ceolato-oblongisve parcius argute serratis ; calycis dentibus subulatis 

 rigidis. — L. Europeans var. sessilifoUus, Gray, Man. ed. 5, p. 345. — 

 Pine Barrens of New Jersey, at Atsion, Canby, and Toms River, 

 C. F. Parker, September. 



L. kubellus, Moeneh. Suppl. (1802). Subglaber ; caule laxo 

 suberecto 1 — 2-pedali, angulis obtusiusculis ; foliis ovato-oblongis seu 

 oblongo-lanceolatis medio argute serratis utrinque attenuatis acumina- 

 tis petiolatis ; calycis dentibus triangulato-subulatis baud rigidis. — 

 Presenius in Flora, 1842 ; Bentb. in DC. L. obtusifolius Vabl ? non 

 Benth. : but if so a depauperate form, and probably not from Hudson's 

 Bay: the indications of habitat in the plants of Michaux's collection 

 are not always correct. L. Europceus, var. integrifulius, Gray, Man. 

 L. Arkansanvs, Fresenius, 1. c. ; a puberulent form, with rather 

 broader and less pointed calyx-teeth, the rudiments of sterile stamens 

 varying from Ungulate to linear-spatulate. — Pennsylvania? and Ohio 

 to South Carolina, Louisiana, and Arkansas. 



h— +- Bractea? exteriores acutissimi flores scepius adosquantes : corolla 

 calycem vix superans : stamina rudimentaria filiformia, apice capi- 

 tellata vel clavellata. 



L. lucidus, Turcz. Caule valido 2-8-pedali erecto superne acu- 

 tangulo ; foliis lanceolatis vel oblongo-lanceolatis (poll. 2—4 longis) 

 acutis vel acuminatis grosse argutissinie serratis basi obtusa nunc acuta 

 subsessilibus ; calycis dentibus attenuato-subulatis. 



Var. Ajiericanus : foliis vix lucidis utrinque saspius hirtello-pu- 

 beris ; caule plerumque hirsutiori ; calycis dentibus minus rigidis. L. 

 obltisifolius, Benth. in DC, vix Vahl. — Saskatchawan (Bourgeau, 

 &c.) to Nebraska and Kansas, Fendler, E. Hall. Our plant clearly 

 is not to be separated from the L. lucidus of N. E. Asia, which, again, 

 too much resembles L. australis, in which also the dots of the leaves 

 are unusually large. 



§ 2. Estolonosce, sed rhizomatibus pi. m. repentibus : dentes calycis 

 5, acutissimi, rigidi, corollam suboequantes, fructiferi nuculis longi- 

 ores : bracteoe subulata?, nonnullas flor3s adaequantes. Glabra? vel 

 pubescentes, caulibus acute tetragonis, foliis soepius incisis vel
