 brate in age; leaves of the basal shoots lanceolate, 3-<i mm. long, the cauline 

 iinear-lanceolate, 1-2.5 cm. long; panicle elongated, subcylindrical ; pod large 

 for the genus, depressed-globose^ 2-3 mm. in diameter. (L. minor Man. ed. 6,

 leaves erect, mostly appressed; pedicels short; leafy panicle spiiv-like. (L. 

 juniperina l»icknell.) — Sandy soil, coast of s. Me., extending inland in the 

 Androscogirin and Saco valleys to n. N. H.

 w. .Mass. — Distinguished from L. intermedia by its pyramidal inflorescence 

 and slightly smaller puds.

 glabrous; h'dvf^s all small and very narrow ; flowers mostly on very short pedi- 

 cels, difl'uscly racemose-paniculate ; one or botli the narrow outer sepals exceed- 

 ing the inner ones, tli(» latter strictly 1-nerved; pod subglobose. — Dry sterile
