Prunus ilicifolia as this one does not always have the holly like leaves and the fruit is black not red like the species.
Heres what I have been able to come up with to distinguish these 2 closely related species:
Las Pilitas Nurseries suggests that its very unlikely to find true P. lyonii, most are hybrids.
P. lyonii has larger leaves, up to 5" and mostly entire (no teeth) mostly flat without rolled over margins, thinner and a longer petiole as well as longer inflorescences, up to 5" long.
Prunus laurocerasus is the type species for the subgenus Laurocerasus or the cherry laurels. Others in this group include P. ilicifolia, P. ilicifolia lyonii, P. laurocerasus, P. lusitanica, P. carolinana. They all have flowers that look and smell like these.
P. lusitanica has narrow long leaves with nice teeth, and very long inflorescences.
P. laurocerasus has very wide leaves, except the dwarf cultivars like 'Otto Luyken'.
P. carolinana has smaller leaves and the shortest inflorescences, about 1-2" maximum.
