HYDROPHYLLACEAE 
HYDROLEA Vahl 
HYDROLEA ZEYLANICA (Linn.) Vahl Symb. 2 (1791) 46. 
Nama zeylanica Linn. Sp. Pl. (1753) 226. 
Steris aquatica Burm. f. Fl. Ind. (1768) 73, t. 39 f. 3. “Habitat 
Coromandeli in locis aquosis.” 
This is clearly identical with Hydrolea zeylanica (Linn.) Vahl, 
a common and widely distributed species in the Indo-Malayan 
region. The figure is poor, but the description is ample. 
BORAGINACEAE 
TRICHODESMA R. Brown : 
TRICHODESMA ZEYLANICUM (Burm. f.) R. Br. Prodr. (1810) 496. 
Borago zeylanica Burm. f. Fl. Ind. (1768) 41, t. 14, f. 2. “Habitat 
in Zeylona.” 
A common and well-known Indo-Malayan species. It was 
described by Linnaeus three years later under the same bino- 
mial, Mant. 2 (1771) 202. 
VERBENACEAE 
LIPPIA Houstoun 
*LIPPIA JAVANICA (Burm. f.) Spreng. Syst. 2 (1825) 752. 
Verbena javanica Burm. f. Fl. Ind. (1768) 12, t. 6,-f. #2. “Habitat 
in Java.” 
Zapania javanica Lam. Ill. 1 (1791) 59. 
This species is one of doubtful status. The figure ‘is distinctly 
different from the common Lippia nodiflora (Linn.) Rich., which | 
is figured on the same plate by Burman as Verbena nodiflora 
Linn. The only other species of the genus reported from Java 
is Lippia asperifolia Rich. to which Burman’s description scarce- 
ly applies, although H. J. Lam in his recent treatment of the 
Verbenaceae of the Malay Archipelago states: “Probably this 
is the same as L. asperifolia.’” Should this prove to be the case, 
Burman’s specific name will replace Richard’s. 
PREMNA Linnaeus 
PREMNA INTEGRIFOLIA Linn. Mant. 2 (1771) 252. 
Premna serratifolia Linn. op. cit. 253. 
Cornutia corymbosa Burm. f. Fl. Ind. (1768) 132, t. 41, f..1, non 
Premma corymbosa Rottl. & Willd. “Habitat in Zeylona.” 
The two forms characterized by Linnaeus do not appear to 
be distinct. Premna integrifolia Linn. is primarily based on
