﻿452 Wooton : New Plants from New Mexico 



Philadelphia argvrocalyx. 



Branching shrub, 1-2 m. high, with slender branches, bark red- 

 brown on the younger stems, shreddy on the older ones : leaves 

 opposite, elliptical-ovate, 2-3.5 cm - long, 7-12 mm. broad, acute, 

 contracted into a short petiole, glabrate above, appressed-pubescent 

 and lighter green below, strongly 3-nerved, entire : flowers soli- 

 tary, terminating short leafy branches, bright white, about 3 cm. 

 in diameter : calyx-tube hemispherical, 3-5 mm. in diameter ; limb 

 4-parted, segments ovate, acute, short-acuminate, 4-6 mm. long, 

 the whole calyx with the peduncle densely silvery white, woolly 

 over the outside and at the tips within ; petals 4, obovate, retuse 

 to obcordate : stamens numerous, of several lengths : anthers 

 greenish : styles united ; stigmas linear, slightly longer than styles ; 

 ovary perfectly glabrous : fruit a 4- celled coriaceous pod with nu- 

 merous seeds, inclosed in the persistent woolly calyx. 



Collected on Eagle Creek, in the White Mountains, Lincoln 

 Co., Aug. 14, 1897, in fruit, no. 524, at an altitude of about 7000 

 feet. First collected in flower on Ruidoso Creek in the same 

 mountains, June 30, 1895, at about the same altitude. Also col- 

 lected at Fort Huachuca, Ariz., June, 1892, and July, 1893, by 

 Dr. T. E. Wilcox. 



It is most closely allied to P. micropJiylhts Gray, having about 

 the same sized flowers and leaves, but is easily separated from that 

 species by its calyx. In P. microphylhis the calyx is slightly pu- 

 bescent at the base on the outside, but most of the tube and all the 

 outside of the limb is perfectly glabrous. P. scrpyllifolms Gray 

 has the woolly calyx but its flowers and leaves are not one third 

 the size of those of P. argyrocalyx. 



Lixu.m verxall. 



Annual or biennial (?) herb, 2-3 dm. high with numerous erect 

 stems from a whitish perpendicular root about 1 dm. long : stems 

 slightly curved at the base, branched above, terete, slightly striate, 

 perfectly glabrous : leaves numerous and closely imbricated on 

 the lower part of the stems, more scattered above, 7-18 mm. long, 

 barely 1 mm. wide at the base, linear-subulate, obscurely 1 -nerved, 

 glabrous, bluish-green, lower entire, upper glandular-dentate; 

 stipular glands very small and blackish : flowers numerous, borne 

 on pedicels 5-15 mm. long and apparently opposite the leaves: 

 sepals rather broadly lanceolate, 5-7 mm. long, 1.5-2 mm. W"Je, 

 scarious-margined and glandular-dentate with numerous fine teeth.
