The spicate inflorescences contain hundreds or even thousands of flowers, depending on the species. Each flower has a tricarpellate syncarpous gynoecium and 4 to 6 free stamens, in the species studied. No sepals or petals are present. In\n                    <jats:italic>P. marginatum</jats:italic>\n                    the apical meristem of the inflorescence is zonate in configuration and is unusually elongate: up to 1,170 μm high and up to 480 μm wide during the most active period of organogenesis. Toward the time of apical cessation both height and diameter gradually diminish, leaving an apical residuum which may become an attenuate spine or may be cut off by an abscission zone just below the meristem. The active apex produces bract primordia; when each is 40–55 μm high, a floral apex is initiated in its axil. Both bract and floral apex are initiated by periclinal divisions in cells of the subsurface layer. The bracts undergo differentiation rather early, while the floral apices are still developing. The last‐produced bracts near the tip of the inflorescence tend to be sterile.\n                  </jats:p>","journal":"American Journal of Botany","year":null,"id":43759,"datarank":0.8022482894108738,"base_score":2.3978952727983707,"endowment":2.3978952727983707,"self_citation_contribution":0.3596842909197557,"citation_network_contribution":0.44256399849111805,"self_endowment_contribution":0.3596842909197557,"citer_contribution":0.44256399849111805,"corpus_percentile":null,"corpus_rank":null,"citation_count":10,"citer_count":9,"citers_with_citation_signal":8,"citers_with_endowment":8,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":2.3978952727983707,"endowment":2.3978952727983707,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"20810602","pmcid":null,"openalex_id":"https://openalex.org/W4252881223","authors":[],"funders":[{"funder_name":"National Science Foundation","grant_id":"DEB76–108‐A02","title":null}],"total_grants":1,"fwci":0.348,"citation_percentile":0.64169968,"influential_citations":0,"citation_trend":[],"oa_status":"closed","license":"http://onlinelibrary.wiley.com/termsAndConditions#vor","oa_locations":[{"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fj.1537-2197.1982.tb13314.x","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/j.1537-2197.1982.tb13314.x","host_type":"publisher"},{"url":"http://api.wiley.com/onlinelibrary/chorus/v1/articles/10.1002%2Fj.1537-2197.1982.tb13314.x","host_type":"publisher"},{"url":"https://bsapubs.onlinelibrary.wiley.com/doi/pdf/10.1002/j.1537-2197.1982.tb13314.x","host_type":"publisher"},{"url":"https://doi.org/10.2307/2442964","host_type":"journal"}],"fields_of_study":["Piperaceae Chemical and Biological Studies","Plant and animal studies","Plant Parasitism and Resistance"],"mesh_terms":[],"keywords":["Bract","Inflorescence","Biology","Sepal","Petal","Primordium","Botany","Gynoecium","Apex (geometry)","Stamen","Meristem","Pedicel","Abscission","Perianth","Pollen"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life in Land"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-15T03:06:13.286269Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
