NOTES ON JAMAICA PLANTS. 



B\- William Fawcett, B.Sc, & A. B. Kexdle, F.R.S. 



In continuing our work on the Flora of Jamaica, we have found it 

 necessary to describe a few additional species, diagnoses of which are 

 given below. We have added some notes on nomenclature, whicli 

 may be of general interest. Previous notes will be found in Vol. xlvii. 

 3, 122, 263 (1909); Vol. xlviii. lOo (1910); Vol. I. 177 (1912); 

 Vol. li. 123 (1913) ; Vol. lii. 74, 142 (1911). 



Legumixos.e. 



Tephrosia Wallichii Graham in Wall. Cat. n. '564<i) (nomen). 

 Herba basi sublignosa, ramulis glabris aut pubescentibus demum 

 teretibus. Foliola 11-19 cuneato-oblonga, viridia, supra glabrescentia, 

 subtus glauca, pilis albis brevissimis subsericea, l'5-2'5 cm. 1., 'o- 

 lo cm. br. Stipulae lineari-lanceolatse, 5-7 mm. 1. liacemi oppositi- 

 folii, ad 1 dm. L, floribus vel florum 2-3 fasciculis remotis. Flores

 5 mm. 1., unguicula lo mm. 1. Carina alas subaequans. Stylus glaber,

Type in Herb. W^allich in Herb. Kew. 



Brouf/liton ! Palisadoes, Harris 6753 ! — -Dominica, Trinidad, 

 Guiana, India. 



We agree with Mr. J. K. Drummond's note in Herb, Mus. Brit, 

 that this species is distinct from T. purpurea Pers., but can find no 

 published description. 



DoLiCHOS URENS L. Systcma (ed. 10, 1162) is based on Patrick 

 Browne's description of Zoophthalmum (Hist. Jam. 295) and on 

 Plukenet's figure in Phytograp)hia, t. 213. f. 2. There is no specimen 

 in the Linnean Herbarium. Plukenet's specimen in Sloane's Her- 

 barium (vol. xcvii. f. 86) has leaves which are glabrous on both sides. 

 Browne's description states that the corolla has a very large standard, 

 and that the peduncle is "seldom under four or five feet in length." 



Jacquin (Enum. PL Carib. 27, 1760) diagnoses a species D. altis- 

 simus which he distinguishes from D. vrens merely as having "legu- 

 minibus sequalibus," and cites for it Rheede's Hortus malaharicus, 

 viii. t. 36. Kheede's plant is an Old World species characterized, as the 

 plate also indicates, by smooth pods ; it was subsequently^ named 

 D. giganfeus by Willdenow (Sp. PL ed. 4, 1041), who separated it 

 from D. altissimus, which, as Jacquin was dealing onl}^ Avith American 

 species, must have referred primarily to a New World plant. In order 

 to understand clearly what Jacquin had before him, we must refer to 

 the Select. Stirp. Amer. Hist., where he gives full descriptions (with 

 figures) of each species, and also to the Ed. pict., where there are 

 excellent coloured figures. Z>. ureiis Jacq. (Sel. Stirp. Amer. 202, 

 t. 84) is a plant with leaves tomentose beneath, short peduncle, 

 yellow flowers, a spreading erect standard conspicuously shorter than
