Folia cum petiolo 3-4 poll. longo hirto 23-23 poll. longa, circa basin 10-12 lin. lata, hinc attenuata, basi obtusa,

longis villis ciliates, 4 lin. longee, 3 lin. late. Calyx cum bracteolis lin. 1 longus, laciniis lanceolato-subulatis 
mollibus longe ciliatis haud ad basin divisis, Corolla 5-6 lin. longa, laciniis linearibus ? (incompletis in nostro 
specimine.) Capsula bilinearis, pubescens, pallida. Semina matura fusca, grosse tuberculata. Tertia hujus 
generis species est J. racemulosum (Justicia racemulosa, Wikstr.)

676. Henrya insularis,+ Nees ab. E., gen. nov. (Plate XLIX.)—Island off the coast of Veragua. 
Cuar. Gen.—Flores in capitulo unifloro, bracteis involucralibus duabus altero margine con- 
natis altero liberis et igitur rima apiceque bidente dehiscentibus inclusa, dispositi. Calyx quin- 
quepartitus, parvus, equalis. Corolla bilabiata, labio superiore latiore usque ad medium bifido, 
inferiore bipartito laciniis spathulatis.t Stamina duo; anthere bilocellate, muticee, locellis parallelis 
contiguis apice zqualibus basi inzequalibus. Stylus longus, filiformis, apice contortus; stigma com- 
Pressum, obtusum. Capsula ab inferiori parte compressa valvularum commissura plano-contigua 
asperma, apicem versus incomplete bilocularis disperma, dissepimento angusto basi cum retinaculo 
suo uncinato obtuso brevi spatio solubili uncinatim reflexo, Semina plano-convexa, dorso setosa, 
ventre pubescenti-scabra. Inflorescentia: involucra in ramis oppositis cauleque terminali spicata, 
* Amongst the specimens not seen by Professor Nees are some of a narrower leaved variety from Tepic.

ae ¢ In the H. insularis, I find rather a quadrifid corolla, the lobes all spathulate, nearly equal in length, and 
: slain the upper one rather broader and the style blunt, but shortly two-lobed at the apex (G. Bentham). |
