  1. This is the "unknown" sp. It was published about 12 years ago. http://www.botanicus.org/primeocr/mbgserv14/botanicus5/b13058551/31753003431209/31753003431209_0481.txt Microgramma fosteri Leon & Beltran (sub-genus Solanopteris) published in Novon 12(4), 2002. Description: a species with dimorphic leaves, long creeping rhizomes and hollow tubers measuring only 1.5- 2 cm in diameter. It differs from other coenosoric (a particular sori shape) species by the presence of laminar scales intermixed among sori (spore receptacles)and slender paraphyses (sterile plant organs) with elongate apical cells possessing clear lumina and thin walls. Habitat/Range: As one can see from the above date, it is a 'relatively' new find. The type specimen was collected in the year 2000 in the Ucayali Region of north-central Peru on the Azul del Biabo(Blue Mountain Range), at an altitude of 1220 m. (4003 ft.) in the cabaceras del Rio Pisque (headwaters of the River Pisque) which eventually flows to the Pacific Ocean through Uruguay to the north west. The whole of the Blue Mountain Range is located on an isolated branch of the eastern cordillera, spread between the geopolitical regions of Huánuco, Loreto, Ucayali and San Martin. Created in 2001 it forms Azul National Forest the largest continually intact high montane forests in Peru and the country’s third largest national park. Its climate is influenced by its latitude and proximity to the inter-tropical convergence zone and altitudes that vary from a high 2,320 m. (7612 ft.) down to only 150 m (492 ft.) It is generally mild and rainy in areas above 400 m (1312 ft.) but hot and humid on the Amazon lowland plain. At heights of 1220 m. (4003 ft.) and above, expect conditions to be cool and wet, yet the entire region is subject to a pattern of dry periods between Jun/Jul to Oct/Nov. There can also be occasional cold winds from frigid mountains to the south known locally as "friaje" when temperatures will drop to as low as 8°C. (46°F.)for several days. The highest mountains to the north and east of the Cordillera Azul constitute a barrier to humidity from the Amazon plain to the east; therefore, in the northeast of the park, forests are markedly drier at varying altitudes.
