Family:Myrtaceae
Description:Distribution and Ecology - Previously known from Suriname and British Guiana, this species can now bereported from Venezuela. V E N E Z U E L A . Delta Amacuro: Sierra de Imataca,Aserradero El Morro, Atabuina, Caiio Arature, 11 Apr 1959 (fr), Buza 321 (herb.7521) (NY). Bolivar: Sierra de Lema, 80 k m S W of El Dorado, elev 700 m, 22Aug 1961 (fr), Steyermark 89407 (MICH).

Discussion:

Superficially this species somewhat resembles Myrcia graciliflora, but in the latter the leaves are short-acuminate or, if the acumen is elongated it is triangular and even at the narrowest part 2-3 m m wide. The caudate-acuminate leaves of M. schomburgkiana, with linear tips often no more than 1 m m wide, are unique as far as I know among the Guiana Myrtaceae.

Berg mentioned neither collector nor type-locality in the protologue of Marlierea schomburgkiana, saying merely "v. in herb. Berol." Presumably the type has been destroyed. I have not been able to locate any other specimens named by Berg. I therefore designate as neotype the following specimen: BRITISH GUIANA. Upper Demerara River, Jemnan 4176 (K; Univ. of Mich. neg. 1000). This specimen bears a note by N. Y. Sandwith, stating that on 24 June 1931 it was "compared with the type in Herb. Mus. Berol.," and that it "agrees well" with the tj^e. The plant is Marlierea schomburgkiana in the sense of Amshoff (Fl. Suriname 3(2): 65. 1951), and in the sense of m y paper (Mem. N. Y. Bot. Gard. 10(1): 88. 1958).
