64 PLANT.E TVRIGHTIAN^. VI. 



calyce cylindraceo-campanulato, tubo turbinato, lobis oblongis tequalibus; petalis 

 unguiculatis lineari-spathulatis cum staminibus stylisque breviter exsertis. — Crevices 

 of rocks, on mountains near the copper mines, New Mexico ; Aug. (a large form, 

 the scapes with the compound panicle one to two feet long), and Oct. (a small form 

 like the specimens gathered in Utah by Capt. Stansbury, the scapes with the more 

 simple panicle a span to a foot high). (1097.) — Petioles either beset with spread- 

 ing hairs, or naked, as are the scapes. Leaves one to nearly two inches wide ; the 

 lobes and teeth short and broad. Scape either leafless or with a few small and 

 sharply toothed or cleft leaves. Pedicels 2 or 3 lines long, minutely granulose- 

 glandular, like the calyx-tube and rhachis, longer than the linear or subulate bracts. 

 Calyx 2 or 3 lines long, at first whitish with the lobes tipped with green, soon 

 turning rose-red or purple. Bracts and pedicels often purplish. 



H. RUBEscENs, Torr. ; var. nana ; scapo subspithamaeo ; floribus parvulis. — With 

 the preceding ; Aug. — A few specimens were gathei'ed of this plant, apparently 

 only a dwarfed state of H. rubescens, with the flowers much smaller, but scarcely 

 developed. I suspect it is the same as the Tiarella ] bracteata of Torrey, in James's 

 Rocky Mountain collection, and therefore Heuchera bracteata. Scringe in DC. Prodr. 

 If it truly prove to be only a depauperate form of H. rubescens, the anterior name 

 ought to give way, on account of its manifest inapplicability. 



H. PARViFOLiA, Nutt. in Torr. ^ Gray, Fl. I. p. 581; Grai/, PL Fendl. p. 54; 

 var. floribus majoribus magis campanulatis. — Mountain-sides near the copper mines. 

 New Mexico. (1098.) — A form with more campanulate flowers, as large as those 

 of H. Americana. The plant connects the section Heucherella with Holochloa. 



Fendlera rupicola, Engelm. 8f Gray, PL Wright, p. 77. t. 5. Rocky banks of 

 the San Pedro, Western Texas, May ; in fruit. Mountains near El Paso, April ; 

 in flower. (1049.) — The petals are puberulent externally (like the inside of the 

 calyx-lobes) ; they are imbricated in aestivation ! — Specimens recently communicated 

 by Lindheimer, in full flower, have their virgate branches loaded with the white 

 blossoms, showing that the plant would be very ornamental in cultivation. 



Philadelphus serptllifolius. Gray, PL Wright, p. 77. Summit of mountains, 

 at Wild Rose Pass, head of the Limpio ; June. (1100.) — Shrub 2-5 feet high, 

 much branched. 



P. serpyllifolius, var. foliis floribusque majoribus.' — Mountain-sides at the 

 copper mines. New Mexico; Aug. (1101.) — The leaves on the more vigorous 

 branches are from half an inch to even an inch in length, and the expanded flowers 

 almost an inch in diameter ; but there is no other apparent dift'erence. 



UMBELLIFERJE. 



Hydrocotyle ranuncdloides, Linn.f. Margin of a creek at Santa Cruz, So 

 nora; Sept. (1102.) 



H. interrupta, il/w/t^. Comanche Spring, Western Texas; June. (1383.) — 

 The California plant referred here is diff'erent. 



BowLEsiA tenera, Sprcng. was found by Mr. Wright in the streets of San An- 

 tonio, Texas ; doubtless introduced.
