556 Dowell : North American species of Calceolaria 



channeled, puberulent, about equaling the lip; petals glabrous, 

 veiny, the lateral falcate, 4-nerved, the upper oblong, 3-nerved ; 

 connectiles of lower stamens puberulent 



Mexico : Rose & Hough no. 4S51, type. Specimen in the U. 

 S. National Herbarium, collected July II, 1899, at Guanajuato. 



16. Calceolaria sp. 



Specimens of the plant referred to were collected by 71 5. 

 Brandegee, March 2, 1889, on Santa Margarita Island, Lower 

 California, and are preserved in the Gray Herbarium and in his 

 own private herbarium. The specimen in Mr. Brandegee's her- 

 barium is mounted on the same sheet with two others,, all labeled 

 Ionidium linear e, and is designated by the figure 2. 



It does show a general resemblance to broad-leaved forms of 

 Calceolaria verticillata {Ionidium lineare), but it is quite distinct 

 from this on account of its larger flowers with the lower petal 

 twice the length of the sepals. On account of its large foliaceous 

 stipules it is placed in the last group and not with C. stricta nor 

 with C. angustifolia.

 getting access to more and better material.
