lose-hispid, 3-6 dm. high, springing from thick ligneous roots. Leaves oppo- 

 site, ovate or lanceolate-ovate, strongly crenate-serrate, acute or obtuse at the 

 apex, sloping at base into a petiole 5-15 mm. long, densely hispid on both 

 sides, about 7-nerved on each side, scarcely penninerved, the blades 3-7 cm. 

 long, l^-2j cm. wide. Flowers in dense globular or ovate heads, the heads 

 solitary, axillary, on hispid peduncles 3-5 mm. long. Bracts imbricated, 

 cuspidate-acuminate, densely hirsute-ciliate and hispid, 2-3 mm. broad, 

 4 mm. long, nearly hiding the flowers. Calyx membranaceous, compressed, 

 bifid, puberulent, dividing and falling off with the seeds at maturity. Corolla 

 yellow, ampliate, 2-lipped, upper lip entire, lower lip 3-lobed, downy on either 

 side under the lobes, about 3 mm. long, only the lobes showing under the 

 acumen of the bracts. Seeds flattened-globose, 1|- mm. long, pubescent, split- 

 ting at maturity into 2 hemispherical nutlets. 



The plant has a strong mint-like odor, and abounds in the neigh- 

 borhood of the Recolleta, a well-known cemetery about 2 miles from 

 Asuncion (62). October-November. 



Valerianodes Jamaicense (L.), Med. ThiL Bot., i, 177. 



Asuncion (108). November. 



Common in the waste grounds of the city. The numerous long, 

 slender spikes (12-33 cm.) give it a very striking look, although it 

 is such a common weed that everybody at Asuncion wondered to 

 see me gather it. 



Verbena Bonarieiisis, L., Sp. PL, 20. 



Asuncion (173) ; Pilcomayo River (1540). November-April. 



Verlbena Peruviana (L.), Brittou. 



Erinus Peruvianus, L., Sp. PL, 630. 



Verbena chamcedrifolia, .Juss., Ann. Mus., vii, 73. 



Asuncion (51). = Balansa 1024. 



This scarlet-flowered, trailing Vej^bena seems to grow all over 

 Paraguay, and nearly all the year round. I found it not only in 

 copses about Asuncion, but also in the streets of the city, and far 

 up on the Pilcomayo River. It was equally common a hundred 

 miles east of Asuncion. The stems sometimes climb up among 

 bushes for 6 dm. or more. 



Verbena disseeta, Willd. ; Spreng. Syst. Veg., ii, 750. 



Asuncion (219). December-January. = Balansa 1025. 



A trailing Verbena with bright lilac flowers and dissected leaves. 

 Not quite so common as no. 51, but still frequently found around 

 Asuncion and by the side of the railway as far as Luque.
