    I've got two new words for hairiness, not that I know when to use which. Well, I know to use "sericeous" for Neolitsia sericea, which refers to the silky appearance of the flattened hairs.

    And I learned to distinguish Magnolia wilsonii (on the left in the first photo and in the second photo) and M. sieboldii (third photo) by the "villous" hairs on the back of M. wilsonii. There was some talk of pronouncing "Wilson" as "Vilson" to help remember which has the Villi; worked for me - I've totally got it now, helped by also noticing the different leaf shapes when they're side-by-side). It was easier to feel the difference in the two leaves once I got them home and my fingers had dried off.

    This Rhododendron arizelum seedling still has great fuzzy new leaves (I'm not actually seeing "fuzzy" on the Wikipedia list of hairiness terms; I suppose I need to say tomentose).

    More leafy interest: here's Sorbus hemsleyi, trying to look like a Davidia.

    Rhododendron pentaphyllum, in the Alpine Garden.

    This Quercus myrsinifolia near the garden entrance is evergreen, but still has a bed of leaves of various colours surrounding it, with nice new leaves (and plenty of old ones).

    Rhododendron pentaphyllum, Leaves

    I am glad I found a picture of the same Rhododendron pentaphyllum in bloom, it looked very different at the end of April, but leaves already started to change colors to red
