superioribus basi lata sessilibus semi-amplexicaulibus ; pedunculo brevi- 

 usculo ; cyma nuda parvula; corollge tubo (lin. 2-3 longo) calycis lobis 



foliatis ; corollae cristis faucialibus prominulis ; nuculis haud angulatis usque ad 

 cicatricem sat magnara deltoideara excavatara muricato-granulatis. — E. helio- 

 tropioides Torr. Mex. Bound, p. 140, oxcl. syn. DC. & pi. Beiiand. E. griseum 

 Torr. in herb. Amsinckuv sp. ? Bentti. PI. Hartw. no. 157. Southwestern 

 Texas to New Mexico and Mexico. Very different from Anfiphytum heliotro- 

 pioides A. DC, with which Dr. Torrey confounded it. (No. 1572 of Wriglit's 

 collection is cited by mistalce or misprint as 1512.) Fruiting calyx densely 

 hispid, little more than a line long, closed, detached by an articulation at full 

 maturity. Scar of the nutlets occupying the lower half of the inner face. 

 Buckley's specimens (the character being of no account) show that this (and not 

 E. Texaiium) is his E. hispidum. 



tf t-f Calycis segmenta linearia, obtusa, setis vahdis hispida, lin. 2-3 longa, 

 fructifera clausa, costa valida incrassata indurata : nucuiie heteromorphae, 

 majores : folia subspathulata. 



E. Texanum a. DC. Subpedale ; floribus in spiels laxis fere aphyllis subses- 

 silibus ; nuculis 3 abortivis, unica fertili niajuscula oblongo-ovata laevi (minu- 

 tissime crebreque puncticulata) cicatrice angustissima infra medium gynobasi 

 parvulae conico-columnari afBxa. — Texas, near Austin, &c., Drummond, Wright, 

 E. Hall. Fruiting calyx smaller and with midribs less thickened than in the 

 next, readily separating by an articulation. 



E. CRASSisEPALUM Torr. & Gray, in Pac. R. R. Expl. 1. c. Spithamaeum ; 

 floribus plerisque folioso-bracteatis breviter pedicellatis ; calyce fructifero valde 

 incrassato ; nuculis 4 fertilibus, 3 muricato-granulatis, quarta majore fere laevi, 

 cicatrice cxcavata ovato-lanceolata — W. Texas and New Mexico to Nebraska 

 and Saskatchawan. The thickened pedicel with fruiting calyx persistent, or 

 very tardily separating by an articulation. 



M- M_ H_ Nuculte (immaturae) a basi fere ad medium gynobasi lato-pyramidatae 

 affixae ; corolla majuscula, limbo lin. 3-4 lato. 



E. KiNGii Watson, Bot. King. p. 243, t. 23. Eastern side of the Sierra 

 Nevada. Mature fruit appears not to have been collected. It may refer this 

 peculiar species to the first section or to the following subdivision. 



* * Pseudo-Myosotis A. DC. : perennia vel biennia, floribus pro genere amplis 

 thyrsoideo-congestis, cristis faucialibus corollae prominentibus fornicatis, stylo 

 saepius elongato, antheris lineari-oblongis : nuculaj triquetrge, angulis acutis : 

 gynobasis pyramidato-subulata. 



•1- Syncarpium depresso-globosum, e nuculis lasvissimis crassis circumscriptione 

 fere semicirculari : corolla tubo brevi lato intus basim versus annulo 10- 

 squamulato instructo : spicae paniculatae demum elongandae. 



E. Jamesii Torr. in Marcy, Rep p. 294. E. multicaule Torr. 1. c, forma his- 

 pida. Myosotis snjfniticosa Torr. in Ann. Lye. N. Y. 2, p. 225. W. Texas and 

 New Mexico to Wyoming.
