This exhilarating book interweaves the stories of two early twentieth-century botanists to explore the collaborative relationships each formed with Yunnan villagers in gathering botanical specimens ...from the borderlands between China, Tibet, and Burma. Erik Mueggler introduces Scottish botanist George Forrest, who employed Naxi adventurers in his fieldwork from 1906 until his death in 1932. We also meet American Joseph Francis Charles Rock, who, in 1924, undertook a dangerous expedition to Gansu and Tibet with the sons and nephews of Forrest's workers. Mueggler describes how the Naxi workers and their Western employers rendered the earth into specimens, notes, maps, diaries, letters, books, photographs, and ritual manuscripts. Drawing on an ancient metaphor of the earth as a book, Mueggler provides a sustained meditation on what can be copied, translated, and revised and what can be folded back into the earth.
Burmeistera fistulosa and B. reclinata, both from the department of Antioquia (Colombia), are here described and illustrated. The first species is similar to B. tomentosula, from which it differs by ...the glabrous surfaces, the petiole 1.4–2 cm long, the lamina elliptic to ovate, the reduced subtending leaves, the calyx lobes 2.5–3.5 x 0.8–1.2 mm, the ventral anthers barbate, and the white, obconic to ellipsoids berries. The second species is similar to B. diazii, from which it differs by the narrowly ovate leaves with 5–6 pairs of secondary veins and higher order veins inconspicuous beneath, the glabrous flowers with calyx lobes 5–9 x 0.6–1 mm, half of the corolla length or less, the barbate ventral anthers, and the white berries suffused with vinaceous lines.
Burmeistera fistulosa y B. reclinata, del departamento de Antioquia (Colombia), son descritas e ilustradas como especies nuevas. La primera de estas especies es similar a B. tomentosula, de la cual difiere por sus superficies glabras, el peciolo 1,4–2 cm largo, la lámina elíptica a ovada, las hojas tectrices reducidas, los lóbulos del cáliz 2,5–3,5 x 0,8–1,2 mm, las anteras ventrales barbadas, y las bayas blancas, obcónicas a elipsoides. Por su parte, B. reclinata es similar a B. diazii, de la cual difiere por las hojas angosto-ovadas con 5–6 pares de venas secundarias y venas de orden mayor inconspicuas por el envés, las flores glabras con lóbulos del cáliz 5–9 x 0,6–1 mm, la mitad del largo de la corola o menos, las anteras ventrales barbadas y las bayas blancas con vetas vináceas.
A key is presented to seven genera and fifteen species of hornworts recorded from Colombia. Three species found in Ecuador but not yet in Colombia (Dendroceros crispatus, Phaeomegaceros ...squamuligerus, and Phaeoceros tenuis) are also included in the key.
Se presenta una clave taxonómica para los siete géneros y quince especies de antocerotes registrados en Colombia. Tres especies registradas en Ecuador, pero aún no en Colombia (Dendroceros crispatus, Phaeomegaceros squamuligerus y Phaeoceros tenuis), también son incluidas.
