embryonic/larval lymph gland ring gland lymph gland primordium obsolete embryonic cardiovascular gland true FBbt:00005686 fly_anatomy.ontology Obsoleted because I can find no trace of usage of this term in curation or in the literature despite an extensive search. The ontology term originated as 'cardiovascular gland' in the earliest versions of the anatomy ontology (as a simple nested CV circa 1992) with a reference to FBrf0031012 == Rizki, 1978, Ashburner, Wright, 1978-1980 b: 397--452. However, this reference contains no mention of a cardiovascular gland. The two obvious candidates to map this to are the ring gland or the lymph gland (or their progenitors, as this is an embryonic term) as both are associated with the anterior of the dorsal vessel. However, the earliest versions of the anatomy CV also have terms for these. DOS110317 ring gland primordium
