I have not seen this collection. Beilschmiedia costaricensis has alternate leaves and fine ramification, but it has relatively coarser ramification than the other species of the san1e phyllotaxis and ran1ification. Additionally, this species is distinguished from them by a combination of the following characters; appressed to spreading pubescence on the terminal buds and twigs, ramification with free veinlets, non-glaucous lower leaf surfaces, glabrous anthers and fruit pedicels not constricted at the base. This species is sometimes misidentified as B. pendula. About the difference between B. costaricensis and B. pendula, see the notes under B. pendula. Most of the collections from Colombia and Ecuador appear to be different from the collections fron1 other countries (and some collections from Colombia) by their having coriaceous leaves, coarser and less raised ramification and a sparsely pubescent pistil. Additionally, the former collections tend to have shorter petioles and larger leaves than the latters. However, differences of the leaf texture and ran1ification size between them are subtle and hard to make a clear separation, and the petiole length and leaf size has no clear gap between thetn. Pubescence on a pistil in the former collection cannot be a distinctive character because the n1ount of indument is very small and can be easily missed. Considering that separating those two kinds of collections and making a new species from the former collections would only create a confusion, I decide to keep them in B . costaricensis. Usually, orientation of indument on the terminal buds and twigs is consistent within a species in neotropical Beilschmiedia species. But the indument of B. costaricensis ranges from appressed to spreading or very rarely to erect. The collections with erect hairs from Costa Rica (Bello 560, Brenes 6605, Haber 6665, 7693, 7721) share the same characters with the other collections of B. costaricensis except for the erect indument, hence I keep these collections in B. costaricensis. However, the collections with erect hairs from 40
Colombia (Cuatrecasas 22220, 22438) has quite dense pubescence on the lower leaf surfaces, which is very unlikely forB. costaricensis. I classified these Colombian collections as "B. costaricensis vel. aff." Four collections from vicinity of El General, Costa Rica (Hartshorn 2159, Skutch 4389, 5158, Stork 3121), are also regarded as "B. costaricensis vel. aff." Although these collections share similar ramification with B . costaricensis, flowers of them have slightly longer tepals and a densely pubescent ovary, and fruits of them have the pedicel constricted at the base. Pubescence of ovary and constriction of fruit pedicel are regarded as characters sometimes inconsistent, so that more material is needed to clarify whether the collections with these characteristics actually represent a new species or the collections are only one of the variations of B . costaricensis. Several collections fron1 Lin16n, Costa Rica (Herrera2418, 2467, Gomez 23614, Pittier 16140, Robles 2027, 2039, Stevens 24491), have the ramification with free veinlets like B. costaricensis, but the ran1ification scarcely raised on the upper surface and the leaves are very large (ca. 30 em long). I decided to leave them as indeterminate because we have only fruiting n1aterial which is not enough for a proper classification. A few of the collections appear to have hollow stems, although it is not certain if they had ants inhabiting inside. There are a few collections from Panama which have the ramification with free veinlets like B. costaricensis, but the ramification almost completely immersed on the upper leaf surfaces (Correa 10237, 11035, Croat 26947,). Additionally, a few collections from Panama have the ramification totally immersed even on both leaf surfaces (Gentry 13789, 14015). I keep all of these collections as indeterminate because more and better material are needed for their proper classification. 8. Beilschnziedia curviranzea (Meissner) Kostermans, Rec. Trav. Bot.
