    There is much confusion about this species. To my knowledge, this is a true juergensii; small plant with needle like leaves with a relatively large flower.

    Here is a plant that I purchased as Maxillaria juergensii, which it is not. It has thick leaves, and relatively small flowers. I believe this is Maxillaria pumila.

    I have a Max. juergensii and it looks exactly like the one in your first pictures. I too, have both minuta and pumila which to me look exactly the same.

    Maxillaria minuta and pumila are quite similar, but the growths on this pumila are twice the size of minuta. I'll try and post a comparison shot in the next day or two.

    So, i did some comparison shots, and some digging in the literature. Eric Christenson treats minuta and pumia as separate species. To me, the leaves are a bit different (not as dramatic a difference than I remembered), the lip is more sharply downturned in minuta, and the flowers of pumila are on shorter pedicels and seem to be buried in the flower bract.

    However, Koehler considers minuta and pumila (and funera, pusilla, and spannagelii) as synonyms. I can see merit in both arguments.

    Here is a plant comparison, pumila is in the center and two different minuta clones on either side:

    Here is a closeup of the leaves, minuta on the left, pumila on the right. The leaves of minuta seem more apiculate (sharp) and pumila are more blunt. Plus the leaves of pumila seem narrower overall.

    Here is a closeup of the lip of minuta in profile:

    And a closeup of the lip of pumila in profile:

    Here is a front on of minuta:

    Great comparison, thank you. On your earlier post the M. juergensii has a huge flower for the plant size :clap:

    On a warm sunny day like today, my M. pumila (same as yours) has a delicious and strong fragrance of cloves or mulling spices. Reminds me of Christmas.
