areole - small usually rounded bumps on cacti. Clusters of spines grow from these structures.
They are a defining characteristic of cactus plants. (also from Wikipedia)
bulbosa - inflated at the base
cacti - plural of cactus
callus - the protective tissue formed over a wound, for example, at the base of cuttings.
caudex - the swollen water-storage tissue, usually composed of both root and stem of a
caudiciform - possessing a caudex, OR with a swollen stem.
central spine(s) - the spine(s) rising from the center of the areole, usually protruding and
distinct from an outer ring. They are longer and/or colored in most cacti.
corking - gradual ripening of stem from the base upward, producing a bark-like texture.
crested or fasciation - a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus producing flattened, ribbon-like crested form.
CSSA - Cactus and Succulent Society of America. National umbrella organization of which
LACSS is a local chapter.
cv. - cultivar. Used only occasionally now, not as often as in past years.
dioecious - a plant having male and female flowers on different plants.
diurnal - flowers that open during the day.
dormant - plant is alive but not actively growing.
etiolate - (eh-tee-o-layt) to become pale and/or stretch out, altering the natural form of a green plant by reducing or eliminating sunlight. Example: my succulent has become etiolated stretching to reach more sunlight.
glaucous - bluish grey or bluish green in color.
globose - shaped like a globe
glochids - tiny but sharp spines that are painful/annoying when stuck in your skin. Defined by
Wikipedia as 'hair-like spines, generally barbed, found on the areoles of Opuntiod
cacti. Difficult to remove from skin or clothing because of the barbs.'
The HUNTINGTON - The Huntington Library, Art Museum, and Botanical Gardens, a 501(c)(3) non-profit, is a collections-based research and educational institution serving scholars and the general public. Henry & Arabella Huntington drafted the trust document in 1919 that would transform their private estate into an institution for the "advancement of learning, the arts and sciences, and promote the public welfare."

inflorescence - the complete flower head of a plant including stems, stalks, bracts,
example: "My aloe sent up an inflorescence with orange/red flowers."
The Journal - the Journal of the Cactus and Succulent Society of America.
A regular publication by the CSSA.
LACSS - Los Angeles Cactus and Succulent Society
meristem - the tissue in most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Meristematic cells give rise to various organs of a plant and are responsible for growth. It is the circle that surrounds the vascular bundle.
monoecious - a plant having both male and female flowers borne in separate inflorescences but on the same plant.
monotypic - only one species in a genus
monstrose - a mutation of a plant that happens in the primary meristems. The causes range from injury to bacterial or viral diseases. The three most common types of growth mutation are crests, monstrose growth, and variegation.
nocturnal - flowers that open only at night.
offset - a side shoot, or lateral branch, usually at the base, that has a growing tip and can produce a new plant. Also called offshoot or pup.
overpotted - pot is too large for size of the plant.
pistil - female part of a flower.
POM - Plant of the Month. Competition at each LACSS meeting for a succulent and a cactus
as listed in the Cactus Chronicle newsletter and this website.
pubescent - covered with fine, short, short hairs.
San Gabriel - usually refers to San Gabriel Valley Cactus and Succulent Society (SGVCSS),
another local affiliate of cactus and succulent enthusiasts.
sp. - species
spine - a modified leaf. Provides protection and moisture collection functions.
ssp. - subspecies
stamen - male part of a flower.
stigma - the sticky stem of the pistil of the female reproductive system in a plant.
top dressing - extra usually tiny/small size pebbles, glass, pumice, or other type of material put
directly on top of soil or soil mixture of potted plants to enhance appearance. Also can conserve moisture in soil and keep out weeds, etc.
underpotted - plant is too big for size of pot.
var. - variety
variegated - exhibiting different colors as irregular areas or streaks.
winter or summer growers - these genera actively grow only during the season indicated by
their description as either 'winter' or 'summer' growers. For a list of genera in each category, click on Advice link at top of page.
x - cross. Indicates a hybrid plant.
