Silaum is a genus of flowering plants in the carrot/parsley family, Apiaceae. There are currently ten species placed into the genus, a list of which is provided below. [1]
Plants in the genus Silaum have umbels which are characteristic of plants in the family Apiaceae (they are umbelliferous, "umbel-bearing"); the umbels in Silaus species tend to lack bracts. [2] Silaum species also tend to have a few umbellules (secondary umbels of compound umbels), and these umbellules have several small bracts called bractlets. [2] Remains of dead leaves can often be found at the base of the plant; plants in Silaum are richly branched. [2]
The fruits of Silaum species have a carpophore, [2] a supporting slender stalk for each half of a gape or burst open ( dehisced) fruit [3] - these are common throughout the family Apiaceae; the carpophore is thread or filament-shaped ( filiform). [2] In addition, Silaum fruits are elongated, divided and not flattened. [2] The mericarps (one carpel of umbelliferous fruit) [4] have acute edges and five, rather low ridges. [2] Plants in Silaus also have an oil tube in the fruit, called a vitta [2] [5] - there is one vitta per every ridge of furrow (a vallecula), but are indistinct at maturity. [2] The petals that surround the flowers are yellow. [2]
Silaum was first formally described in 1754 by the Scottish botanist in charge of the Chelsea Physic Garden, Philip Miller; this description was published in his own reference series, The Gardeners Dictionary (abr., ed. 4 (1754)). [2] The etymology of Silaum was not explicitly offered by Miller, who applied a plant name used by Pliny, [6] though it may refer to the mountainous plateau La Sila in southern Italy. [7]
