Spigelia. LOGANIACE^. 107 



3. MITREOLA. Calyx 5-parted ; the lobes lanceolate. Corolla small, urceolate, bearded 

 in tlie throat. Stamens 5, short: anthers cordate. Ovary 2-celled and with a broad tip : 

 style short, early dividing into two from the base, united by a common stigma, soon 

 wholly separate and divergent. Capsule divaricately 2-lobcd or 2-horned at summit, de- 

 hiscent by the ventral suture of each lobe. Seeds numerous, small, on stipitate placentae. 

 Embryo linear, nearly the length of the fleshy albumen. 



* * Corolla imbricated in the bud, 4-lobed, sometimes 5-lobed : embryo small and straight 

 in fleshy albumen. Pentamerous flowers occasionally occur. 



i- Calyx deeply 4-5-parted : capsule loculicidal : annual herb. 



4. POLYPREMUM. Corolla campanulate, bearded in the throat, shorter than the subu- 

 late foliaceous sepals. Stamens 4, inserted low on the tube of the corolla, included : 

 anthers ovate. Style short: stigma capitate, entire or obscurely 2-lobcd. Capsule glo- 

 bular-ovoid but slightly compressed contrary to the partition and didymous, loculicidally 

 2-valved and at length somewhat septicidal. Seeds numerous on oblong placentae ascend- 

 ing from near the base of the partition, minute, smooth. 



-i H Calyx 4-toothed or 4-cleft : capsule septicidal, globose or oblong ; valves mostly 2- 

 clel't at apex and separating from the united placentae : shrubs,with leaves often dentate ! 



5. BUDDLEIA. Calyx campanulate. Corolla rotate-campanulate (or sometimes salver- 

 form) ; the lobes ovate or orbicular. Anthers 4, sessile or almost so in the throat or tube 

 of the corolla, ovate or oblong-cordate. 



6. EMORY A. Calyx oblong, 4-cleft ; the lobes linear-subulate. Corolla salverform, with 

 tube somewhat enlarged above ; the short lobes ovate. Stamens exserted : filaments fili- 

 form and elongated, inserted on the middle of the tube : anthers cordate-oblong. Style 

 very long and filiform. 



1. G-ELSEMIUM, Juss. " YELLOW JESSAMINE " of S. States. ( Gelsemino, 

 an Italian name of the Jessamine.) Twining and glabrous shrubby plants, with 

 a mere line marking the place of the minute glandular caducous stipules, con- 

 necting the bases of the opposite or sometimes ternate entire leaves ; the flowers 

 showy, in ours heterogone-dimorphous, fragrant, produced in spring. Two E. 

 Asian species and the following. 



G. sempervirens, Ait. Stems slender, climbing high : leaves evergreen, thin-coriaceous, 

 shining, oblong- or ovate-lanceolate (1| to 2 inches long) : peduncles very short, axillary, 

 scaly-bracteolate, cymosely 1-3-flowered : corolla deep yellow, over an inch long: stigmas 

 of one form and anthers of the other protruding : capsule deeply sulcate down the flat 

 sides, cuspidate-pointed. Gelseminum sen Jasminum. luicum ocloratnm, etc., Catesb. Car.

2. SPIG-ELIA, L. PINK-ROOT. (Adrian Spief/el, latinized Spigelius, a 

 Dutch botanist of the 17th century.) Herbs, rarely suffruticose (all American), 

 usually low ; with membranaceous and more or less pinnately veined entire leaves, 

 and small interpetiolar stipules or a transverse membranous line. Upper portion 

 of the style usually, but not always, furnished with pollen-collecting hairs : the 

 stigma terminal, usually emarginate or 2-lobed : lower part or base of the style 

 persistent. Our species glabrous, or merely scabrous-puberulent on the veins, 

 &c. : stems 4-angled : flowering in early summer. 



1. Flowers showy, unilateral-spicate on the single or sometimes geminate or 

 umbellate and naked terminal peduncles of a scorpioid inflorescence : bracts 

 minute and subulate or wanting : corolla red or pink, elongated-tubular, not plicate 

 and the edges of the lobes slightly or not at all turned outward in the bud : anthers 

 and especially the summit of the style exserted ; the articulation of the latter low 

 down : root perennial, fibrose.
