200 Plants Collected in Paraguay. 



lip nearly white, in globular heads, the heads in opposite leaf axils, 

 on short peduncles, bristly with the lanceolate bracts and calyx 

 teeth. Common on the river-side. 



Hyptis cinerea, Morong, n. sp. 



Stem rather slender, tetragonous, deeply grooved in the centre and sulcate 

 on the sides, cinereous-pubescent below and densely and closely hispid above, 

 with many opposite, erect, strict branches, 6-15 dm. high. Leaves narrowly 

 lanceolate, 6-10 cm. long, 5-15 mm. wide, acuminate, unequally and sharply 

 serrate, pellucid-dotted, cinereous pubescent on both sides, sloping into a 

 winged petiole 10-20 cm. long. Jnternodes on the stem 5-15 cm. long. Heads 

 few, solitary, axillary, globular, 8-10 mm. in diameter, on peduncles 10-15 

 mm. long. Bracts equalling the heads or shorter, lanceolate, hispid. Calyx 

 campanulate, 5 mm. long, glabrous between the nerves, ciliate on the margins ; 

 teeth longer than the tube, hispid. Corolla when in flower much exserted 

 beyond the calyx, about 1 cm. long, spotted white and purple. Receptacle 

 villous. 



Approaches H. hrevipes, but the leaves in that are glabrate and 

 black spotted, ovate, the bracts ciliate and broader, the flowers 

 scarcely surpassing the calyx, and the stems not grooved as in this. 



Luque (304); Pilcomayo River (924). November-February. 

 = Balansa 1006 a. 



Hyptis dumetorum^ Morong, n. sp. 



Stems 9-12 dm. high, tetragonous, the angles obtuse, densely white villous, 

 even woolly towards the top, strict, sparsely branching. Heads globose, soli- 

 tary, in opposite leaf axils, the largest 10-14 mm. in diameter ; peduncles 

 pubescent, 8-20 mm. long. Bracts subulate, villous, shorter than the heads. 

 Calyx slightly inflated in the middle, sparingly pubescent, 10-nerved, reticu- 

 late-veiny, elongated and strongly recurved in fruit, naked in the interior, 

 the fruiting 6 or 7 mm. long ; teeth straight, 3 times shorter than the tube, 

 equal, pubescent. Corolla scarcely exceeding the calyx, purplish in tint. 

 Receptacle woolly. Seeds oval. Leaves ovate, rounded or truncate at the 

 base, unequally dentate, densely fuscous-villous, rugose veiny and almost 

 woolly beneath, the lowest on short petioles, the uppermost sessile; blades 

 5-7 cm. long, 3-5 cm. broad at the base, the uppermost becoming sessile bracts 

 1-2 cm. long. 



This species seems to approach B. recurvata, Poit,, but that as 

 described has naked receptacles, leaves always petioled, smaller 

 heads and longer peduncles. 



A conspicuous plant in thickets around Asuncion (633). March- 

 April. = Balansa 1009.
