Abstract (en):
A total of 6634 vascular plant specimens deposited in the UCOB Herbarium from Lara state until 2014 were
reviewed in order to improve our knowledge about the flora. The most prominent collectors are Robert Smith,
Hipólito Alvarado, Bolivia Mediomundo, Charles Burandt Jr., José Antonio Casadiego and Alcides Mondragón. 1659 species were recorded in 859 genera and 155 botanical families, accounting for 64.7% of the families, 36.5% of the genera and 11.3% of the Angiosperm species occurring in the country. Families with higher numbers of species were: Leguminosae (181), Poaceae (166), Asteraceae (125), Rubiaceae (95), Euphorbiaceae (65) and Malvaceae (54). Genera with higher numbers of species were: Paspalum (22), Miconia (20), Cyperus (19), Solanum (18), Piper (16), Senna (15) and Tillandsia (14). Of the total species, 308 are new records and four are endemic to Lara state. The most explored regions are: Serranía de Portuguesa, Serranía de Barbacoas, Serranía de Bobare and gallery forest of the Tocuyo River Basin. The most explored county was Morán (26.7 %), followed by Palavecino (18.8 %) and Iribarren (15,6 %), the least explored were Jiménez (3.7 %) and Torres (4.9 %) municipalities.

Los colectores más destacados son Robert Smith, Hipólito Alvarado, Bolivia Mediomundo, Charles Burandt Jr., José Antonio Casadiego y Alcides Mondragón. Se registraron 1659 especies, agrupadas en 155 familias y 859 géneros, representando el 64,7 %, de las familias, el 36,5 % de los géneros y el 11,3 % de las especies de angiospermas totales del país. Las familias con el mayor número de especies fueron: Leguminosae (181), Poaceae (166), Asteraceae (125), Rubiaceae (95), Euphorbiaceae (65) y Malvaceae (54). Los géneros con mayor número de especies fueron: Paspalum (22), Miconia (20), Cyperus (19), Solanum (18), Piper (16), Senna (15) y Tillandsia (14). Del total de especies, 308 son reportes nuevos y cuatro son endémicas para esta entidad. Las regiones mejor exploradas son serranía de Portuguesa, serranía de Barbacoas, serranía de Bobare y bosques ribereños de la cuenca del río Tocuyo.
