VI. 



1 



Fendlera rupicola, Engehn. Sc Gray., Pl. Wright. p. 77. t. 5. Rocky banks of 

 tlie San Pedro, Westeni Texas, May ; in fruit. Mountains near El Paso, April ; 

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

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

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

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



PHiLADELniPS SERPYLLiFOLius, Graj/, Pl WrigJit. p. 77. Summit of mountains, 



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

 much branchcd. 



P. SERPTLLiFOLius, var. foUis floribusque majoribus. — Mountain-sides at the 

 copper mines, New Mexico; Aug. (IIOL) — 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 diflerence. 



UMBELLIFER^. 



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



nora; Sept. (1102.) 



IL interrupta, J/mAZ. Comanche Spring, Western Texas ; June. (1383.) 

 The California plant referred here is difl^ercnt. 



BowLi-sLv TENERA, Spreiig. was found by Mr. Wright in the streets of San An 

 tonio, Texas ; doubtless introduced.

calycc cylindraceo-campanulato, tubo turbinato, lobis oblongis sequalibus; petalis 

 unguiculatis Uneari-spathulatis cum staminibus stylisque breviter exsertis. : — Crevices 

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

 thc scapcs with the compound panicle one to two feet long), and Oct. (a smaU form 

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

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

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

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

 sharply toothcd 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 subspithamcco ; floribus parvulis. — With 

 the preceding ; Aug. — A few specimens were gathered of this plant, apparcntly 

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

 developed. I suspect it is the same as the Tiarella 1 bracteata of Torrey, in James's 

 Rocky Mountain coUection, and therefore Heuchcra bractcata, Seringein 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. Sf Grag. Fl. 1. p. 581 ; Gray, Pl. Fendl. p. 54 ; 

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

 New ]Mexico. (1098.) — A form witli more campanulate flowerSj as large as those 



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