Ulmus crassifoliaNutt., the Texas cedar elm or simply cedar elm, is a deciduous tree native to south-central North America, mainly in southern and eastern Texas, southern Oklahoma, Arkansas, and Louisiana, with small populations in western Mississippi, southwest Tennessee, and north-central Florida; it also occurs in northeastern Mexico. It is the most common elm tree in Texas. The tree typically grows well in flat valley bottom areas referred to as cedar elm flats. Its Latin name refers to its comparatively thick (crassifoliate) leaves; the common name cedar elm is derived from the trees' association with juniper trees, locally known as cedars.
Jubaea is a genus of palms with one species, Jubaea chilensis, commonly known in English as the Chilean wine palm or Chile cocopalm, and palma chilena in Spanish. It is native to southwestern South America and is endemic to a small area of central Chile between 32°S and 35°S in southern Coquimbo, Valparaíso, Santiago, O'Higgins, and northern Maule regions.

Ulmus castaneifoliaHemsley, the chestnut-leafed elm or multinerved elm, is a small deciduous tree found across much of China in broadleaved forests at elevations of 500–1,600 metres (1,600–5,200 ft).

The plant was found only on the small island of Nihoa in the Northwestern Hawaiian Islands, growing on rocky outcrops at altitudes of 120–215 m (394–705 ft). It was one of nine species of Amaranthus in the Hawaiian Islands, as well as the only endemic Hawaiian species of the genus. It is now considered extinct.
Hieracium umbellatum, the Canadian hawkweed, Canada hawkweed, narrowleaf hawkweed, or northern hawkweed, is a flowering plant in the family Asteraceae.
Hieracium debile is a forb of genus Hieracium in the family Asteraceae, and was found only in Ecuador, in two separate collections gathered more than a century ago by W. Jameson. Its natural habitat is subtropical or tropical high-altitude grassland at altitudes between 3,500 m (11,483 ft) to 4,000 m (13,123 ft) but the exact location is unknown as the label in the collections says only "In summis alpibus Quitensibus".
Senecio gallicus, an annual plant of the genus Senecio and family Asteraceae, is a species that colonizes isolated habitats with difficult environmental conditions. It is widespread across southern France and the Iberian Peninsula in deserts and xeric shrublands, on steppes and salty dry coastal plains. S. gallicus is playing a predominant role in shaping patterns of genetic structure by presenting models of historical associations among population rather than patterns of ongoing gene flow.
Zelkova abelicea is a species of tree in the family Ulmaceae. It is referred to by the common names Cretan zelkova, and on Crete proper as abelitsia (αμπελιτσιά). It is endemic to Crete. It is found in small numbers and is classified as Vulnerable on the IUCN red list of endangered species.
Hieracium lachenalii, also known as common hawkweed or yellow hawkweed, is a species of plant in the tribe Cichorieae within the family Asteraceae. It is native to Europe but has become established as a weed in Australia and parts of North America. The species was widely known for many years as H. vulgatum, but more recent studies have indicated that the two names represent the same species. The name H. lachenalii was coined in 1802, H. vulgatum in 1819, so the older name is to be used.
Chrysophyllum imperiale is a tropical tree of the family Sapotaceae native to eastern South America. It is currently classified as an endangered species. Its fruits were very much appreciated by the first emperor of Brazil, Pedro I and his son Pedro II, who exported specimens of the tree as an offering to various botanical gardens around the world, including Sydney and Lisbon.
Acer pentaphyllum is a very rare, endangered maple species endemic to southwestern Sichuan in China, at altitudes of 2300–2900 meters.
Gustav Albert Peter was a German botanist.
August Schlickum was a German schoolteacher and naturalist.
Tamarix canariensis is a species of flowering plant in the family Tamaricaceae. It is a shrub or small tree up to 4 m tall. It was previously said to be native to parts of Macaronesia, northern Africa and south-western Europe, but is now considered only to be found in the Canary Islands, the African and European species being Tamarix gallica. It was first described by Carl Ludwig Willdenow in 1816.
Chamaedorea microspadix, or the hardy bamboo palm, is a species of flowering plant in the genus Chamaedorea, native to eastern Mexico. It is remarkably cold hardy for a palm, able to survive occasional frosts down to 20 °F (−7 °C). Its multiple stalks are jointed, reminiscent of bamboo canes. It is dioecious.
Burghard Hein was the curator of the mycology collection at the Botanic Garden and Botanical Museum Berlin-Dahlem and an authority on the Discomycete fungi.
