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 hei'bage 

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

 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. ursinus, Gray, 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 delicately 

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

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

 Adj. Lower California, Orcutt. 



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-linear 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. 

 — Echidiocarya Californica, Gray, Proc. Am. Acad. xii. 164, & p. 199. — Lower California, 

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



§ 4. Htpsoula. 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 » 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. glomerdtus, 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.
