Plants Collected in Paraguay. 209 



largest I collected 6 cm. long- and 2 cm. broad. The absence of 

 leaves from the upper part of the stem gives the plant a very strag- 

 gling, naked appearance. When the lateral heads occur they are 

 in pairs, and frequently run together so as to appear but one. A 

 head that I measured was nearly 2 cm. in diameter. 



We first named this G. pidchella, Mart., but we are indebted to 

 Mr. N. E. Brown, of Kew, for a revision of the determination. 



Froelicliia laiiata, Moq., 1. c, 422. 



Pilcomayo River (850). December. = Balansa 194*7. 



Herbaceous, with slender, scapose stems, several rising from the 

 same root, 25-35 cm. high. Nearly all the leaves are in a radical 

 tuft, 1 or 2 occurring upon the lower part of the stems. They are 

 oblanceolate, acute at the apex, sloping into a long. petiole, glabrous 

 and opaquely dotted above, lanate beneath, 3-9 cm. long and 8-10 

 mm. wide at the summit. Scapes more or less lanate. -Flowers in 

 terminal spikes, the lower remote ; perianth scarious-bracted and 

 its segments very woolly as in all the species. On the campo near 

 the railroad between Luque and Paragua, 12 or 15 miles northeast 

 of Asuncion.

Clienopodium antlielmiiiticiiiii, L., Sp. PL, 220. 



Pilcomayo River (909 and 1543). January-February. 



Our Guarani peons on the Pilcomayo River attributed great 

 medicinal virtue to the Roman Wormwood, which grows profusely 

 along the banks. I frequently saw them gathering the spikes and 

 stripping the flowers and fruit into tin cups for the purpose of 

 steeping them into tea. 



Chenopodium glaucum, L., Sp. PL, 220.

Fond of salt soil like all its relations, as it was growing only on 

 the borders of a saline pool at the Laguna de las Palmas.
