isomorphic, oblong- 

 elliptic, up to 1 cm. long and 4 mm. wide, obtuse, acute at base, sparsely 

 ciliate with a few bristles up to 1 mm. long, otherwise glabrous, 1-nerved. Flow- 

 ers 4-merous, solitary and terminal; peduncle 2 mm. long, subtended by two 

 small leaves at base; pedicel about 2 mm. long, merging gradually into the hy- 

 panthiurn. Hypanthium conic, 2.5 mrn. long, narrowly 8-winged, each wing termi- 

 nating in an erect gland-tipped bristle, otherwise glabrous. Calyx-tube about 0.3 

 mm. long; sepals broadly depressed-semicircular, 1.5 mm. long from the torus. 

 Petals purple, oblong, 14 mm. long, Stamens isomorphic; filaments very long and 

 slender; anthers linear-subulate, 3.5 mm. long, including the very short slender 

 retrorse spur. 



TYPE: growing in deep shade on wet rocks along Savanna Creek, summit of 

 Cerro Sipapo, Bassett Maguire & Louis Politi 27539; New York Botanical Garden. 

 Paratype: 28222 is identical, from moist rocky banks, Cano Profundo, north 

 branch, summit of Cerro Sipapo.
