SUPPLEMENTAL NOTE ON H AMELIA. 

 By H. F. Wernham. 



I AM much indebted to the kindness of Dr. N. L. Britton, 

 Director of the New York Botanical Garden, for drawing my 

 attention to the following additional species of Hamelia, a genus 

 with which I dealt in a recent paper (Journ. Bot. 1911, 206). 

 Dr. Britton has been also good enough to present a portion of the 

 type-plant to the National Herbarium. 



H. Brittoniana, sp. nov. Foliis verticillatis pubescentibus, 

 floribus majusculis manifeste pedicellatis corolla superne necnon 

 ampliata.

Frutex ramulis brevissime pubescentibus, foliis verticillatis 

 lanceolatis 7-8 cm. x 2-2-5 cm. superne glabris subtus ferrugineo- 

 pubescentibus utrinque angustatis acutis petiolis ad 1 cm. longis, 

 stipulis subulatis ca. 4 mm. longis, cymis pubescentibus termina- 

 libus floribus plerumque pedicellis ad 1-5 mm. longis, calycis totius 

 4-4-5 mm. longi tubo anguste cylindrico sparse pubescente nee 

 sulcato limbi lobis latissime deltoideis, corollte extus brevissime 

 pubescentis tubo ca. 2 cm. longo sursum ampliato ad 6 mm. lato 

 basi vix ventricoso lobis brevibus latiusculis acutis erectis, sta- 

 minum linearium filamentis 4 mm. complanatis antheris 1-5 cm. 

 longis apice spathulatis basi breviter appendiculatis. 



The affinities of this species are with H. pa^e^is, but it is 

 distinct in the size and shape of the corolla, in the relatively long 

 floral pedicels, and in the shape of the calyx-tube. 



H. EoviROS^ Wernham. I find that this Mexican species, 

 described by me in the paper cited above, is identical with a plant 

 collected by Turckheim in Guatemala, and described by Donnell 

 Smith as a variety of H. patens — var. coronata — in Bot. Gaz. xl. 4. 

 The type number is 8532 ex PI. Guat. &c. quas ed. Donn. Sm. 

 This plant unfortunately escaped my notice at the time when I 

 was examining the genus, but I have no hesitation in maintaining 

 its specific rank. Its relationships, in fact, do not appear to be 

 with H.imtens at all, as witness its glabrate leaves and long calyx- 

 lobes. A co-type of Turckheim's plant, which Dr. Britton has 

 been so good as to place at my disposal for examination has, 

 moreover, a flower with a fully opened corolla. This is of a 

 slender appearance, gradually and slightly widened above, and 

 2-2 cm. long. The pubescence on the inflorescence branches is 

 characteristic in being conspicuously spreading, though short, and 

 ferruginous. The calyx-lobes correspond precisely in shape with 

 those of the type of H. Bovirosce, but they are not revolute.
