‘ Mr. Bentuam’s Review of the Order of Hydrophyllez. 275 
1. N. PARVIFLORA (Dougl. MSS.), foliis pinnatifidis, lobis paucis latis subden- 
tatis, calycis sinubus breviter appendiculatis, corollis calycem vix super- 
antibus, placentis 2-ovulatis. 
Flores parvi. Calycis appendiculi szepius brevissimi interdum evanidi, rarius 
post anthesin elongati. Squamee corollinz parvee, anguste. (v. s. sp.) 
Received both from Mr. Douglas and Dr. Scouler from the Columbia. 
2. N. re&puNcULaTA (Dougl. MSS.), foliis pinnatifidis, calycis sinubus breviter 
appendiculatis, corollis calycem vix superantibus, placentis 6-ovulatis. 
Habitus, calyx et corolla omnino JV. parviflore. Folia angustiora, lon- 
gius petiolata, lobis magis integris distinctisque. (v. s. sp.) 
Gathered by Mr. Douglas on the Columbia. 
3. N. PHACELIOIDES (Barton, Fl. Amer. 61.), petiolis exappendiculatis, corollis 
calycem breviter superantibus, calycis sinuum appendiculis lanceolatis 
ipsiusque dimidium equantibus, placentis 2-ovulatis. 
N. phacelioides. Bot. Mag. t. 2373. vix Bot. Reg. 
The above character is taken from the figure and description in the Bo- 
tanical Magazine, as I have not seen the plant. It appears very nearly allied 
to N. parviflora, differing chiefly by the flowers, which are twice as large as 
the larger appendiculae of the calyx. The figure in the Botanical Register, 
vol. ix. t. 740, appears to me to represent the JV. insignis. 
4. N. aurita (Lindl. Bot. Reg. xix. t. 1601.), petiolis basi auriculato-dilatatis, 
calycis sinuum appendiculis elongatis, corollis calyce duplo longioribus, 
placentis 2-ovulatis. 
Folia dum opposita basi connata; lobi lanceolati integerrimi divaricati vel 
ad basin folii spectantes. Pedunculi ad apices ramorum subracemosi. 
Corolla fere pollicem diametro. (v. s. sp.) 
From Mr. Douglas's Californian collection. 
5. N. instants (Dougl. MSS.), petiolis exappendiculatis, corollis calyce duplo 
longioribus, placentis 10—12-ovulatis. 
N. phacelioides. Bot. Reg. ix. t. 740.? 
Foliorum lobi utrinque 3—4, integerrimi vel incisi. Pedunculi folio lon-
