"As observed by Dr. Gray, the plant doe* not accord with Nuttall's 

 description, nor in all respects with the characters of the genus." 

 ADOXA, L. 



A genus belonging to the order Caprifoliaceae, and composed of 

 but a single species, widely distributed throughout the cooler parts 

 of the globe. It is characterized as follows in Flor. N. A.: 



Flowers perfect. Tube of the calyx coherent with the lower part of 

 the ovary, the limb slightly 2 3 cleft. Petals 4 5, inserted on the 

 limb of the calyx, united at the base, spreading. Stamens 4-5, each 

 filament 2-parted: the divisions bearing each a single-celled peltate 

 anther. Styles 4-5, subulate. Fruit an herbaceous and juicy berry, 

 45 celled: each cell with a single suspended seed. Seeds compressed, 

 with a membranaceous margin. 



326. A. MOSCHATELLINA, I.. A -mall perennial herb, with the 

 odor of musk: root tuberous radical leave* twice ternately com- 

 pound, on long petioles, the cauline solitary, 1-2 ternate or incised; 

 flowers 4 6 (greenish) in a terminal capitulum, the lateral ones 

 mostly pentamerous, the terminal tetramerous. 



349. LlATRlS PUNCTATA, Hook. Stems 8'- 3- high, from a thick, 

 knotted fusiform root, glabrate, leafy to the top; leaves linear, rigid, 

 strongly punctate on both sides, glabrous or their margins some- 

 time* ciliate, lower ones 3'- 5' long, slightly 3-nerved, 1" -3" wide, 

 pungently acute; heads in a dense spike, 4'- 10' long, 46 flowered; 

 flower* reddish -purple; scales of the cylindraceous involucre oblong, 

 strongly punctate, imbricated, appressed, with mucronate, acumi- 

 nate, rather spreading tip.*, margin* woolly-ciliate; bristles of the 

 pappus about ^o, purplish or white, very plumose; achenia hairv.

APLOPAPPU8, CaBS. 



Heads few-many-flowered; ray-flowers 3-many, pistillate, fertile; 

 those of the disk tubular, perfect, generally fertile. Involucre cylin- 

 drical, turbinate, campanulate, or hemispherical, the scales imbricated 

 in few-several series, from linear-subulate varying to broadly oval. 

 Receptacle flat, alveolate. Corolla of the disk funnel-shaped, or slight- 

 ly dilated upward, 5-toothed. Style of the disk flowers with the 

 branche* flattened, the subulate hispid appendages much longer than 

 the -tigmatic portion. Achenia oblong or linear, mostly terete or tur- 

 binate. Pappus simple, white or brownish, of copious, mostly une- 

 crnal bristle*.- Perennial herbs or suffruticose plants, with entire or 

 pinnately-toothed or serrate leaves; flower* always yellow. Natives 

 of Western North America and parts of South America. 



400. A. spinulosis, DC. —Herbaceous, canescent with a soft, mi- 

 nute, woolly pubescence; stems many, i c - 2 C high, corymbosely 

 branched above; leaves small, 9" 12" long, rigid, pinnately or some- 

 what bi-pinnately p:\rted, segments short, linear-subulate, mucro- 

 nate with a short bristle; heads small, subglobose, terminating the 

 numerous branchlets; involucre shorter than the disk, scales subu- 

 late-lanceolate, mucronulate, imbricated in 3-4 series, appressed, 

 canescent; rays 20- 30; corolla of the disk with very short teeth;
