be excepted. The singularity of New Holland plants attaches 

 to this species of Phragmicoma in its curious lobules of the 

 leaves. We have seen but two calyces, and these upon 

 the same stem, yet one of them had the bilabiate mouth 

 strongly and distinctly dentate, the other had it quite 

 entire ! 



5. P. ustulata, Tayl. ; caule implexo, nigrescente, procum- 

 bente, basi vage ramoso ; foliis verticalibus, arete imbrica- 

 tis, erecto-patentibus, rotundato-ovatis, concavis, integerri- 

 mis, margine dorsali planiusculo, gibboso, ventrali recurvo ; 

 lobulis rotundatis, implicatis, crenulatis ; stipulis obcordatis, 

 lobis subemarginatis. 

 Hab. Philippine Islands. Cuming, Hook. Herb. 



Patches wide, blackish when dry, when moist with a pur- 

 ple tint. Stems about 1 inch long, rather slender ; branches 

 irregular. Leaves with large cells at the base and the central 

 parts. The fruit has not been observed. This may be com- 

 pared with P. polycarpa, Nees ; the leaves, however, are more 

 erect, wider, and their central cellules much larger, the sti- 

 pules so much emarginated as to be nearly obcordate. Dr. 

 Montagne appears to have received a lichen from the 

 Philippine Isles, gathered by Cuming, under the same n. 

 2188. 



18. Lejeunia, Gottsche et IAndb. 

 * Stipulis indivisis. 



I. L. caiyculata, Tayl.; caule implexo, procumbente, sub- 

 ramoso; foliis patenti-recurvis, oblongis, obtusissimis, 

 integerrimis, subdeflexis; lobulis involutis, lanceolatis; 

 stipulis, rotundis, integerrimis ; calyce demum axillari, sub- 

 exserto, obcordato, quadrialato, alis integerrimis, tubo 

 coronato. 



Hab. On Gyrophora spadochroa, Ach., Laurel Mountain, 

 Pennsylvania. T. G. Lea, Hook. Herb.
