SPICILEGIA FLOK^ SINENSIS. 227 



I believe this is the most southerly station known for this 

 plant. 



14. Callitriche verna, Linn. (Hegelmaier Monogr. Callitr. t. iii., 

 f. 10.) In oryzetis ins. Danorum, Whampoae, ipse detexi, m. Febr., 

 1861 ; in stagnis Cantonensibus, Martio 1869, invenit Sampson. 



15. Eugenia (Syzygium) Bullockii, sp. nov. Glaberrima, ramis 

 cortice albido obductis, foliis brevissime petiolatis coriaceis oblongo- 

 lanceolatis basi obsolete cordatis apice breviter obtuse acuminatis 

 penniveniis venis utrinque subconspicuis subtus minute pustulatis 

 utrinque opacis 4 poll, longis 1-lJ poll, latis, cymis terminalibus 

 trichotomis densis folio triplo brevioribus, floribus subsessilibus, 

 calyce obovoideo sub-bilineali margine integro, j)etalis calyptratim 

 secedentibus. In ins. Hai-nan, circa Hoi-hau, coll. Bullock. 

 (Herb, propr. n. 20289.) 



Amongst the species at my disposal this seems nearest to the 

 Singalese E. Xeesicma, Wt. ! but differs by the colour of its bark, 

 the compact inflorescence, and other characters. I do not know of 

 any Polynesian species like it, but the Ceylon Syzygium umbrosum, 

 Thw. ! is undoubtedly very close in affinity to E. sandvicensis, 

 A. Gr. ! and to an undescribed species with varnished spathulate 

 emarginate leaves (Vieillard n. 2609) h-om New Caledonia. The 

 existence of Strongylodon, too, in Ceylon, the Hawaiian archipelago 

 and New Caledonia, is another evidence of the relationship of these 

 Floras. 



16. Ammannia (Rotala) pentandra, Eoxb. In oryzetis agri Can- 

 tonensis, d. 18 Junii, 1866, invenit Sampson. 



17. Ammmmia (Botala) repens, Eoxb. In arvis humidis circa 

 Cantonem, Oct. 1866, leg. Sampson. 



18. Ammannia (Eotala) octandra, Linn. In herbidis udis circa 

 Amoy, ipse legi, m. Octobri, 1857. 



19. Ammannia {Euammannia) haccifera, Linn. Li ditione Can- 

 tonensi baud rara. 



20. Passifloka hainanensis, sp. nov. Caule scandente glabro 

 angulato-compresso, foliis subcoriaceis integerrimis margine revo- 

 lutis anguste oblongis basi rotundatis apice obtusiusculis mucro- 

 nulatis penniveniis supra glaberrimis lucidulis subtus o]3acis 

 velutinis glandulosis 3-3|- poll, longis 9-14 lin. latis petiole 

 trilineali a^^ice glandulas duas ovales gerente, cirrhis simplicibus 

 elongatis siDiralibus, floribus 2-3-nis 9 lin. longis pedunculo 1-lf 

 poll, longo suffultis, bracteis setaceis, baccis ovalibus pubentibus. 

 Ad Hoi-hau, ins. Hai-nan, aest. 1877, coll. T. L. Bullock. (Herb, 

 propr. n. 20232.) 



Allied to P. Horsfieldii, BL, but differing in the form of the 

 leaves and in the inflorescence. 



21. Triclwsanthes palmata , Eoxb. In silvis densis ad angipoi-tum 

 Tsing-ylin, fl. North Eiver. i^rov. Cantonensis, m. Sept. 1866, legg.

 to my knowledge, recorded from China, though found in the Bonin 

 islands and Japan.
