Specie experts out there, what is the identifying differences between l. Davidii and l. Lancifolium, please. What would you identify these stems as?
Thanks, much.

I'm not overly familiar with species, but I see bulbils forming on the leaf axils, which would make me think it's lancifolium.

There are a lot of differences between L. davidii and L. lancifolium. The easiest differentiation is the foliage.

L.davidii foliage is narrower and thinner textured. No bulbils.

Yours is L. lancifolium.

L. lancifolium is also pubescent. I've only grown L. davidii for 3 years, but I haven't noticed any pubescence on L. davidii

In general, a good observation, as lancifolium is woolly all over when growth is younger and davidii almost never is. However, depending on which davidii variety, it could be a little misleading to the uninitiated:
