MID
Common Name Hierony's Aa [Hieronymus Bock German botanist 1498- 1554]
Flower Size .1" [.25 cm]
Found in Salta, Catamarca and Cordoba provinces of Argentina as a small to medium sized, cold growing terrestrial with an erect, strict to slightly flexuous, terete, glabhrous, pale straw yellow stem carrying rosulate, basal, erect, submembraneous, narrowly lanceolate to linear-lanceolate, 3 to 5 nerved, intense green, more or less conduplicate, petiolate base leaves that blooms in the mid winter through summer on an erect, terminal, 6 to 16" [15 to 40 cm] long overall, peduncle, 4.8 to 11.2" [12 to 28 cm] long, provided with laxly adpressed, glabrous, scarious, whitish sheathing bracts, rachis, glabrous, 1.2 to 4.8" [3 to 12 cm] long, compact, many flowered inflorescence with triangular-ovate, long acuminate, margin lightly lacerate-denticulate, hyaline, longer than the ovary floral bracts and carrying emerald green to brown flowers.
" Aa olivacea is similar to A. hieronymi from northern Argentina. Both species display dense spikes of dark green to brown flowers that turn black in old (and dried) flowers, with translucent, whitish floral bracts, lateral sepals spreading and perpendicular to the floral axis, and a globose, slightly inflexed lip. However, A. olivacea is recognized by its elliptic to lanceolate leaves (vs. linear-lanceolate), 60 to 100-flowered spikes, (vs. 7 to 25-flowered spikes), a glabrous rachis (vs. pubescent), olive green to chestnut brown flowers (vs. emerald green to brown), lateral sepals with the margin entire to occasionally minutely erose near the apex (vs. apical margin slightly serrate), petals with the apical margin slightly erose to sinuate (vs. apical margin slightly serrate), an unlobed lip with lacerate to erose margin (vs. obscurely trilobed lip with deeply laciniate margins), and ovary with scarce hairs especially in the distal half (vs. many hairs distributed over almost all the ovary)."
