21s< June. — Since writing the above, I have had the bene- 

 fit of a day's excursion to the salt-water swamps in this neigh- 

 bourhood ; I was rather successful. I got two species of 

 Rhizophora, one new, distinguished by having the flowers 

 sessile ail along the peduncles like figs, and by the form of 

 the leaves : several species of Bruguieria ; B. gymnorrkiza, 

 and I think four others ; there are two species I suspect con- 

 founded by us under B. gymnorrhiza, one with glabrous petals 

 except a few bristles at their points, the other with them 

 densely ciliate or " woolly along the margin :" perhaps B. 

 cylindrica is one of the others, but I am uncertain, as I have 

 not yet compared Rheede's figure; it seems to me to differ by 

 the number of flowers; the remaining two differ by having 

 what may be called umbels (pendulous) of flowers 2-3-cho- 

 tomous; probably they are not inter se distinct, as their prin- 

 cipal difference consists in the form of the leaves, which may 

 arise from luxuriance or some local cause : they present how- 

 ever a very different appearance when growing side by side. 

 Our generic character of Briiguiera must be amended : add 

 "stamens expanding at maturity with elasticity and scattering 

 the pollen of the enclosed anthers," and delete " woolly along 

 the margin ;" add after anthers *' ovate," those of the new spe- 

 cies being decidedly so. I found no Carallia, but abundance 

 of Liimnitzera, and also a Sonneratia which seems different 

 from S. acida, I met with a new species of Dilivaria with 

 hastate leaves, the broad base and points only being prickly; 

 the calyx is 4-lobed or sepaled and with three bracteas; it 

 grows in rocky soil, banks of the Back-water near the Resi- 

 dency, Quilon ; the roots were in the water. I obtained a 

 species of Dalbergia with short lunulate pods, less than an 

 inch long, but I do not yet know if it be a described species. 

 Some days ago I found a Utricularia very like U. vulgaris; 

 perhaps it may be U. Jlexiiosa, Vahl, or fascicidata, Roxb., 

 but it wants the " horns" to the utriculi : at the same time I 

 detected a Villarsia allied to V. crislata, but with excessively
