Cryosophila
''Cryosophila'' is a genus of medium-sized fan palms that range from central Mexico to northern Colombia. Species in the genus can be readily distinguished from related genera by their distinctive downward-pointing spines on the stem, which are actually modified roots. They are known as the "root spine palms". Description ''Cryosophila'' is a genus of medium-sized, single-stemmed (or rarely multi-stemmed) palms with fan-shaped (or palmate) leaves and spiny stems. The stems range in height from , with diameters between . Plants have between five and 35 leaves with elongated petioles. The leaves are often whitish-grey on the lower surface. The whitish flowers are bisexual with six stamens and three carpels. The fruit are white and smooth, with a single seed. ''Cryosophila'' is distinguished from related genera by its long, branched spines which are derived from modified roots. These downward-pointing spines cover the trunk, often quite densely. The genus is one of the few palms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thorns, Spines, And Prickles
In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called ''spinose teeth'' or ''spinose apical processes''), are hard, rigid extensions or modifications of leaves, roots, stems or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals from eating the plant material. Description In common language the terms are used more or less interchangeably, but in botanical terms, thorns are derived shoots (so that they may or may not be branched, they may or may not have leaves, and they may or may not arise from a bud),Simpson, M.

Schippia
''Schippia concolor'', the mountain pimento or silver pimeto, is a medium-sized palm species that is native to Belize and Guatemala. Named for its discoverer, Australian botanist William A. Schipp, the species is threatened by habitat loss. It is the sole species in the genus ''Schippia''. Description ''Schippia concolor'' is a medium-sized, single-stemmed palm with fan-shaped (or palmate) leaves. The stem, which is tall and in diameter, is usually covered by the remains of old, dead leaves (but in areas where fires are frequent the corky bark of the stem may be exposed throughout the length of the stem). Individuals bear six to 15 leaves which consist of a petiole and a roughly circular leaf blade which is about in diameter divided into 30 leaflets. The fruit are white, spherical and up to in diameter. Taxonomy ''Schippia'' is a monotypic genus—it includes only a single species, ''S. concolor''.

Trithrinax
''Trithrinax'' is a genus of flowering plants in the subfamily Coryphoideae of the family Arecaceae. The name is derived from ancient Greek, where ''tri'' means three, and ''thrinax'' trident. It was named in 1837 by Carl Friedrich Philipp von Martius, a German botanist and explorer.Moore, H. E., Jr. 1963. An annotated checklist of cultivated palms. ''Trithrinax'' species are spiny fan palms native to South America. They are resistant to cold, heat, wind, drought, poor soils and other adverse environmental conditions. Seeds germinate fast, but their overall growth rate is distinctly slow.Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press. / Description Common features of ''Trithrinax'' species include: *''Flowers'': Inflorescences, in the order of hundreds of units.

Coryphoideae
The Coryphoideae is one of five subfamilies in the palm family, Arecaceae. It contains all of the genera with palmate leaves, excepting ''Mauritia'', ''Mauritiella'' and ''Lepidocaryum,'' all of subfamily Calamoideae, tribe Lepidocaryeae, subtribe Mauritiinae. However, all Coryphoid palm leaves have induplicate (V-shaped) leaf folds (excepting ''Guihaia''), while Calamoid palms have reduplicate (inverted V-shaped) leaf folds. Pinnate leaves do occur in Coryphoideae, in ''Phoenix'', '' Arenga'', ''Wallichia'' and bipinnate in ''Caryota''. Classification Subfamily Coryphoideae is divided into 8 tribes: * Sabaleae ** ''Sabal'' * Cryosophileae ** ''Schippia'' ** '' Trithrinax'' ** ''Zombia'' ** ''Coccothrinax'' ** ''Hemithrinax'' ** ''Thrinax'' ** ''Chelyocarpus'' ** ''Cryosophila'' ** ''Itaya'' ** ''Sabinaria'' * Phoeniceae ** ''Phoenix'' * Trachycarpeae ** ''Chamaerops'' ** ''Guihaia'' ** ''Trachycarpus'' ** ''Rhapidophyllum'' ** ''Maxburretia'' ** ''Rhapis'' ** ''Livistona'' ...

