1. Grabowskya Boerhaavifolia Schlect. loc. cit. ^ Ehretia 
halimifolia L?Herit. loc. cit. Lycium Boerhaavifolium, 
Linn. (non Lindl.) Lycium heterophyllum Murray, in 
Comment. Gott. 6. tab. 2.—foliis alternis, petiolatis, utrin- 
que attenuatis, petiolo gracili: panicula corymbosa ter- 
minali ex ultimis turionibus, pedicellis imo bracteatis, 
bractea parva lineari acuta: calyce 5-partito, laciniis 
subulatis, simplicibus, acutis.—Peruvia, v. s. in herb. 
Hooker. 
This character is drawn from the description of L’Heritier, 
which I have compared with a specimen in the herbarium of 
Sir W. Hooker. 
2. Grabowskya duplicata, Arn. loc. cit : Hook. Bot. Mag. tab. 
3841: Ehretia duplicata, Nees ab Esenb.—foliis longe pe- 
tiolatis, orbiculari-obovatis, basi cuneatim attenuatis, apice 
acute ac breviter acuminatis, calyce campanulato, ore 
subintegro, membranaceo, mucronibus 5, subulatis, infra 
marginem extus notato, maturescenti fructu parum aucto, 
tunc dentibus quasi biserialibus, interiori obtuso, exteriori

Provincie Cordovensis (a Bonaria 400 m. p. intervallo) mihi 
detecta: Bonaria (Gillies et Tweedie). 
This species has been very faithfully delineated by Sir w. 
Hooker as above cited, and is piperis for the peculiar 
form of its calyx.
