Borraginaceee. 



Eritrichium moli.e. Inter Eueritrichium et Knjnitskiam, de- 

 presso-diffusum, caulibus elongatis basi repentibus radicantibus ut 

 videtur pereunans, pilis laxis crebris molliter liirsutum vel potius 

 villosum ; foliis elongato-lingulatis (plerisque bipollicaribus) ; spicis 

 demura elongatis subsolitariis ebracteatis villosis ; pedicellis calycis 

 segmentis lineari-oblongis (i'ructiferis laxis) dimidio brevioi ibus ; corolla 

 alba, limbo lin. lato ; nuculis (liueam longis) trigono-ovatis modice 

 obeompressis doiso vix carinatis grosse areolalo-rugosis iutus superne 

 carinatis, inferne trieute cicatrice ovato-lanceolata gyuobasi brevi- 

 oblongo affixis. — Sierra Valley, California, on alkaline wet flats and 

 borders of ponds, Lemnion, 1874 to 1883, at length with good fruit.. 

 In the Botany of California (i. 528) this is referred to as perhaps a 

 decumbent form of E.' Kiitcjii, of which the fruit was characterized, 

 partly from the original account, and partly from immature nutlets of 

 the present plant, or of E. Kingii ? collected by Lemmon in the same 

 district, but on sandy dunes. The plant now described is very differ- 

 ent from E. Kitigii, of which I have only now seen, through Prof. 

 Eaton's kindness, the mature, muricate-rugose fruit. Evidently the 

 present plant is most nearly related to E. Scouleri, although the scar 

 of the nutlets is wholly introrse. 



Eritriciiium Cooperi. Eueritrichium, Mpsotidea, E. Califor- 

 nico et E. Scouleri alfine, patenti-diffusum e radice ut videtur annua, 

 setis patentissimis brevibus undique hispidum ; foliis subsucculentis 

 fere omnibus alternis linearibus (semipollicaribus) ; caulibus longe 

 racemifloris inter flores brevissime pedicellatos hinc inde bracteatis ; 

 corolliE rotatai limbo 2-3 lin. lato albo in centre flavo ; calyce fructi- 

 fero aporto scsquiliueari profunde 5-partito ; nuculis ovatis trigono- 

 obcompressis obtusiusculis glabris ventre reticulato-rugosulis dorso 

 transverse rugosis, cicatrice brevi sublineari. — Mohave Desert, S. E. 

 California, at Camp Cady, Dr. Cooper, 18G0-G1 ; Rabbit Springs, 

 May, 1882, *S'. D. & W. F. Parish, near to and in water. 



Eritrichium oxygon ujl Krynitzkia, E. muricidato proximum : 

 cyma terminali peduncidata snspius triradiata ; nuculis calycis lobis 

 oblongo-lanceolatis obtusiusculis paullo brevioribus subtriquetris Fago- 

 pyri instar ex ovata subacuminatis, dorso leviter convexo parce muricu- 

 lato, angulis lateralibus acutis, faciebus Itevibus planis, angulo ventrali 

 sulco sat lato gynobasi elongato-subulatas usque ad apicem inserto. — 

 Limb of the rotate corolla 2 lines broad, with conspicuous appendages 

 in the throat. Nutlets a line lonfj. — S. E. California, on hills bor-
