1922] Johnston: Undescrihed Plants Mostly from Baja California 439 



Viscainoa geniculata var. pinnata var. nov. 



Folia pinnis 3-5 pinnatis. 



Type. — San Eaimonda Creek, Baja California, April, 1889, 

 Brandecjee. Sheet no. 109442 in Herb. Univ. Calif. 



Viscainoa genictdata is so constant throughout most of its range 

 that this very pronounced variant deserves some recognition. It has 

 been detected in only a single locality and perhaps represents only a 

 local race. It is of interest as its leaves are similar to those of the 

 near related genus Chitonia. The type collection made at San 

 Raimonda Creek has definitely pinnate leaves which have a rhachis 

 1-3 cm. long ; and 3-5, distinct, spaced, oblong or lance-oblong pinnae 

 12-25 mm. long. A tendency toward the variety is found in Orcutt 

 1344 from Rosario (Herb. Univ. Calif, no. 109445), which has a 

 vigorous shoot on which two leaves are parted, although the rest of 

 the collection has its leaves entire. 



Condalia Parryi var. microphylla var. nov. 



Folia parva, minus quam 1 cm. longa ; f ructu quam eo specie! 

 minori. 



Type. — Las Huevitas, Baja California, May 19, 1889, Brandegee. 

 Sheet no. 80099 in Herb. Univ. Calif. 



Collections made on Cedros Island by Palmer (752) and Brandegee, 

 and one made at Las Huevitas by Brandegee are similar to one another, 

 but differ from the forms of C. Parryi which occur in Alta California 

 in their conspicuoush^ smaller leaves, stouter habit, and slightly 

 smaller fruit. 



Euphorbia dentosa nom. nov. 



Fuphoriia setiloia dentata Engelm. ; Boiss. in DC, Prodr. 1.5':44. 1862. 



Annual; stems very slender. 1-3 dm. long, villous, internodes 15- 

 30 mm. long; leaves opposite, obliquely ovate, rather thin, glabrous or 

 sparsely villous, finely serrate, light green above, glaucous below, 5- 

 14 mm. long, 4-12 mm. wide, petiol&s 1-2 mm. long, stipules subulate ; 

 involucres solitary" or in close clusters, long villous, about 0.9 mm. high, 

 on peduncles 0.5-2.0 mm. long ; glands brownish ; appendages white, 

 lacerate, 0.3 mm. long. 1.0 mm. wide; seeds ashy, prismatic, 1 mm. 

 long, faces transversely wrinkled. 



The plant described briefly above has been referred to as a variety 

 of E. setiloha, but it seems quite distinct from that species, differing in
