Tylecodon buchholzianus is a species of succulent plant in the genus Tylecodon belonging to the family Crassulaceae.
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined.
In botany, succulent plants, also known as succulents, are plants that have some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. The word "succulent" comes from the Latin word sucus, meaning juice, or sap. Succulent plants may store water in various structures, such as leaves and stems. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. In horticultural use, the term "succulent" is sometimes used in a way which excludes plants that botanists would regard as succulents, such as cacti. Succulents are often grown as ornamental plants because of their striking and unusual appearance.
Tylecodon is a genus of succulent plants in the family Crassulaceae, native to southern Africa.
Tylecodon buchholzianus is a shrub reaching a height of about 20–30 cm. It is a winter slow-growing plant, dormant during the summer. The stem is a swollen and thickened caudex with a diameter up to 30 cm and many elongate whitish or grey branches. In the Spring arise almost cylindrical green leaves, about 10 cm long, but the photosynthesis may be granted also by microscopic leaflets on the stem. Flowers are pale pink, have recurved lobes and emerge from tubes on short petioles. Flowering period extends from January to late Spring.
A caudex of a plant is a stem, but the term is also used to mean a rootstock and particularly a basal stem structure from which new growth arises.
