probably received these specimens from Patrick Browne, but the 

 usual indication in his handwriting is absent. 



PHTLLAXTHrs ULABELLUS, comb. nov. The plant described by 

 Grisebach (Fl. Brit. W. Indies, 84<) as P. tremulus is identical with 

 a specimen in the Linnaean Herbai-ium from Jamaica collected by 

 Browne, named by Linnaeus Croton glahelhim^ and described by him 

 in Amoen. v. 409. This necessitates a change of name. There are 

 good specimens of the same species in Herb. Banks from Jamaica, 

 collected by Wright, and from Philip Miller's Herbarium, named by 

 Solander Croton (jlaheUum L. 



No fewer than three species have been included by Linnaeus under 

 the name Croton (/laheJlum L. In order of date these are : — 



(1) C. (jlaheUam L. Syst. ed. 10, 1275 (May, June, 1759) based 

 on Sloane, Jam. ii. t. 174. f. 1. The specimen is in Herb. Sloane, 

 and is the plant generally known as Croton lucidus L., the' first 

 description of which appears a few lines below on the same page of 

 the Si/ste?na. C. glabellum L. Syst. is therefore a synonym of 

 C. lucidus. 



(2) C. glaheJlum L. Amoen. v. 409 (1760), based on the specimen 

 in Herb. Browne referred to above. 



(3) C. (jlahellum L. Sp. PI. ed. 2, 1425 (1763). LinnjBus's 

 description is based on the plant of the Amodnitates to which a 

 reference is given (i. e., Phyllanthus tremulus). But Linnaeus cites 

 also Brown. Jam. 348, and Sloan. Jam. 139, Hist. ii. 30, t. 174, 

 :ff. 3 & 4 (in error for f. 2). The Sloane specimen (in Herb. Mus. 

 Brit.) is the plant generally known as C. glahellus, and Browne's 

 description may refer to the same species. That Browne is not 

 referring to the specimen in Herb. Browne subsequently named 

 G. glahellum by Linnaeus is indicated by his reference to the plant as 

 aromatic. 



Linnaeus considered Croton to be of the neuter gender and in- 

 variably wrote glahellum. 



Securinega. 



Adelia Acidoton L. (Syst. ed. 10, 1298 (1759)) is based on 

 Acidoton (Browne, Hist. Jam. 355), and is described in the Amodni- 

 tates (v. 411, 383) ; there is a specimen in the Linnean Herbarium 

 from Browne, named by Linnaeus. The plant in question is Securi- 

 neaa Acidothamnus Muell. Arg. in DC. Prodr. xv. pt. 2,451 (1866), 

 {Flueggea Acidothamnus Griseb. in Goett. Nachr. 164 (1865)). 

 Grisebach (Fl. Brit. AV. Ind. 42) cites Browne's plant {Adelia 

 Acidoton L.), which, however, he had not seen, under Acidocroton 

 adelioides Griseb., a totally different plant. Mueller cites Acidoton 

 Browne as a synonym of Securinega Acidothamnus^ but omits refer- 

 ence to Adelia Acidoton L., which he refers to Acidocroton adelioides 

 in his lists of excluded species under Ricinella (p. 732), and Bern- 

 ardia (p. 924), but does not cite it later in his description of 

 Acidocroton adelioides (p. 1042). The name of the species is 

 therefore Securineoa Acidoton.
