These specimens were referred to the only species of Anamomis 

 known to grow in the United States, the endemic Anamomis 

 dicrana. The leaves on the twigs collected from sprouting 

 stumps were evidently not t^-pical of the normally developed 

 tree, while those on our only flowering specimens were only 

 partly developed. Last winter, however, I received a branch 

 with fully and normally developed leaves, collected by Mr. 

 Charles T. Simpson in the Arch Creek Hammock. This speci- 

 men revived my interest in the specimens we had collected in 

 previous years; but it was not until April 191 7 that the status 

 of the plant was finally established. One morning in passing 

 Arch Creek while going from Ft. Lauderdale to Miami, Mr. 

 Simpson and I visited the trees Mr. Simpson had discovered in 

 the winter, and fortunately we found one tree in full flower. 

 • The mature leaves and the flowers proved the tree to be different 

 from the previously known Florida species of Anamomis, and 

 also different from any species known from the West Indies. 

 The tree should bear the name of the discoverer of the best 

 specimens, and it may be named and described as follows: 



Anamomis Simpsonii Small sp. nov. A tree 15 m. tall or less 

 with a buttressed trunk when well grown, a smooth bark, and 

 finely appressed-pubescent twigs: leaves numerous; blades nar- 

 rowly obovate, elliptic-obovate, or nearly elliptic, 2.5-6.5 cm. 

 long, acutish, obtuse, or notched at the apex, dark green and 

 shining above, paler and dull beneath, coriaceous, finely glandu- 

 lar-puncate, entire, with rather distant primary straight lateral 

 veins and coarse rather faint (except when dry) reticulations 

 between them, with the branches forming marginal loops, rather 

 slender-petioled : cymes lateral, 3-15-flowered, slender-pedun- 

 cled, the peduncles about as long as the subtending leaves, some- 

 times longer, sometimes shorter, minutely appressed-pubescent, 

 each bearing a pair of small leaf-like bracts at the apex: flowers 

 fragrant, sessile: hypanthium short-obconic, densely silky- 

 strigillose with white hairs: sepals 4, green, paired, two of them 

 orbicular-ovate, two orbicular-reniform, 2-2.5 mm. long, obtuse, 

 punctate, the narrower ones merely ciliolate, not scarious- 

 margined, the Avider ones with erose-ciliolate margins: petals 

 white, concave, 4-5 mm. long, obovate to suborbicular, sparingly 

 punctate, erose-ciliate: stamens mostly 60-70; filaments capil- 

 lary, 5-6 mm. long; anthers globose-didymous, fully 0.5 mm.
