FLORA OF THE CAPE REGION. Ill 



2. TiiALiCTRUM, sp. Found with remains of mature 

 fruit which somewhat resembles that of T. Ilernandezii. 

 Common in wet places about the mountain tops. It is 

 probably an undescribed species. 



3. Ranunculus, sp. Past flowering and with only a 

 single mature seed. The radical leaves are long-petioled, 

 entire, round-reniform and doubly serrate, the heads ap- 

 parently small. — Damp places on the summits of the high 

 mountains. 



4. Argemone Mexicana L. — Todos Santos, La Paz, 

 San Jose del Cabo. 



5. Nasturtium officinale R. Br. — Streams of the 

 Sierra de la Laguna. 



6. Sisymbrium crenatum. — Annual, glabrous, 3^-1 

 m, high, branching above; lower leaves triangular-acu- 

 minate, entire or sinuate-dentate, cuneate at base, 2-4 

 cm. long on petioles of nearly the same length, upper 

 leaves linear-lanceolate, entire or sparingly dentate; ra- 

 cemes i>^ dm. long; sepals greenish, the outer ones 

 convex and saccate at base; petals white 5-6 mm. long, 

 spatulate in outline, about 9-lobed, shortly clawed and 

 twice exceeding the sepals; filaments subulate, tomentose 

 at base much shorter than the petals ; stigma capitate ; 

 pod cylindrical, short stipitate, very slender, about 10 

 mm. long, equaling the pedicel, 8-14 seeded; valves in- 

 distinctly i-nerved, seeds in one row, oblong, cylindrical; 

 cotyledons broad, incumbent somewhat enfolding the 

 radicle. 



• This plant differs from the genus in which it is 

 placed by having lobed petals, a peculiarity not common 

 in Crucifera?. Although the genus Dryopetalum rests 

 mainly upon its lobed petals and this character is a dis- 

 tinguishing one of Schizopetalon it does not seem best to 

 make a new genus for this plant, even though slight
