Malus sieversii in harsh climates unsuitable for "M. pumila", mainly for increased cold tolerance. "Malus sieversii" has recently been cultivated by the United States Agricultural Research Service, in hopes of finding genetic information of value in the breeding of the modern apple plant. Some, but not all, of the resulting trees show unusual disease resistance. The variation in their response to disease on an individual basis is, itself, a sign of how much more genetically diverse they are than their domesticated descendants. Malus sieversii Malus sieversii is a wild apple native to the mountains of Central Asia in southern Kazakhstan. It has
Orsonwelles malus ("Corynocarpus laevigatus"). Orsonwelles malus Orsonwelles malus is a species of spider endemic to Kauai in the Hawaiian Islands. It was described 2002, although the first individual of "O. malus" was collected in the 1890s. With individuals exceeding , it is the largest species in the family Linyphiidae. Females range from 8.93 to 14.07 mm in total length (length of carapace + abdomen) while males range from 8.74 to 10.66 mm. "O. malus" spiders are found in northwest Kauai, in the Alakai Wilderness and Kona Nā Pali areas, at elevations of , where webs are commonly found in the non-native New
