species of this section has made it clear that both of them should 

 fall into Plagt'obothrt/s, a genus now shown to comprise a good num- 

 ber of species, and considerable diversity in the form and texture 

 of the caruncle-like body by which the nutlets are attached to the 

 gynobase. 



* * * * Anomali : nuculce rectiusculnp, nee rugosre nee muricat;f , 



medio vel supra medium areolis orbiculatis gynobasis depressre 



adfixap, pseudo-caruncula priemoUi minus persistcnte : herbae (Sierra- 



Nevadenses) diffusfp, ramosissima^, rudes, hispidfp ; caulibus ad 



apicem usque foliatis ; floribus semper glomeratis foliis (superioribus 



latioribus basi lata arete sessilibus) fulcratis ; calycibus o-partitis, 



fructiferis apertis cum pedicellis brevissirais diu persistentibus. 



The first of these species would pass unquestioned for a Plagio- 



bothrys of a coarser sort, with the habit of P. Turreyi and P. ursinus. 



The second, of similar aspect, is more anomalous in the smooth and 



somewhat polished nutlets, with insertion well above the middle. The 



insertion in both is by a small and depressed central umbo, which fits 



into the very shallow round areola on the gynobase, the low margins of 



which are continuous with the soft-fleshy annulus or collar (so soft as 



to become pultaceous in hot water), which goes with the nutlet when 



this falls away, and forms a scale-like caruncle, of variable outline, 



and easily broken up. For both these species we are indebted to the 



same zealous and ?harp-sighted botanist. 



P. nisPiDUS. Semipedalis ; foliis inferioribus lineari- vol angusto- 

 spathulatis, superioribus oblongis (vix senii[)ollicaribus, flores super- 

 antibus ; nuculis turgide ovatis acutis dorso leviter obtuseque carinatis 

 undique subpapilloso-granulatis opacis medio vel paullo supra medium 

 insertis. — Truckee, on the eastern border of California, Mrs. Layne- 

 Curran, 1884. 



P. GLOMi'.RATUS. Yalidior ; foliis latioribus s^ppius ovato-oblongis ; 

 nuculis nitidis fere hevibus ovali-ovatis minus turgidis (paullulum ob- 

 compressis) dorso convexiusculo baud carinatis intus inter medium et 

 apicem insertis. — Western part of Nevada, between Carson and Vir- 

 ginia City, 1883 and 1884, Mrs. Layne-Curran. 



ECniDTOCARYA, reduced to the typical species, E. Arizonica, 

 reverts to the original character in Proc. Am. Acad. xi. 89, and Benth. 

 & Hook. Gen. PI. ii. 854, E. Californica and E. ursina being now 

 referred to a subdivision of Plagiobothrys.
