42 B. Hayata. 



1200 m, 4 November 1898, E. Langlasse, no. 565 (type, in hb. Gr.). 

 This species shows in its anthers a transition to Ophryosporus. However, 

 the modification of the upper part of the connective into an expanded 

 transparent spongy cushion devoid of vascular tissue is clearly a rudi- 

 mentary form of the terminal appendage. In the true species of Opkryo- 

 sporus, on the other hand, no such rudiment is visible even under the 

 compound microscope. Furthermore, the true Ophryospori have an involucre 

 of nearly equal subuniseriate scales and a naked disk.

In granitic soil of the Sierra Madre. Guerrero, Mexico, altitude 1200 m, 

 7 December 1890, E. Langlasse, no. 589 (type, in hb. Gr.). This species 

 is allied to E. glaberrimum DC., but is glandular-hirsute. It is also near 

 E. Oerstedianum Benth., from which it differs in its hispidulous achenes 

 and narrower involucre, the lowest scales being suborbicular and not at 

 all herbaceous. It is dedicated to the memory of the late Marc Micheli, 

 at one time editor of the interesting exsiccatae of which it forms a part.
