Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2008, Vol 54, Issue 2
Abstract
Euphorbia cyparissias L. is an herbaceous species, wide-spread in the flora of Romania, often founded in plant cultures and roadsides. This report describes the floral morphogenesis in the cypress spurge. The vegetative activity of the shoot apex early ends by forming the inflorescence bracts, which have a different morphology and structure than the nomophylls. Each branch of the dichasial inflorescence ends with a single cyathium. The order of appearance of the cyathium components is as follows: monostaminate male flowers, involucre, nectary glands and female flower.
