432 SUPPLEMENT. 



and accrescent, persistent, rarely disposed to be circumscissile at base : nutlets with obtuser 

 wrinkles. Common in California from Sacramento southward, first coll. by Hartweg. 



= = Calyx cleft only to the middle, silky-villous, rufescent only when young, soon fulvous or 

 whitish, only a line and a half long; in fruit little accrescent, connivent over the nutlets, soon 

 circumscissile, leaving a persistent base which surrounds the lower half of the nutlets: plants 

 erect and slender, sometimes attaining 2 feet in height: fruiting spikes slender, elongated and 

 sparsely flowered, simple or geminate, or as if paniculate, bractless: pubescence of the herbage 

 soft and minute, or soft-hirsute or hispidulous on the lower leaves.

 part. E. nothofulvum, Gray, Proc. Am. Acad. xvii. 227. Bothriospermum spec., Benth. PI. 

 Hartw. no. 1873. Common from Washington Terr, to S. California. 



3. Stipitate-fruited species : nutlets straightish but very oblique, carinate on 

 the back ; caruncle continuous with the ventral crest, projecting into a short in- 

 durated stipe : otherwise much as 2. 



P. UTSinus, GRAT, 1. c. 285. Habit rather of P. Torreyi, but imparting no violet stain to 

 paper, depressed and tufted, very leafy, hirsute and hispid with short bristles : leaves short, 

 spatulate or upper lanceolate ; uppermost oblong, accompanying the clustered or at length 

 more scattered flowers and equalling or surpassing them : corolla very small, hardly exceed- 

 ing the calyx : lobes of the latter in fruit only a line long, lanceolate : nutlets delicatelv 

 rugose-reticulate, smooth, the caruncle little projecting. EcJridiocarya ursina, Gray, Proc. 

 Am. Acad. xix. 90. S. California, in Bear Valley of the San Bernardino Mountains, Parish.

P. Cooperi, GRAY, 1. c. Diffusely branched from the base, with sparsely-leaved ascending 

 flowering stems a span to a foot long, more slender, hispidulous : leaves spatulate-liuear to 

 oblong-lanceolate : spikes at length sparsely flowered, sparingly bracteate or above bractless : 

 corolla more conspicuous, with limb 2 or 3 lines broad : nutlets more trigonous and reticu- 

 late-rugose, dentate-muriculate on the reticulations : caruncle more stalk-like and porrect.

 from San Diego to San Bernardino and southward, first coll. by Dr. Cooper. 



4. HYPSOULA. Nutlets (as the name denotes) inserted by a high scar, 

 i. e. between the middle and the apex, ovoid, obliquely incumbent, little obcom- 

 pressed but rather turgid, nearly straight, rounded laterally, neither rugose nor 

 muricate, ventrally carinate only above the round scar, which is attached to the 

 depressed gynobase by a small and soft (when dry rather fragile) false caruncle : 

 coarse and rough-hispid low annuals, much branched ; with oblong or lanceolate 

 leaves, the upper subtending and equalling or exceeding the flower-clusters, 

 which apparently never extend into naked spikes ; the 5-parted calyx open in 

 fruit. -- Anomali, Gray, Proc. Am. Acad. xx. 286. Almost congeneric with 

 Microula of Tibet. 



P. hispidus, GRAY, 1. c. Half a foot high : lower leaves linear-spatulate, upper oblong : 

 nutlets turgid, acute at apex, obscurely carinate on the back, opaque, papillose-granulate, 

 the scar hardly above the middle. Truckee, on the eastern border of California, Mrs. 

 Layne-Curran. 



P. glomer4tus, GRAY, 1. c. Stouter : leaves mostly ovate-oblong : nutlets larger (a line 

 and a half long), less turgid, more oval and obtuse, flatter and not carinate on the back, 

 smooth and somewhat shining, but with obscurely undulate-rugulose surface, the scar be- 

 tween the middle and the apex. Western part of Nevada, between Carson and Virginia 

 City, Mrs. Layne-Curran.
