Diagnoses of Two New Genera. 



IIESPERALCEA, of the Malvacete. 



Sldalcea § Hesperalcca, Greene, Fl. Fr. 106 (1891). 



Stout and tall perennial, leafy and hispidiilous, with ample 

 angular foliage, and unisexual flowers in short and dense paui- 

 cled spikes. Involucels 0. Stamineal column double ; fila- 

 ments of the outer series more or less united into sets. Style 

 branches stigmatic lengthwise. Carpels 1-seeded but appar- 

 ently dehiscent by a dorsal suture. Cotyledons round-ovate, 



not in the least cordate. 



Wholly incongruous with JIalva, Sldalcea, etc., as to habit 

 and aspect, its cotyledons as they appear in seeding plants 

 now growing under my inspection, prove this sui generis. 

 These organs, in all the genera closely allied to Malva have 

 one peculiar cut, the distinguishing feature of which is their 

 very neatly cordate-rounded lobes at the base. In this type 

 these are not even so much as truncate at base, but are nar- 

 rowed, though very abruptly, to the petiolule. The species is 

 but one, namely, 



malachPlOIDES. Malva malacJiroides, H. & A. Bot. 

 Beech. 326 (1840). Sidalcea malachroides, Gray, Proc. Am. 

 Acad. vii. 332(1868). 



H 



RAMON A, of the Labiatse. 



Greene, Pittonia, ii. 235 (1892). Species of AudiberUa, 



Benth. 



Suffrutescent ; the stout subterete branches very leafy; the 

 leaves opposite, of obvolute vernation. Flowering stems 

 scapiform, far exceeding the leafy branches (4 to 8 feet high).