Coccothrinax
''Coccothrinax'' is a genus of palms in the family Arecaceae. There are more than 50 species described in the genus, plus many synonyms and subspecies. A new species (''Coccothrinax spirituana'') was described as recently as 2017. Many ''Coccothrinax'' produce thatch. In Spanish-speaking countries, ''guano'' is a common name applied to ''Coccothrinax'' palms. The species are native throughout the Caribbean, the Bahamas, extreme southern Florida and southeastern Mexico, but most of the species are known only from Cuba. Description ''Coccothrinax'' is a genus of small to medium-sized, fan palms with relatively slender stems and 8 to 22 palmate leaves. The stems are initially covered by fibrous leaf sheaths. These break down into a network of fibres or spines, eventually leaving a bare trunk covered with leaf scars. The undersides of the leaflets are often silvery-grey; this is reflected in the common name "silver palm", which is given to many species of ''Coccothrinax''. The b ...

Zombia
''Zombia antillarum'', commonly known as the zombie palm, is a species of palm tree and the only member of the genus ''Zombia''. It is endemic to the island of Hispaniola (both the Dominican Republic and Haiti) in the Greater Antilles. Usually found in dry, hilly areas of northern and southern Haiti and the northwest of the Dominican Republic, ''Z. antillarum'' is a relatively short fan palm with clustered stems and a very distinctive appearance caused by its persistent spiny leaf sheaths. Threatened by habitat destruction in Haiti, ''Z. antillarum'' is a popular ornamental species due to its distinctive appearance, low maintenance requirements and salt tolerance. Description ''Zombia antillarum'' is a small palm which grows in dense, multi-stemmed clumps with stems up to tall and in diameter. Individuals bear nine to 12 fan-shaped (or palmate) leaves which are greyish-white on the lower surface. The leaf sheaths remain attached to the stem after the leaf drops o ...

Leucothrinax
''Leucothrinax morrisii'', the Key thatch palm, is a small palm which is native to the Greater Antilles (except Jamaica), northern Lesser Antilles, The Bahamas and Florida and the Florida Keys in the United States. Until 2008 it was known as ''Thrinax morrisii''. It was split from the genus ''Thrinax'' after phylogenetic studies showed that its inclusion in ''Thrinax'' would render that genus paraphyletic. The generic name combines ''leuco'' (in reference to the whitish colour of its flowering stalks and the undersides of its leaves) with ''thrinax''. Common names ''Leucothrinax morrisii'' is known as the "Key thatch palm" or the "brittle thatch palm" in the United States. In Anguilla it is called the "broom palm" or "buffalo-top", in The Bahamas, ''miraguano'' in Cuba and ''palma de escoba'' in Puerto Rico. Other common names include "small-fruited thatch palm", ''yaray'', ''pandereta'', ''palma de petate'', ''palma de cogollo'', ''guano de sierra'', and ''palmita''. Desc ...

Thrinax
''Thrinax'' is a genus in the palm family, native to the Caribbean. It is closely related to the genera ''Coccothrinax'', ''Hemithrinax'' and ''Zombia''. Flowers are small, bisexual and are borne on small stalks. Taxonomy In the first edition of ''Genera Palmarum'' (1987), Natalie Uhl and John Dransfield placed the genus ''Thrinax'' in subfamily Coryphoideae, tribe Corypheae and subtribe Thrinacinae. Subsequent phylogenetic analyses showed that the Old World and New World members of Thrinacinae are not closely related and as a consequence, ''Thrinax'' and related genera were transferred into their own tribe, Cryosophileae. In 2008, '' Leucothrinax morrisii'' (formerly ''T. morrisii'') was split from ''Thrinax'' after phylogenetic studies showed that its inclusion in ''Thrinax'' would render that genus paraphyletic In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its desce ...

Sabinaria
''Sabinaria magnifica'' is a species of palm tree and the only member of the genus ''Sabinaria''. Native to the Darién Gap on the border between Colombia and Panama, it grows from tall with large, deeply-divided leaf blades. It has been described as "striking", "spectacular" and "beautiful" by taxonomists. Although known by local mule drivers, it was first collected in April 2013 by Saúl Hoyos, and described scientifically by Colombian palm experts Gloria Galeano and Rodrigo Bernal who named the genus ''Sabinaria'' after their daughter. Despite being locally abundant, the limited range occupied by the species makes it vulnerable to habitat destruction. Description ''Sabinaria magnifica'' is a single-stemmed palm tree with palmately-compound leaves. The trunk is tall and in diameter. Leaves are borne at the end of a long petiole; the combined length of the leaf sheath and petiole averages . Trees bear 20 to 35 leaves which are between in diameter. The leaves of ''S. ...
