394 LENTiBULARiACEiE. [Piiiguicula. 



Seeds 4, reddish brown, oblong and sligbtly conical, truncate, convex at the

 summit, the two inner faces plane and thickly covered with white oblong granu- 

 lations. 



Order LIX. LENTIBULAEIACE^, Rich.

 Stigma of 3 plates, upper one smaller, sometimes obsolete. Cap- 

 sule with a large central placenta, bearing many seeds, which are 

 verjr minute, without alhimien. — Small, herbaceous, marsh plants, 

 ivith leaves all radical and undivided ; or aquatic plants with com-

1. P. lusitanica, L. Pale Butteriuort. " Spur cylindrical obtuse 

 decurved shorter than the almost equal limb of the corolla, leaves 

 membranous veined and as well as the scape hairy, capsule glo- 

 bose."— JBr. Fl. p. 326. Sm. E. Fl. i. p. 28. E. B. iii. t. 145

In spongy bogs and moist heathy places in W. Medina ; rare ; probably attain- 

 ing here its eastern limit. Fl. June — October. If. or ? 



Plentiful on a piece of boggy ground called Little Moor, just below Cockleton 

 farm, near W. Cowes, Miss G. Kilderbee, July, 1839 !!! who was the first to dis- 

 cover it in this island. On the heath at Colwell, sparingly. 



The least conspicuous for size and beauty of all the British species, quite con- 

 fined to the most westerly and maritime coasts of Europe, from Portugal to the 

 extreme N. of Scotland. 



From 2 — 4 inches high. Root of a few vertical fibres, and I suspect annual, as 

 Brotero makes it. Leaves all radical, spreading in a circular tuft, broadly ovate, 

 obtuse, slightly notched at their extremity, much rolled inwards at the edges, of 

 a pale faded green with dark veins, their texture thin, membranous and easily torn 

 (not thick and succulent as in P. vulgaris, though having the same greasy look 

 and feel), a little hairy towards the base. Scapes solitary or several, erect, 

 rounded and hairy. Flower solitary and terminal, very pale blue or lilac ; the 

 throat yellowish, veined and dashed with reddish brown ; lobes of the calyx 

 obtuse, nearly equal. Limb of the corolla in 6 nearly equal, rounded, emarginate 

 lobes, clothed on the inner surface with gland-tipped hairs ; spur short, deflexed, 

 obtuse and thickened at the end. Stamens curved, their 2 single-celled anthers 

 standing close beneath the bilobate stigma, and discharging the pollen on its 

 under surface. Ovarium (germen) globose. Capsule membranous, truly globu- 

 lar, a little hairy, crowned with the persistent stigma. Seeds numerous, extremely 

 minute, brown and peUucid, of an oblong figure, mostly truncate at one end, and, 

 as it appears to me, invested with a loose beautifully reticulated tunic. 



The leaves of this and other species of Pinguicula curve backwards very soon 

 after being gathered, quite concealing the root, and much injuring the natural 

 appearance of the plant in the herbarium.
