    Douglas Justice, in his April blog: April 2015 in the Garden | UBC Botanical Garden, talks about lepidote (scaly-leaved) rhododendrons, or azaleas.
    The only one I have from Douglas's list is Rhododendron augustinii.

    Maybe I was a bit early. But I found others that I think are lepidotes.
    Rhododendron 'Leonard Messel' [edited 2015apr30: I'm adding a photo of the limbs]

    Rhododendron schlippenbachii

    This nice one on the main path that I didn't find the name for [edited 2015apr30: Daniel posted the name - Rhododendron davidsonianum]

    I think this is lepidote, could be corrected, Rhododendron tubiforme.

    Re: April 3, 2015 - April in the Garden - azaleas

    Yes: Lepidotes have lepidia (scales) on them, often these are numerous and quite visible. The only azalea I see in this set is the R. schlippenbachii.

    Re: April 3, 2015 - April in the Garden - azaleas

    Thanks. I misunderstood, thinking the article said lepidotes were azaleas. Is it that azaleas are lepidotes, or are they two different ways of classifying rhododendrons that just happen to sometimes overlap?

    Re: April 3, 2015 - April in the Garden - azaleas

    The way he put it lepidotes are group number three:

    "Cultivated, temperate rhododendrons fit more or less into four main groups: deciduous and evergreen azaleas, lepidote (scaly-leaved) rhododendrons and elepidote (non-scaly-leaved) rhododendrons" - See more at: April 2015 in the Garden | UBC Botanical Garden

    There is a label on the unnamed plant, I photographed it earlier this year. I can't remember the name, though.

    Yes, that's pretty clear in the light of day. Glad I have someone to do my reading for me.

    I'm needing a lot of propping lately. Maybe if we got some sleep it would help. What are we doing up at 12:30am?

    We're sitting here taking this thread off topic, that's what we're doing.

    Great, thanks Daniel. That's one Douglas mentioned as being visit-worthy this month.

    Here are more on the theme from the April blog. I made it back to the garden in April (yesterday), and though it's May now, there are still flowers on these plants.

    I think I've got the idea now. This posting should just be azaleas.

    This is supposed to be an evergreen azalea, though I'm surprised to see that: Rhododendron mucronatum var. ripense

    These are deciduous azaleas:
    Rhododendron molle, mentioned in the blog as the classic Japanese deciduous azalea

    Rhododendron canescens, in the Carolinian Garden, with quite a variation in colouring

    Rhododendron prinophyllum, from Quebec

    Rhododendron vaseyi, from North Carolina

    R. schlippenbachii, from the first posting, is also in this group.

    Still more on the theme from Douglas Justice's April blog, this time
    Lepidote rhododendrons.

    From the E.H. Lohbrunner Alpine Garden
    Rhododendron impeditum
    RhododendronImpeditum_20150430_UBCBG_Cutler_P1180098.JPG RhododendronImpeditum_20150430_UBCBG_Cutler_P1180100.JPG

    Rhododendron russatum

    In the Asian Garden,
    Rhododendron augustinii subsp. augustinii
    RhododendronAugustiniiSubspAugustinii_20150430_UBCBG_Cutler_P1180377.JPG RhododendronAugustiniiSubspAugustinii_20150430_UBCBG_Cutler_P1180380.JPG RhododendronAugustiniiSubspAugustinii_20150430_UBCBG_Cutler_P1180387.JPG

    Next to that was a somewhat lighter one with the same name on the tag, but the database shows it as Rhododendron augustinii subsp. augustinii - Form B. I'm not certain now whether the habit photo above shows it on the right.

    Here is a cultivar, Rhododendron augustinii subsp. augustinii 'Peter Kerr'.

    Rhododendron concinnum 'Chief Paulina'

    Rhododendron rigidum, also with a lot of variation in colour, as Douglas mentions.

    I posted Rhododendron davidsonianum in the first posting, but here it is again.

    Still more on the theme from Douglas Justice's April blog, this time the azaleas, Rhododendrum indicum. Looking at these, I thought they were deciduous, but I'm seeing a lot of stuff saying they're evergreen or semi-evergreen.
    RhododendronIndicum_20150626_UBCBG_Cutler_P1200346.JPG RhododendronIndicum_20150626_UBCBG_Cutler_P1200347.JPG

    This one is R. indicum 'Gyoten'.
    RhododendronIndicumGyoten_20150626_UBCBG_Cutler_P1200349.JPG RhododendronIndicumGyoten_20150626_UBCBG_Cutler_P1200350.jpg

    This is next to the steps on Henry, between Fang and Fortune. I'm assuming it's also R. indicum, but I didn't find the tag. There are several on the database as Unverified Cultivar. Of course the one I can't identify is my favourite.
