VOL. IV.] Flora of the Cape Region. 399 



between the high mountains and the Gulf of California, but 

 west of the mountains the ground was well soaked by frequent 

 showers, and vegetation was luxuriant. 



The numbers of the list are continuous with those of previous 

 ones. All above 739 are additions to the known plants of the 

 Cape Region. The smaller numbers belong to plants which 

 occur in the previous lists, of which better specimens or fuller 

 material require notice, or lead to rectifications of diagnosis. 



The grasses of the collection have been studied by Prof. F. 

 Lamson-Scribner, and are not incorporated here, and there yet 

 remain a considerable number of species, requiring careful study, 

 which for lack of time could not be made ready for this paper.

 Plants about i m. high, glabrous throughout, excepting a minute 

 glandular pubescence on the margins of the sheaths, some- 

 what glaucous; stems striate : leaves tripinnate, distant; leaflets 

 slender-petiolulate, thin, sometimes 3 cm., but ordinarily less than 

 2 cm. long, green above, glaucous below, spatulate, ovate or 

 obovate, 3-6-, commonl}^, 3-lobed at apex, the lobes entire: 

 panicle loose and spreading somewhat leafy; pedicels elongated, 

 filiform: flowers usuallj^ hermaphrodite: sepals 4, 2 mm. long, 

 oblong-elliptic or oval, purplish, with conspicuous parallel veins: 

 filaments filiform, flexuous, more or less dilated towards the top, 

 in full development exceeding the linear 4-5 mm. long, mucro- 

 nate anthers, ovaries about 5, stipitate; style filiform 6-8 mm. long, 

 strongly papillose on the back, tapering to the extremity, stig- 

 matic nearly the whole length, the thin margin rolled in: heads 

 nodding in fruit, akenes 5-6 mm. long, usually concave on the 

 inner angle, stipitate, tipped by more or less of the base of the 

 style, the flattened sides and back strongly veined and nodulose. — 

 Common at middle elevations in the mountains of the Cape 

 Region. 



This plant is geographically so far removed from the South 

 American type that comparison of specimens may show them to 

 be specifically distinct. 



y 3. Ranunculus abortivus L. var. australis. Lower 



leaves reniform, 3-5 cm. broad, 2-3 cm. long, petals 5-6 mm. 

 long. Perennial, flowering in August. Abundant in wet places
