compact. It is strikingly different in appearance from typical 

 M. foliosa but the characters separating it are all vegetative. 



8. M. indecora Greene, Bull. Calif. Acad. ii. 152 (1886). 

 Stems from an annual root, sometimes diffuse and forming 



mats 15 cm. or less thick, sometimes erect, slender, and even 4 

 dm. high : leaves very thick and succulent, oblong-lanceolate, pin- 

 nately lobed, the lobes mostly obtuse : involucre 6 or 7 mm. high, 

 imbricated ; inner bracts linear-lanceolate, green ; outer ones said 

 to be purplish : ligules short, greenish-yellow : achenes 5-angled 

 and 2 or 3-striate between the angles : pappus all deciduous.

In the Herbarium of the California Academy of Sciences is 

 a sheet (Acad. no. 49859) indicated as the type sheet of this 

 species and mounted on it are several plants of very different 

 habit but alike in technical characters. Some of these are only 1 

 dm. high and widely branched; others have erect stems as much 

 as 4 dm. high and are not at all matted. But another sheet in the 

 California Academy Herbarium (Acad. no. 49858), although 

 labeled by Professor Greene as the type of one of his unpub- 

 lished species, is undoubtedly the one from which the description 

 of M. indecora was drawn, the specimens being all matted and 

 only 6 to 10 cm. high, the largest forming a mat 17 cm. in diameter. 

 The label reads "Island of Santa Cruz, * * * Rocky islets 

 and promontories, Edw. L. Greene, July and August, 1886." 

 The San Miguel specimens are low and compact. 68 The species 

 is best distinguished from M. foliosa by the size and character of 

 its involucres.

 incanus Nutt., Trans. Am. Philos. Soc. ser. 2, vii. 435 (1841). 

 Malacothrix succulenta Elmer, Bot. Gaz. xxxix. 44 (1905). 



Stems several from a strong perennial root, somewhat woody 

 below, commonly 3 dm. or less high : herbage covered with matted 

 white wool when young, glabrate in age : leaves 5 to 10 cm. long. 



es The two sheets mentioned above were examined before the recent San 

 Francisco fire. It is hoped that they are among the types rescued by Miss 

 Eastwood.
