L. Fernald (the other being Alcoceria, Euphorbiaceae, now treated as a synonym of Dalembertia Baillon). Fernald stated that many features of Geocaulon are similar to Nestronia (Santalaceae); however, molecular data clearly indicate that Geocaulon is sister to Comandra.</p> |tables= |references= }}<!-- --><!-- -->{{#Taxon: name=Geocaulon |authority=Fernald |rank=genus |parent rank=family |synonyms= |basionyms= |family=Comandraceae |distribution=North America |reference=None |publication title=Rhodora |publication year=1928 |special status=Endemic |source xml=https://bibilujan@bitbucket.org/aafc-mbb/fna-fine-grained-xml.git/src/84153f6d59a0a91d69695978a64cee7560374f8e/V12/V12_936.xml |genus=Geocaulon |apex prominence=vestigial |cortex architecture or pubescence or relief=smooth |cortex relief=not exfoliating |cymule architecture=3-flowered |exocarp texture=fleshy |flower architecture=staminate |flower duration=caducous |flower reproduction=bisexual |flower shape=campanulate;turbinate |hypanthium fusion=adnate |inflorescence position=axillary |lobe arrangement=alternating |lobe prominence=prominent |nectary prominence or shape=flat |pedicel presence=absent |petal atypical quantity=4;5 |petal coloration=greenish;bronze |petal quantity=5 |petal shape=ovate;triangular |petiole height or length or size=short |prophyllar bracteole position=subtending |pseudodrupe architecture or arrangement or growth form=solitary |rhizome coloration=reddish;dark-brown |rhizome texture=not woody |stigma shape=lobed |style shape=short-conic |whole_organism duration=perennial |whole_organism growth form=herb |whole_organism reproduction=andromonoecious }}<!-- -->[[Category:Treatment]][[Category:Comandraceae]] Templates used on this page: Template:Comandraceae (view source) Template:Treatment/AuthorLink (view source) Template:Treatment/Body (view source) Template:Treatment/Body/Maps (view source) Template:Treatment/ID (view source) Template:Treatment/ID/Special status (view source) Template:Treatment/Publication (view source) Return to Geocaulon.
