Horticultural Dictionary - Abscission

The normal separation of flowers, fruit, and leaves from plants.

Horticultural Dictionary - Allelopathy

Suppression of growth of a plant by a toxin released from a nearby plant of the same or another species.

Plants have two different types of transport tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots. Plants have adaptations to reduce excessive water loss.

Xylem and phloem

Plants have transport systems to move food, water and minerals around. These systems use continuous tubes called xylem and phloem.

Xylem

Xylem vessels are involved in the movement of water through a plant from its roots to its leaves. Water:

Is absorbed from the soil through root hair cells
Is transported through the xylem vessels up the stem to the leaves
Evaporates from the leaves (transpiration)

Phloem

Phloem vessels are involved in translocation. This is the movement of food substances from the stems to growing tissues and storage tissues.

Xylem and phloem - Higher tier

Xylem vessels consist of dead cells. They have a thick, strengthened cellulose cell wall with a hollow lumen. On the other hand, phloem consists of columns of living cells.

Horticultural Dictionary - Vascular

Any of various plants, such as the ferns and seed-bearing plants, in which the phloem transports sugar and the xylem transports water and salts.

Horticultural Dictionary - Family

Genera are grouped into larger entities called families, some of which are easily recognised, others less so. Although families may appear at first to be of only academic interest, knowledge of the family to which an unknown plant belongs is the springboard to identifying it, and for the gardener, it can give an indication of the conditions required for successful cultivation.

The majority of families have always had names ending with the same group of letters, -aceae, and based on a genus within the family. This neatly distinguishes family names from genera and other plant groups. However, there are eight families with very well-known names which do not conform to this pattern. While it is perfectly acceptable to continue to use these names, the modern trend is to use alternative names with -aceae endings and this is what has been adopted in the RHS Plant Finder.

Family names contain plants with similar flowers but a wide variety of growth forms. Knowing the family helps with identification of unknown plants, e.g. Lamiaceae contains many plants with square stems.

Horticultural Dictionary - Genus

Species which share a number of significant features are grouped together to form a genus (plural genera). The characteristics of a genus are often quite easy to recognise, making this perhaps the most generally useful level at which plants can be identified for practical purposes. It is common for a plant to be referred to as, for instance, Malva sp., the sp. being an abbreviation of species and indicating an unidentified species of a particular genus. Genera can vary in size from a single species to over a thousand, depending on their distinctive characteristics. CompareRhodochiton with Rhododendron for example.

Horticultural Dictionary - Species

The basic unit of plant classification is the species (not ‘specie’ – species is both singular and plural in biology) which can be defined as a group of interbreeding individuals producing more-or-less similar offspring and differing from other similar groups by a number of key characters.
