The Verdigris River is a tributary of the Arkansas River in southeastern Kansas and northeastern Oklahoma in the United States.
 It is about 310 mi long.
 Via the Arkansas, it is part of the Mississippi River watershed.
The Kansas City, Clinton and Springfield Railway, also known as the Leaky Roof Railway, is a now abandoned rail line that ran from Olathe, Kansas, near Kansas City, through Clinton, Missouri, and on to Ash Grove, Missouri, where it tied in with the Kansas City, Fort Scott and Gulf Railway, later the Frisco Railroad.
 A short branch line served Pleasant Hill, Missouri.
 It was founded in 1884, as a subsidiary of the KCFS&G; on February 12, 1885, the railroad was incorporated in Missouri.
 The line was later bought by the Frisco (St. Louis-San Francisco Railway) in 1928.
 After consolidation with the Frisco, the route was deemed redundant to the parallel and better constructed Frisco "Highline".
 Seeking to cut costs, the Frisco chose to abandon the line in 1934.
 Because it ran parallel to the Frisco's Highline, the two railroads intersected at many places.
 Thus, the Frisco chose to consolidate the two lines into one by keeping the track of whichever railroad had the favorable route between these numerous crossings.
 The less favorable sections were then removed.
 Service continued over these portions of the line with a daily except Sunday local until the mid-1970s, when dam construction and bridge fires ended through service on the route between Kansas City and Springfield, Missouri.
 Operating for a while as a North and South branch line, services were cut and the line was, section by section, successively abandoned.
 Although the rails are now gone, traces can be found along Route 7 and Route 13, however along most sections, little remains to be seen.
Xystreurys is a genus of large-tooth flounders with one species, "X. liolepis", found along the Pacific coast of North America from Monterey Bay, California to the Gulf of California and the other, "X. rasile", found along the Atlantic coast of South America from Rio de Janeiro, Brazil to the southern tip of Argentina.
Dracaena mannii Baker or small-leaved dragon tree, is a small to medium-sized tree, though recorded up to 30 m tall with stem to 2 m in diameter in Cameroon and Gabon.
 It occurs from Senegal to Angola along the African west coast, is widespread in tropical Africa and is found along the African east coast from Kenya to Kosi Bay in northern KwaZulu-Natal.
 It prefers lowland, submontane and montane forests which are either moist and evergreen, swampy or on coastal dunes.
 It is also found along forest edges, in clearings and on river banks from sea level to 1,800 metres.
 It is one of some 120 species currently recognised, which occur primarily in Africa and southern Asia with a single vagrant species in Central America.
 The species is named after Gustav Mann (1836–1916), a German botanist, who corresponded with John Gilbert Baker.

 The genus "Ariopsis" has been merged with "Sciades" by some authorities.

Richard de Pilmuir [Pilmor, Pylmore] (died 1347) was a 14th-century bishop of Dunkeld.
 He was a brother of John de Pilmor, bishop of Moray.
 He was precentor of the bishopric of Moray when, following the death of bishop William Sinclair, the canons of Dunkeld held an election.
 This happened in the year 1337.
 The result was disputed.
 Richard's election was challenged by Maol Choluim de Innerpeffray.
 The dispute was taken to the papal court.
 Pope Benedict XII passed the question on to Cardinal Bertrand du Pouget, bishop of Ostia, for judgment.
 In July 1344 the cardinal declared the election of both null and void, but appointed Richard to the bishopric.
 Richard, as bishop of Dunkeld, maintained connections with Moray.
 On 20 October 1345 he is found along with his brother at Elgin Cathedral.
 Along with other Scottish bishops, he signed a letter addressed to the pope asking requesting legitimation of Robert Stewart's marriage to Elizabeth Mure.
 He died sometime in November 1347.
