* Fructus cum ala circumdata meniscoideus, nunc acetabuliformis, dorso obtuse 



angulatus : cotyledones faciei ventrali parallels: flores parvi. 

 V. MACROCERA. — Pkctriti's congesta, var. minor, Hook. Fi. i. 201. P. macrocera, 

 Torr. & Gray, Fi. ii. 50. Runs into various forms ; the spur of the corolla some- 

 times as long as the body, not rarely rather short ; the tube below its origin 

 either slender and stipe-like or short, sometimes very short. So the specific 

 name is not always appropriate.

V. ANOMALA. — Wet grounds on the Columbia River and near it, IIoivcll, 

 Suksdorf. This appears to produce also some wingless fruit.

V. CONGESTA, Lindl. Bot. Reg. t. 1094. Plectritis conrjesta, DC. Corolla 

 usually 4 lines long and with exserted genitalia. Fruit salient into an acute 

 angle dorsally, but the edge not so acute as in the preceding, or even slightly 

 bevelled. P. brachystemon, Fisch. & Meyer, Ind. Sem. Hort. Petrop. 1835, 

 Suppl., according to an authentic specimen of the cultivated plant, is a small- 

 flowered form of tliis species, with downy fruit. But the character, "fiores 

 quadruplo minores albos et stamina non exserta," points to P. macrocera. 



V. APiiANOPTERA. V. sainoli/olia persimilis, praeter fructus paullo mnjorem, 

 aliis angustis incurvis inconspicuis. — Wet hillsides along tlie Columbia River, 

 Klikitat Co., Washington Terr., Suksdorf. And an imperfect specimen, col- 

 lected on " Columbia Plains " by Nuttall, distributed as Plectritis capitata, appears 

 to be tlie same.

V. SAMOLiFOLiA. — Bttckea samolifolia, DC. 1. c. 642. B. major, Fisch. & 

 Meyer, Ind. Scm. Petrop. 1. c. (5) 30. Plectritis samolifolia & P. major. Hock in 

 Engler, Bot. Jahrb. iii. 37. Raised in 1835, from seed collected at the Russian 

 colony Ross, in California ; specimens differing from the Chilian only in some- 

 what larger size, — of small consequence in an annual. Recently collected by 

 II. N. Suksdoif in low grounds on the Columbia River, " without doubt indi- 

 genous," says this excellent collector and acute observer. The preceding may 

 prove to be a mere state of this species ; and in any case the value of Betckea 

 even as a section is destroyed.
