Description
This adventive biennial plant consists of a rosette of basal leaves during the first year, bolting upward during the second year to produce flowers and seeds. Mature second-year plants are about 2-3½' tall. The basal leaves are usually double pinnate with long petioles. In outline, they are up to 10" and 4" across (including the petioles), narrowing gradually toward their tips. Each compound leaf is subdivided into leaflets that are usually pinnate, while the secondary leaflets are entire, cleft, or coarsely toothed. The individual leaflets are rather narrow, providing the compound leaves with a lacy or fern-like appearance. Scattered white hairs often occur along the petioles, or along the margins and lower mid-veins of the leaflets. The round stems of bolting plants are finely ribbed and have scattered white hairs; they are hollow on the inside and branch sparingly. The compound leaves along the stems are alternate and have their petioles enclosed by sheaths. Otherwise, they are similar to the basal leaves in appearance. The flowering stalks are long and largely devoid of leaves, terminating in compound umbels of small white flowers. Each compound umbel has a whorl of green bracts at its base that are pinnatifid with linear segments. The flat-topped compound umbel is about 2-5" across and consists of about 30 umbellets. Each umbellet has a whorl of linear green bracts at its base and consists of about 30 flowers. While the flowers are blooming, their slender pedicels are often white or greenish white. Each flower consists of 5 white petals and 5 stamens, spanning about 1/8" across. However, the central flower of the central umbellet is often reddish purple. There are forms of Wild Carrot where all of the flowers are light pink, light purple, or reddish purple; the latter color is particularly rare. The blooming period occurs from mid-summer to early fall and lasts about 2 months. There is no noticeable floral scent, although the foliage has a slightly bitter carrot-like scent because of the presence of saponins and possibly other chemicals. Each flower produces a single ribbed seed that is ovate in shape. It is flat on one side, but rounded on the other, with white bristly hairs along the ribs. The color of the seeds is variable, depending on their maturity. They are initially light reddish purple, turning green and then greyish brown. As the seeds mature, the compound umbels start to close and assume a shape that is more or less spheroid. They can become detached from the flowering stalks and blow about in the wind. The root system consists of a stout taproot that is white and runs deep into the ground. This plant spreads by reseeding itself.

Pubmed Word cloud

This word cloud is obtained using the tool LigerCat by searching the Pubmed database. LigerCat builds the cloud from the most relevant Medical Subject Headings (MeSH) terms. Each term's relative size indicates how many times it appears in the PubMed search results. Click on a term to access the full LigerCat cloud, with live PubMed search capabilities. LigerCat has been developed for the Biology of Aging Project.

The page may take some time to load since LigerCat is searching the entire PubMed database and sending us the results in real time.

• If there is an error message below, it means that there is no retrievable information available on NCBI
  
• If the number of nucleotide sequences is less than 100, very little genomic work has been done on this species. A respectable number of nucleotide sequences is above 10000.
• Most of the nucleotide sequences may come from three sources:

1. Studies on single genes, where people try to sequence genes such as some specific dehydrogenases important,say, for tannin production
2. Sequences of Ribosomal Internal Transcribed Spacer, whose sequence is used for generating molecular phylogenetic trees to establish species relationships
3. Expressed Sequence Tags (ESTs) which can tell about which genes are present and expressed in the species at a particular time in the given tissue
