Pittocaulon
'' Pittocaulon'' is a genus of Mexican shrubs and small trees in the tribe Senecioneae within the family Asteraceae. ''Pittocaulon'' is native to the dry parts of central and southern Mexico. In addition to the strange appearance of these plants, ''Pittocaulon'' is of interest due to the remarkable range of habitats in which the species occur, from dry highland scrub well above 3000 meters, to tropical dry forest in hot country as low as 300 meters and on rocks, often in very steep situations. ''Pittocaulon'' species are conspicuous when they flower at the end of the dry season are popularly called "palo loco" or "crazy tree", because they flower at the very end of the dry season when most other plants are suffering the effects of drought. ; SpeciesDavidse, G., M.

Pittocaulon Praecox
''Pittocaulon praecox'' is the type species for the genus ''Pittocaulon'' and family Asteraceae. This species also has the widest range of the genus. Description It is a deciduous shrub or small tree up to 4 meters high. Its succulent, erect, light gray stems fork like a candelabrum. The glabrous leaves, cordate at the base, are grouped at the upper end of the branches, with petioles up to 17.5 cm long. The entire margins have 5 to 8 acuminate lobes. The inflorescences are grouped into five or six ligule that simulate yellow petals. The fruit is less than 1 cm long and is a dry cylindrical or clavate achene with a pappus of white bristles. Distribution It is a plant native to the semi-arid and temperate zones of central and southern Mexico. Its short roots allow it to grow on thin and uneven soils. In particular, it has found a niche thriving on deposits of extrusive igneous material, such as the Nealtican malpaís and the Pedregal de San Ángel (Coyoacán, Mexico City). The p ...

Senecio Praecox
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senecioneae
Senecioneae is the largest tribe of the Asteraceae, or the sunflower family, comprising over 150 genera and over 3,500 species. Almost one-third of the species in this tribe are placed in the genus ''Senecio''. Its members exhibit probably the widest possible range of form to be found in the entire plant kingdom, and include annuals, minute creeping alpines, herbaceous and evergreen perennials, shrubs, climbers, succulents, trees, and semi-aquatic plants. Plants in this tribe are responsible for more livestock poisonings than all other plants combined. Its members usually contain liver and kidney toxic and carcinogenic unsaturated pyrrolizidine alkaloids in ''Senecio'' and furanoeremophilanes in ''Tetradymia''. A number of species are well known in horticulture. Classification Since the time of Bentham, the "premier systematic botanist of the nineteenth century", considerable efforts have been made to classify and understand the striking morphological diversity in the Se ...

Harold Ernest Robinson
Harold Ernest Robinson (May 22, 1932 – December 17, 2020) was an American botanist and entomologist. Career Robinson's specialty was the sunflower family (Asteraceae) and the bryophytes. He has named or described over 2,800 new species and subtribes, more than one tenth of the number of species in the Asteraceae. This figure is also about one quarter of the number of flowering plants described by Carl Linnaeus. Robinson has written over 650 publications, mainly on the Asteraceae, mosses (Bryophyta), Marchantiophyta, and the long-legged fly family Dolichopodidae (describing over 200 new species and 6 new genera, such as '' Harmstonia'' and '' Nanomyina'') and many other subjects. He received a B.S. from Ohio University in 1955, an M.S. from the University of Tennessee in 1957, a Ph.D. from Duke University in 1960. From 1960 to 1962 as assistant professor at Wofford College (Spartanburg, South Carolina), he became Associate Curator of lower plants at the Smithsonian Instituti ...
