﻿42 PLANTS HEERMANNIANjE. 



ance. Umbels 2-3 in each of the upper whorls, scarcely half the length of the leaf, 

 with pedicels half the length of the peduncle and, together with the involucral bracts, 

 somewhat tomentose. Stipe of the staminal crown about the length of its lobes, 

 claws cultriform, erect, as high as the white tips of the connectives. Perhaps a new 

 species ? 



It differs from Nuttall's description of A. macrophi/lla in Gambel's plants by its 

 tomentose pedicels, leaves more approximated, denser umbels and the absence of 

 brown color in its flowers. Grows abundantly in river bottoms. Posa creek, 

 August. 



GENTIANE^E. 



ERYTHRiEA muhlenbergii, Grisel. in D. C. Prodr. vol. ix., p. 60. Our plant is 

 intermediary between K tricantha and K Muhlenbergii, all, probably, being varieties of 

 one species. A very showy and beautiful little plant. Fort Miller, July. 



POLEMONIACE.E. 



GILIA elongatA? Stud, in D. C. Prodr. vol. ix., p. 30. Our plant differs from 

 D.C.'s description by being scarcely puberulent, although the capitula are densely lanate; 

 by having mostly four segments on each side of the leaves and by the tube of the 

 corolla being much exerted. Tullary Valley, August. 



CONVOLVULACEiE. 



CUSCUTA subinclusa, nova species. Flores dense glomerati subsessiles. Calyx 

 subovatus, lobis late ovatis obtusis imbricatis. Corolla tubo cylindrico, limbo patente, 

 deinde, germine aucto fauceque marcescente contracta, sublageniformis. Segmenta 

 ovata, latiora supra basim, dimidia tubi longitudine. Antherae elongatse, sub an- 

 gulis subsessiles, subinclusse. Filamenta antheris breviora. Squamellae marginibus 

 parallelis, maxime ad apicem fimbriate, conniventes. Germen biapiculato-globosum, 

 bistyle. Styli duplo fere germine longiores, subinclusi, subinequales. Stigmata capi- 

 tata. 



Flowers subsessile in dense clusters. Calyx subovate, with broadly oval-obtuse and 

 imbricated lobes. Tube of the corolla cylindrical and afterwards rather lageniform 

 by the increase of the germ and shrinking of the fauces. Lobes of the limb ovate, 

 broadest above the base, half the length of the tube. Anthers subsessile under 

 the dividing angles, subincluded. Filaments shorter than the anthers. Scales 

 parallel-sided, fringed chiefly on the top, connivent. Germ globose, bi-apiculate
