I have examined a collection of March from Jamaica in 1765 deposited at NY.

It is an isosyntype and is mentioned by Grisebach in his original citation of specimens examined. It has small blunt leaves and, as shown by a flowering branch on the right-hand side of the sheet, short inflorescences. The following specimens from Jamaica are good matches for the March collection: Howard & Proctor 13734; Harris 9648; Britton 1099, 1504, 943; Campbell 5736. From other parts of the West Indies are the following specimens which match the Jamaican collections: Cuba (Wright 252; Havard 8; Shafer 418, 1825, 2888, 7864); Bahamas (Brace 4327, 4627, 4676; Wilson 7495; J.& A. Northrop 688; Britton & Millspaugh 5611; Britton & Brace 729); Hayti (Nash & Taylor 1672; Leonard 8703); Dominican Republic (Marcano & Jimenez 5152; Bro. Augusto Lavastre 1582, 1866); Puerto Rico (Britton & Marble 1063; Underwood & Griggs 151, 176; Bro. Alain Liogier 9895); Antigua (Box 1098; Rose, Fitch & Russell 3329); Dominica (A. C. Smith 10321; Fishlock 55; Lloyd 639, 672; Hodge 683); Martinique; St. Thomas (Hornbeck s n). The March collection has broadly campanulate-infundibuliform corollas about 5 mm long. These measurements are relatively small compared with most of the other collections cited, in which the corolla length varies commonly from 6-7 mm. The March collection has a filiform peduncle 3-4 mm long and the inflorescence is 6-12-flowered; in the other collections of the West Indies which are referable to subsp parvifolia the peduncle varies from 4-12 mm in flowering stage, up to IS mm long in fruiting stage, with the number of flowers in an inflorescence varying from 3-8.

There are many specimens within the range of C. alba subsp alba and subsp parvifolia which are transitional between the two in size of inflorescence and number of flowers in an inflorescence as well as in size of leaves. The following collections may be cited to illustrate these collections intermediate in character: Antigua (Rose, Fitch & Russell 3431 has the larger leaves of C. alba subsp alba but the smaller, shorter inflorescences of subsp parvifolia); Hayti (Nash 954 has the longer inflorescences of C. alba subsp alba with 9-16 flowers, but the smaller leaves of subsp parvifolia while Nash & Taylor 1446 has the shorter inflorescences of subsp parvifolia but the long pointed leaves of subsp alba; Ekman 8645 has short- and few-flowered inflorescences of subsp parvifolia but leaves tending toward subsp alba); Puerto Rico (Underwood & Griggs 907 has short- and few-flowered inflorescences of subsp parvifolia, but leaves of subsp alba); Jamaica (Britton 1269 has short inflorescences and small corollas of subsp parvifolia but leaves of subsp alba; Harris 11083 has the type of inflorescence characteristic of subsp alba, but with small flowers and leaves of subsp parvifolia); Cuba (Hno. Leon 1376 has leaves approaching those typical of subsp alba but with the shorter inflorescences of subsp parvifolia, and this type of combination is likewise shown by Britton, Britton & Cowell 12485, Combs 57, and Taylor 213, all from Cuba). From Margarita Island, Venezuela, which partakes of a West Indian flora, the following specimens may be referred to subsp parvifolia: Foldats 3009; Linares 39, while the following, also from Margarita Island, appear intermediate between typical C. alba and subsp parvifolia: Foldats 2721,2892; Linares 148; Domingues 325; Foldats 49.

In annotating material of this group for North American Flora, Standley employed a name, which was never published, which applied to Jamaican specimens referred to both subsp alba and subsp parvifolia. However, he himself changed his annotations from one taxon to another and vice versa, indicating his lack of certainty between the two taxa, which in their extremes are separable.
