thirteen, subequal, in three distinct decussate series, broadly 

 ovate to orbicular, minutely erose, thickish, transversely rough- 

 ened on the outer surface, very dark and shining purple : in 

 the staminate flowers the anthers about thirty, globose, sessile, 

 borne in two crowded rows upon the shaft of the staminal 

 column, of which the upper expanded portion is convex, and 

 minutely papillose over its entire surface, the papillae upon 

 the edges being slightly more prominent ; a rudimentary 

 ovary (?) is represented by a narrow central cavity in the base 

 of the column: in the pistillate flowers ovary inferior, three 

 to four angled, but with no regular placenta, the ovules being 

 distributed in small isolated groups over the entire inner sur- 

 face; style scarcely any, the stigma large, hemispherical, um- 

 bonate.— Occurs on small branches of Bauhinia lunarioides 

 Gray; collected by C. G. Pringle in the Sierra Madre near 

 Monterey, June 30, 1888. 



^ This species considerably resembles in size and form A- 

 Blanchetii Gard. of Brazil, also parasitic on a Bauhinia. In 

 the latter, however, the bracts are described as fimbriate-ciliate 

 on the margms, while in A. globosa they are at most minutely 

 erose. furthermore the ovules of A. Blanchetii, according to 

 Sir Joseph Hooker, > are crowded over the whole surface of the 

 ovary, while in A. globosa they occur in rather small isolated 

 groups. The single staminate flower of A. globosa, which 

 was found in the material investigated, occurred upon the 

 same branch with many pistillate flowers. Although a con- 

 siderable number of flowers of A. Pringlei were examined, all 

 proved to be fertile. The ■ 'thallus " of A. Pringlei, investigated 

 by cutting sections of the infested branches of Dalea, appears 

 at the t.me of flowering to consist of dense, isolated, more or 

 less wedge-formed masses of tissue, extending not only 

 through the cortex but to a considerable depth along the 

 medullary rays into the woody tissue of the host
