Hedtotis. RUBIACE^. 39 



in the Southern States) Sept. — Stems 3-6 inches high, branching from the 

 base, sparingly dichotomous. Radical leaves often minutely hispid on the 

 surfaces as "well as the margin, usually 3-5 lines long. Peduncles 1-2 

 inches long in fruit. Corolla"4-5 lines long (in (3. often much smaller), blue 

 or blue and white (someiimes all white), with a yellowish throat ; the tube 

 3 or 4 times longer than the oblong-lanceolate calyx-segments; the lobes 

 somewhat ovate and acute, shorter than the tube. Capsule, when mature, 

 more than half free, dehiscent down to the calyx. Seeds 8-] 5 in each cell ; 

 the cavity of the face circular. — Dwarf Pink. Bluets. 



3. H. scrpyJU folia: perennial, nearly glabrous ; stems numerous or cass- 

 pitose, filiform, procumbent or creeping, elongated; leaves roundish-ovate, 

 abruptly narrowed into a petiole, often slightly cordate, ciliolate ; peduncles 

 terminal, very long ; lobes of the corolla about the length of the tube. — 

 Houstonia serpyllitolia, Miclix. ! fl. \. p. 85 ; Pursh! fl. 1. p. 106. H. te- 

 nella, Pursh, I. c. 



About springs, on the high mountains of Carolina, Michaux ! S^v. Moun- 

 tains of North Carolina, Mr. M. A. Curtis! May. — The filiform stems, in 

 the specimens of Mr. Curtis, are 6 to 10 inches long ; and the plant has 

 quite the habit of Arenaria Balearica, as Michaux has remarked : the leaves, 

 including the slender petioles, do not exceed 3 lines in length; the peduncles 

 1-2 inches long; the corolla about as large as in H. CEerulea, with the lobes 

 broadly oval. We know not whether the root is really perennial. From 

 the same region, Mr. Curtis has sent us specimens of H. ca^rulea (apparent- 

 ly), with (he leaves nearly of the same shape and almost as disiinctly peti- 

 oled, but they belong to a much stouter and nearly erect, or diffuse plant. — 

 The prior Hedyotis serpyllifolia of Poiret, is referred to H. trinervia by 

 Wight & Arnott. 



4. H. rotund if olia : perennial; stems branched, creeping; leaves roundish 

 or broadly oval, ciliate when young, thickish, abruptly narrowed into a short 

 petiole; jieduncles axillary and shorter (and sometimes terminal and longer) 

 than the leaves ; capsule free above the middle, very broad, emarginate, 

 few-seeded ; seeds roundish, scrobiculate. — Houstonia rotundifoha, Michx. !

procumbens, Walt. Car. p. 86. Poiretia procumbens, Gmel. syst. p. 263. 

 Anotis (Panetos) rotundifolia, DC. ! prodr. 4. p. 433. 



Sandy soil, S.Carolina! to Florida! and Louisiana! flowering nearly 

 all the year. — Leaves persistent, at length nearly glabrous, about half an 

 inch long. Flowers (while Ell.) about as large as in H. c;crulea ; the pe- 

 duncles nodding in fruit. Lobes of the corolla shorter than the slender tube. 

 Capsule splitting almost to the base. — The Hedyotis rotundifolia of Sprengel 

 is also referred to H. trinervia. 



§ 2. Corolla infundibuliform, often hairy or villous inside ; the tube longer 

 than the teeth of the calyx, which are distant in fruit : stamens and style 

 dicecio-dimorphous, and alternately included' or more or less exserted {a& 

 in § 1) : anthers linear: capsule subglolose or ovoid, the upper half free 

 from the calyx : seeds rather fcio (4-15 in each cell) oval, with a deep hollow 

 on the face: small erect perennial herbs, often corymboscly brajiclicd; sti- 

 pules entire: flowers in terminal di-trlchotomous cy mules. — Abiphiotis, 

 DC* (§ of Anotis.) 



* In De Candolle's sectional charactei-, the plirase " Corollre hypocratprimoi-phse" 

 occurs : but the only species of the section is said to have an itfuiulil/idiform corolla.
