The Cutting Edge

Volume XXI, Number 4, October 2014

News and Notes | Leaps and Bounds | Germane Literature | Season's Pick

SEASON'S PICK: Drymaria multiflora Brandegee (Caryophyllaceae) gets the nod for being this season's most misrepresented, seldom-collected, and tiny-flowered bit of green fodder, nevertheless much deserving a photo essay.

Drymaria multiflora Brandegee (Caryophyllaceae) Drymaria multiflora Brandegee (Caryophyllaceae)

Most of the material recently determined in CR to the obscure and seldom-collected Drymaria multiflora turns out in fact to be nothing but D. villosa Schltdl. & Cham., itself easily distinguished (among other reasons) as the only sp. in CR that is with villous pubescence.

Drymaria multiflora Brandegee (Caryophyllaceae)

All three other spp. of Drymaria in CR are virtually glabrous, except for the very densely and minutely glandular puberulence on the pedicels (and occasionaly elsewhere).  See Barry Hammel's Flickr images to compare this season's featured sp. with D. villosa.

Drymaria multiflora Brandegee (Caryophyllaceae)

Drymaria multiflora is perhaps more reasonably to be compared/confused with D. cordata (L.) Wild. ex Schult. in CR, which has similarly sized and shaped leaves, but from which it differs most obviously by its entire (instead of lacerate) stipules and relatively longer petioles. To our knowledge, D. multiflora has beeen collected only twice in CR, first by Alexander Skutch (Skutch 2992, MO) and more recently by Manual co-PI Barry Hammel, whose above photos are vouchered by Hammel & Pérez 26807 (INB).
