I have examined the Bcandegee 

 specimens without discovering- any 

 characters to distinguish P. nucifera 

 from P. aptera." Orcutt. 

 Wislizeiiia divaricata. 



Greene, Wash biol soc pr 19:130 

 (6 S 1906), describes this as follows: 

 "Glabrous, very widely and loosely 

 branched, the branches from strong- 

 ly divergent to quite divaricate, stout, 

 rigid, uncommonly naked-looking, 

 the scattered foliage sm for the plant 

 and all but the proper cauline Ivs uni- 

 foliolate, the Ifts cuneate-oblong. al- 

 most pungently acute, 1.5-2 cm long: 

 racemes many and elongated: fr 5 

 n.'m wide, the carpels elongated pyri- 

 form. bf^ing constricted just above 

 fhe base, marked longitudinally by a 

 prominent narrow reticulation rather 

 than by crowded and unbroken lines, 

 the summit crowned with a circle of 

 about 5 low tubercles." 



Type locality: Borrego Springs, CD, 

 hern part of SD Co. 



Type: Orcutt. 1492, in USXHb (23

 (6 S 1906), describes this as follows: 



"Wish'zpn'a refracta Greene, Fl. Fr. 

 not of Engelm- 



"Stout, much branched, the 

 branches elongated, sparingly leafy, 

 copiously floriferous, minutely sca- 

 berulous in lines: leaflets commonly 

 oval, obtuse or subtruncate. mucron- 

 ulate, sometimes narrower and acute, 

 scaberulous along the midvein be- 

 neath: carpels short, usually obovoid 

 i-ather than pyriform, the longitudinal 

 lines or ribs coarse but low and not 

 very salient, somewhat broken into 

 an obscure reticulation at summit 

 and there, as it were, angled by 4 or 

 5 coarse and low tubercles. 



"Interior of California, in dry. 

 sandy soil from about Tulare north- 

 ward to Sacramento: abundant about 

 Lathrop: totally distinct from the 

 Texan W. refracta." 

 Ptelea brevistylis. 



Greene, CNH 10:73 (16 Jl 1906), 

 describes th : s as follows: "Twigs 

 and branches for two seasons dark 

 reddish brown, sparsely puberulent, 

 not rugulose but roughened with a

rather close tuberculaticn; leaflets 

 of a dull light green, ovate to ob- 

 long lanceolate, 5 cm- long, in age 

 glabrate, doubtless pubescent when 

 young, the margins lightly crenulate: 

 samaras large and with broad thin- 

 nish wing, the outline usually 

 round-obovate, but in some nearly 

 orbicular, the length of the largest 

 2 cm., the breadth toward the sum- 

 mit 1.8 cm.; body of the fruit large, 

 round-obovate, very obscurely and 

 irregularly rugose, somewhat pubes- 

 cent, strongly gland-dotted, very ec- 

 centric, its summit nearly or quite 

 styleless and the win?: thin, deeply 

 emarginate. or obcorlate, the almost 

 sessile stigma 'n the notch, the bass 

 of the winr merely subcordate and 

 the stipe long. 



"Of this shrub. singular amon^ 

 California species cf Ptelea by its 

 large fruit with broad win?-, wh'ch is 

 subcordate at base and nearly obcor- 

 date at summit, only a single speci- 

 men has been seen, and that imper- 

 fect as to foliage, but with a fine 

 cluster of fruits. It was collected by 

 G. R. Vasey in 1875, in what part of 

 the State it is impossible to ascer- 

 tain. 



"It is unmistakatlv Calif ornian by 

 '-he peculiar hue and venation of fol-
