species. It occurs in no other collection that I know of, yet it was 

 found in a district which has often been botanized over. The peculi- 

 arities of the species are its fleshy leaves, and tetramerous flowers, 

 with the corolla so deeply cleft that it falls into Miers's section Macro- 

 cope. Otherwise it approaches L. vulgare, but it is without hairiness 

 at the base of the filaments. Berry " saline to the taste, but edible." 



The North American species, represented in Dr. Torrey's herbarium 

 and my own, on examination, give the subjoined results.* 



* Ltcia America Bokealis. 



§ 1. Flores majores : corolla infundibulifortni-tubulosa, ultra-semipollicaris (9-10 

 lin. longa, viridula) : calyx laxe campanulatus, usque vel ultra medium 5-fidus, 

 lobis subfoliaceis patentibus ; antheras mucrone deciduo snperatas. Glabra.

Forma a : filamentis et corolla intus glaberrimis. Spec. Fendler, Newberry, &c. 



Forma (9 : filamentis tnboque corollse intus pilosulis (spec. Thurber) vel hirsutis 

 (spec. Fremont e Rio Virgen). 



This difference in respect to the smoothness or hairiness of the filaments and base 

 of the corolla inside, in what is evidently the same species, throws doubt upon the 

 value of that character in the rest of the genus. No other evidence of dimorphism 

 is observable. Mr. jNIiers described the species from the smooth form ; yet he 

 noticed (what I have not detected in Fendler's specimens) some hairs below the 

 insertion of the filaments. The lobes of the calyx (1^ to 2 lines long) are seldom 

 " lineari-acutis " ; they vary from lanceolate to ovate, and are often very obtuse. 



§ 2. Flores mediocres sed breves : corolla semipollicaris vel brevior, limbi rotato- 

 expansi lobis 4-5 tubo mox longioribus. Glabra, foliis carnosis. 



2. L. Cakolinianum, Walt., Michx. — Coast of South Carolina to the Mexican 

 boundary (Texas, Drummond, Coll. 2, 244). I have it not under the numbers of 

 Berlandier cited by Miers. Filaments very densely tomentose-bearded for a short 

 distance just above the insertion. 



§3. Flores minores : corolla 1 - 1-pollicaris, lobis tubo (saepissime multum) bre- 



vioribus. 



* Calyx profunde 5-fidus, lobis tubo suo longioribus corollae angustse apice bre- 

 viter 5-lobse dimidium fere attingentibus : pedicelli nulli vel brevissimi. Pube- 

 rulse, spinosae. 



3. L. MACRODON (sp. nov.) : ramis junioribus pubescentibus ; foliis glabratis 

 spathulato-oblanceolatis enerviis fasciculatis (2-4 lin. longis) ; pedicellis brevis- 

 simis (ad summum sesquilinearibus) ; calycis minutim viscosi lobis anguste line- 

 aribus tubo breviter campanulato (sesquilineali) duplo longioribus ; filamentis ver- 

 sus basin hirsutulis. — California, in the interior 1 Coll. Fremont in Expedition to 

 California, 1849, Herb. Torr. Corolla half an inch long, narrow. Anthers oval- 

 oblong, slightly if at all exserted.
