480 LABIATE. 



(or spreading) down ; leaves spathulate or oval-oblong, blunt, petioled ; spikes 4-3 (-2)- 

 partite, filiform ; corolla shortly exserted, bearing distinct hair-bundles above the stamens ; 

 anthers distinct, mucronate, inserted above the base of the corolla ; stigma conical, gla- 

 brescent, sessile ; nutlets minute, subglobose, puberulous on the bark. — Kth. Nov. Gen. 

 t. 206: the villous form. — Schleideuia, Fresen. H. cinereum, canescens, and procumbens, 

 Kth. — 1'-2' high ; corolla white, £'"• nutlets i'" long : in the analogous H. ovalifolium, 

 Forsk. (IT. coromandelinum, Retz., H. Kunzei, Lehm., II. niloticum, A. DC.) of the old 

 world I see the nutlets thrice as large, and more distinctly wrinkled on the sides. — Hab. 

 Jamaica !, along the sea-shore, in wet places ; Trinidad !, Sieb. Tr. 89, 227, Sch., Lockh., 

 Cr. ; [Cuba!, Texas!, and California!, to Uruguay!]. 



46. H. curassavicum, L. Suffrutescent, glabrous; leaves lanceolate subsessile ; 

 spikes 2-partite or simple ; corolla shortly exserted, glabrous within ; anthers distiuct, 

 acuminate, inserted above the base of the corolla ; stigma blunt, glabrous, sessile ; nutlets 

 ovate-3-goual, glabrous. — SI. t. 132. f. 3. — S ucculcnt- glaucous ; flowers small, white. —

 Patagonia ! ; Sandwich islands ! to Australia ! and the Cape !]. 



Sect. 4. Okthostachys, R. Br. — Fruit seceding into 4 nutlets. Flowers lateral, in 

 bracteate spikes or single. — Corolla puberulous at the throat. Authers subulate, cohering 

 by their puberulous poiut, inserted about the middle of the corolla-tube. Style short. 



H. parviflorum (Schleidenia, DC, and Lithospermum distich um, Poepp. Cub. 2580, non 

 Orteg.), found in Brazil and Cuba, is distinguished from Orthostachys by longer-pedicellate 

 flowers, the calyx 5 -fid and the corolla- plaits produced into a tooth : hence Fresenius has 

 reduced Orthostachys to Schleidenia, which may be regarded (like Odontotropium) as a 

 peculiar section of Heliotropium . 



47. H. filiforme, Kth. Slender, annual, suffruticose, branched, strigose ; leaves 

 lanceolate, subsessile ; flowers at length shortly pedicellate and distant in elongated spikes : 

 bracts minute ; corolla-tube as long as the longer calyx-segments, puberulous below the 

 throat : lobes ovate ; stigma conical, as long as the style, puberulous at the top ; nutlets 

 subglobose, hispidulous, 1-foveolate on each side. — SI. t. 132./. 4. Kth. Nov. Gen. tf. 204. 

 — Schleidenia, Fresen. H. helophilum, Mart. H. myosotoiiles, Berter. ! (non Lehm.). — 

 8"-12" high, often diffuse; corolla white-, tube 1'" long. — Hab. Jamaica!, March, 

 Wullschl., iu wet places; Mexico ! to Brazil I], 



48. H. fruticosum, L. Shrubby, leafy, strigose or villous-hispid ; leaves lanceolate- 

 acuminate or linear, subsessile, revolute at the margin ; flowers in short, dense, recurved 

 spikes, at length shortly pedicellate ; corolla-tube about as long as the calyx, closed by 

 decurrent, pubescent plaits : lobes ovate ; stigma conical, as long as the style, puberulous 

 at the 2-dentate top; nutlets subglobose, hispidulous, 1-foveolate on each side. — Plum. Ed. 

 Burnt, t. 227. /. 2. — H. ternatum,F. H. demissum, R. S. H. hirtum, Lehm. I: the short- 

 leaved form. — 5-1' high, variable in the down, aud the leaves 16"'-4"' long, tertiately ap- 

 proximate, imbricate, or scattered : corolla white : tube 2"' long. — Hab. Jamaica !, Mac/., 

 Al., Wils., in dry, calcareous soil : Antigua !, Wullschl., Dominica !, Imr., S. Vincent !, 

 Guild. ; [Cuba ! to French islands', Sieb. Mart. 385 ; Guatemala! to Venezuela!]. 



49. H. microphyllum, Sw. Procumbent, diffuse, perennial, suffruticose, hoary- 

 sericeous by strigose down ; leaves approximate or imbricate, minute, elliptical-oblong, 

 pointed, sessile : flowers solitary, sessile between the superior leaves ; corolla-tube as long 

 as the calyx, nearly closed at the puberulous throat : lobes roundish ; stigma conical, pube- 

 rulous, longer than the short style ; nutlets subglobose, hoary-strigulose, 1-foveolate on 

 each side. — Nearly allied to H. humifusum, Kth., of Cuba, which has louger, hispid leaves. 

 3"-6" long ; leaves l'"-2'", corolla-tube V" long.— Hab, Antigua !, Wullschl., at Carlisle ; 

 [Guadeloupe].
