Ruellia lanceolata, Morong, n. sp. 



This species has a terete, white pubescent stem 3-5 dm. high. Leaves 

 opposite, hirsute on both sides, the hairs often stellate, the veins prominent 

 and white, lanceolate, acute at the apex and sloping at base into a petiole 

 |-2 cm. long, the blade 4-8 cm. long and 1^-3 cm. broad. Flowers in sessile, 

 axillary verticils, 1-3 on a peduncle, many bracted, the bracts and calyx lobes 

 similar, strongly nerved, linear-acuminate. Calyx very deeply 5-parted, ^ as 

 long as the corolla tube, with the bracts hoary hirsute. Corolla purple, 4 cm. 

 long, the tube puberulent outside and very hairy within, longer than the 

 lobes ; lobes 4, subequal or slightly 2-lipped, the upper lip entire, the lower 

 8-lobed, middle lobe longest. Stamens 4, didynamous, 2 perfect ; anther 

 2-celled, one of the cells abortive ; filaments long, decurrent on the corolla 

 tube below their insertion. Capsule flattish, 4-sided, 1^ cm. long, glabrous, 

 olive-colored, 3 or 4 seeded by abortion. 



A somewhat erratic member of the genus. Lobes of the corolla 

 certainly 4. The abortive anther cell looks as if it were a spur at 

 the base of the other. 



In thickets between Pirayu and Jaguaron (66T). April. 



Ruellia ccerulea, Morong, n. sp. 



Suffruticose, 3-4 dm. high, glabrous. Stem square, striate, somewhat 

 swollen at the nodes, with opposite branches. Leaves thick, opposite, ovate 

 or lance-oblong, simple, entire, obtuse at the apex, sloping or abruptly 

 rounded into a short petiole, 3-8 cm. long and 1-2 cm. broad. Flowers in 

 small terminal panicles, one or two on a pedicel ; a pair of linear, acute, 

 keeled bracts at the base of each branch of the panicle, 4-5 mm. long. Calyx 

 persistent, 6-7 mm. long, with 5 rigid subulate lobes longer than the tube. 

 Corolla infundibuliform, with 5 large, spreading, equal lobes, minutely 

 puberulent, 2^ cm. high, of a beautiful blue color, striped inside with deeper 

 blue lines. Stamens on the corolla tube, didynamous, included; filaments 

 short. Style as long as the stamens ; stigma 2-lobed, one lobe flat and much 

 larger than the other. Capsule 2-celled, many-seeded, slightly 4 sided, 

 pointed and somewhat dilated towards the apex, turning brown when mature, 

 2 cm. long. 



Common on the campo at the Falls of the Pilcomayo (1013).

 appressed hairs, about 5 dm. high. Leaves few, opposite, entire, lanceolate- 

 acuminate, under the flowers lance-linear, cuneate at base, hairy like the 

 stem or glabrate, 5-10 cm. long and ^-3 cm. broad. Flowers sessile, or 2 or 3
