230 MR. J. BALL ON THE FLORA. OF NORTH PATAGONIA 



Fruticulus ramosissinras ; foliis (saltern superioribus) sessilibus, 

 lineari-lanceolatis, utrinque attenuatis, margine subintegerrimo 

 saepius revoluto, nervo medio prominente," lateralibus obsoletis ; 

 floribus capitatia in spicas brevissimas ramorum lateralium ter- 

 minates congestis ; bracteis floriferis ovatis pubescentibus calyci 

 eubaequilongis ; calyce tubuloso brevissime 4-dentato ; corolla? 

 tubo exserto, paululum recurvato, fauce bilabiato. Ob fructum 

 ignotum inter Lantanam et Lippiam subainbigua, priori tamen, 

 ut videtur, referenda. 



The nearest ally appears to be Lantana Sdlowiana, Link, from 

 which, however, it differs both in habit and structural cha- 

 racters. 



Lippia ltcioides, Steud. Bahia Blanca and North Patagonia 

 (No. 133, G. C-). The leaves, which are very aromatic, are put 

 into the Paraguay tea ; and they are also used medicinally in 

 infusion. The Spaniards call the plant PoUo ; the Araucanian 

 name is Tscho'ike mantuel, meaning ostrich-wood. 



Ltppia seripuioides, A. Gray. Bahia Blanca and through 

 North Patagonia, extending westward to the Cordillera (No. 84, 

 G. C). This is a characteristic species of the Patagonian flora, 

 not extending far beyond, unless perhaps along the flanks of the 

 Cordillera. It is called in Spanish Tomillo del Campo, and in 

 Araucanian Loom. It is used as thyme for flavouring soup &c, 

 and the infusion, which is aromatic with a bitter taste, is used 

 medicinally. From a note by Tweedie on a label in Kew Her- 

 barium, it appears that in his time, nearly fifty years ago, it was 

 sent from the south to Buenos Ay res, and sold by apothecaries. 

 Though long in herbaria, having been collected near Bahia 

 Blanca by Darwin, and on the Patagonian coast by several suc- 

 ceeding travellers, this appears to have been first published by 

 Asa Gray. The manuscript name "L. rubiginosa, Gill.," is affixed 

 to specimens collected near Mendoza by Gillies ; but that specific 

 name has been applied to a very different plant by Schauer in 

 DC. Prod. xi. 



♦Verbena litoralis, Eunth. Tuyu, near Cabo S. Antonio 

 (No. 222, G. C). 



Verbena bonariensis, Z. Valleys of the Eio Colorado and 

 the Eio Negro (No. 224. G. C). Crows in damp ground and 

 by water-courses. Flowers rose-colour or violet.
