    	Season's Pick 
	
 SEASON'S PICK: We might easily be accused lately of featuring rather humble plants,  arguably ugly (even nasty!) in the case of this season's featured sp., Discocnide mexicana (Liebm.) Chew  (Urticaceae).

         But  after all, we are botanists and we can always find a good story for even the  ugliest of ducklings. This rare plant,  easily mistaken for one of the strongly urticating spp. of Urera [e.g., U. baccifera (L.) Gaudich.], until recently was known in Costa Rica from just one  collection, Bello 828, gathered almost  exactly 25 years ago. Thanks to the work  of José Esteban Jiménez, UCR  student and current holder of the much-coveted title Botanical Explorer Extraordinare [see, e.g., Iridaceae, under  "Leaps and Bounds, in The Cutting Edge 20(2), Apr. 2013], we now have  photos and a second gathering (J. E. Jiménez & Díaz 81) of this unusual  sp., from the same locality as the Bello specimen. As often is the case, our knowledge of this  rediscovery is due to a bit of serendipity: Manual co-PI Barry Hammel, having  glanced at recently mounted specimens waiting to be filed, and having just  dealt with D. mexicana for the purposes  of an illustration for the Manual, noticed the aforementioned misidentification  that might otherwise have left the specimen lost for years in the Urera folder. Even in fruit, the mistake for Urera is understandable; in dried material, the drupelike diaspores (achenes covered  by the accrescent and succulent perianth) of said genus are virtually always  flattened anyway. And yes, we did check through all the Urera folders to make sure no other such  cases of mistaken identity had slipped in. 
         And what else is  so noteworthy about this sp.? Other than  the Monteverde locality being its southernmost extension, the sp. (and monospecific  genus) is apparently distinct from "all the rest of Urticaceae...[for its  achenes that] are very flat, round and disc-like; and the walls are so very  thin and papery that the very slender seed is clearly visible through  them" (Chew, 1965; Bot. Gard. Bull. Singapore 21: 167). The meek (and urticating) will inherit the  earth!
