outer reaching to about the middle of the tube, the two others more 

 than lialf as long, forming two arches by the approximation of the 

 anthers, the lobes of which are divaricated ; pollen pale yellow; abor- 

 tive stamen more than a third of the length of the shortest pair, subu- 

 late and waved. Pistil rather longer than the longest stamens; stigma 

 bilamcllate, the lamelloc subequal, crenulate, and slowly excitable by 

 being touched ; germen pale yellow, slightly fun-owed on two sides, 

 minutely warted, every other part of the pistil glabrous, bilocular, 

 dissepiment inserted opposite to the furrows. Ovules numerous. 

 This is a very ornamental species when trained along the roof of a stove. 

 A plant was received at the garden of the Caledonian Horticultural 

 Society, from Woburn Abbey, in November 1839, and flowered in April 

 and May 1841. It had been imported, under the name here adopted, 

 from Mr Tweedie, at Buenos-Ayres, and had been found by him in 

 Uraguay. 



Geranium costatum. — Grah, 



G. costatum^ perenne, caule erecto, dichotomo, adpresse sericeo, foliis 

 inferioribus longe petiolatis subpeltatis, superioribus snbsessilibus ; 

 omnibus rugosis hispidis 3-5 lobis, lobis ovatis vel obovatis acutis ; 

 petiolis divergentibus, medio ascendentibus; stipulis marcesccntibus 

 ovato-acuminatis ; pedunculis bifloris ; bracteis subulatis, revolutis. 



Description. — Stem erect, dichotomous, silky, with adpressed hairs. 

 Stipules free, marcescent, ovato-acuminate. Leaves covered sparingly 

 on both sides with erect pubescence, which is particularly harsh above ; 

 rugose, ribs and veins very prominent below, channelled above ; lower 

 leaves (from the sinus to the apex of the middle lobe 3 inches long, their 

 greatest breadth 5 inches) 5-lobed, lobes obovate, acute, incise-ser- 

 rated, entire and cuneate towards their base, petiolate ; petioles as long 

 as the greatest breadth of the leaves, spreading at the base, and ascend- 

 ing in the middle, silky with adpressed pubescence similar to that on 

 the stem, at the apex, as well as the ribs on the lower surface of the 

 leaf, purplish ; upper leaves subsessile, 3-lobed, lobes ovate, acuminate. 

 Peduncles more than half as long as the petioles of the lower leaves, 

 round, covered with spreading hairs, 2-flowered, bracts 4 at the bifur- 

 cation, subulate, revolute pedicels at length about half as long as 

 the peduncle. Flowers {\^ inch, across when fully expanded) light 

 purple, expanding in succession, large and handsome. Sepals ovato- 

 elliptical, covered with spreading hairs marked with 3 strong dark- 

 coloured ribs, and tipped by a recurved appendage. Petals more than 

 twice as long as the calyx, alternating with small green glands, slightly 

 emarginate, every where glabrous except at their insertion, where they 

 are colourless, and especially on the inside hairy, ciliated for a little 

 way above this, marked with dark-coloured ribs, slightly reticulated. 

 Stamens ten erect, filaments flattened at the base, and there hairy on 

 the outside, every where else glabrous, colourless below, purple at the 

 tips ; anthers dark purple. Germens and cohering styles green and 

 hairy ; stigmata purple and spreading. 



This very distinct and handsome species was raised at the Botanic Gar- 

 den, Edinburgh, from seeds sent by my friend Dr Falconarfrom Cash- 

 mecr in 1839. It flowered for the first time in the cold frame in June 

 1841, and no doubt is perfectly hardy. It probably should be placed 

 next to Geranium Ibericum in the arrangement of the species. 



Lasiopetalum macrophyllum. — Grah. 



L. macrophijllum ; foliis deltoideo-ovatis, trinerviis ; bracteis tribus; 

 lanceolato-ellipticis, segmentis calycinis intus glabris; ovario 5-lo- 

 culare.
