Question: Which plant is native the the country that is farther south, Eriobotrya or Ruschia?
Context: Luzula spicata is a species of flowering plant in the rush family known by the common name spiked woodrush.  It has a circumpolar distribution, occurring throughout the northern Northern Hemisphere in Europe, Asia, and North America.  It grows in subalpine and alpine climates.  It occurs at low elevations in colder regions, such as tundra; farther south it is restricted mainly to high mountains.  It is a perennial herb forming grasslike clumps of several erect, reddish stems up to about 33 centimeters in maximum height.  The stem is thick and its base is buried several centimeters in the soil where it attaches to the roots.  The inflorescence is an array of several clusters of brown bristle-tipped flowers.  The surrounding bracts and the sheaths surrounding the leaf bases are lined with hairs. Hieracium bolanderi or Bolander's hawkweed is a North American plant species in the dandelion tribe within the sunflower family.  It is found primarily in the mountains of western Oregon and northern California in the United States, although there are reports of the species farther south in the San Bernardino Mountains in southern California and also in Baja California in Mexico. Packera bolanderi is a species of flowering plant in the aster family known by the common names Bolander's ragwort and seacoast ragwort.  It is native to the west coast of the United States from Washington to northern California, where it grows in wet coastal forests and woodlands.  There are two varieties of the species which differ slightly in morphology and habitat occupied; these varieties have been considered separate species by some authors.  The var.  "bolanderi" has thicker leaves, occurs farther south (into California), and occupies more open types of habitat, than does var.  "harfordii".  This plant in general is a perennial herb producing one to three stems up to half a meter tall.  The basal leaves have blades up to 12 centimeters long which are divided into several lobes and borne on long, thin petioles.  Leaves growing farther up the stem are smaller and have more lobes on their blades.  The inflorescence contains several flower heads, each lined with dark green phyllaries.  The head contains many golden yellow disc florets and generally either 8 or 13 yellow ray florets each over a centimeter long.  The fruit is an achene tipped with a pappus of bristles. Thalictrum alpinum is a species of flowering plant in the buttercup family known by the common names alpine meadow-rue and arctic meadow-rue.  It is native to Arctic and alpine regions of North America and Eurasia, including Alaska, northern Canada, and Greenland, and it occurs in cold, wet, boggy habitats in high mountains farther south. Eriobotrya is a genus of flowering plants, mostly large evergreen shrubs and small trees in the family Rosaceae, native to woodland in the Himalayas and East Asia.  The loquat, "E. japonica", is grown for its edible fruit. Primula farinosa, the bird's-eye primrose, is a small perennial plant in the family Primulaceae, native to Northern Europe and northern Asia, and (rarely) farther south at high altitudes in the mountains of southern Europe.  This primrose thrives on grazed meadows rich in lime and moisture. Stellaria longipes is a species of flowering plant in the pink family known by the common name longstalk starwort.  It has a circumpolar distribution, occurring throughout the northernmost latitudes of the Northern Hemisphere.  It grows in a wide variety of habitat types, including tundra and taiga and many areas farther south with subalpine and alpine climates.  It is extremely variable in morphology, its form depending on both genetic makeup and environmental conditions.  It has a widely varying number of chromosomes.  In general, it is a rhizomatous perennial herb forming mats or clumps, or growing erect.  The stems may be short and simple or with sprawling and highly branched.  The linear to lance-shaped leaves are usually 1 to 4 centimeters long and are oppositely arranged in pairs.  The inflorescence bears one or more flowers, each on a short pedicel.  The flower has five pointed green sepals each a few millimeters long.  There are five white petals each divided into two lobes, sometimes shallowly, but often so deeply there appear to be two petals.  The plant is gynodioecious, with some flowers having functional male and female reproductive parts and others being only female. Trillium vaseyi, the sweet wakerobin or sweet beth, is a spring flowering perennial plant which is found only in the southeastern United States, primarily in the southern part of the Appalachian Mountains but with a few populations farther south. Epilobium palustre is a species of willowherb known by the common name marsh willowherb.  This plant has a circumboreal distribution, and can be found farther south in mountainous areas. Ruschia is a genus of succulent plant, in family Aizoaceae, indigenous to the dryer parts of southern Africa.
