BOT.— Vol. II.] PU RDY— CALOCHORTUS. I19 



Cyclobothra pulchella. — "Umbellis 2-3 floris, pedunculis bracteis breviori- 

 bus, floribus globosis, petalis ovatis obtusis serrulato-fimbriatis fovea vald^ 

 excavata extus callosa, sepalis ovato-lanceolatis acuminatis vix brevioribus." 



Calochortus pulchellus. — "Caulis erectus, teres, glaber, subcorymbosus, 

 apice magis ramosus quam in praecedente, et humilior. Folia plana, acumi- 

 nata, minus glauca; superioribus brevioribus. Pedunculi bracteis foliaceis 

 breviores, bini ternive. Flores globosi, minores quam in praecedente, lutei. 

 Sepala virescentia, viridi-striata, petalis paululum breviora, acutissima. Pet- 

 ala ovata, barbata, fimbriata, basi glabra: fovea nectarifera pilis abscondita." 



4. Calochortus amabilis, sp. nov. 



Stems stout, usually branching in pairs, 8 to 12 inches high, glaucous; 

 radical leaves 10 inches long, 4 to 6 lines wide, lanceolate-acuminate, tinged 

 with purple; bracts large and foliaceous, 2 to 3 inches long, 4 to 6 lines wide; 

 sepals shorter than petals, ovate, shortly cuneate at base, sharply acuminate 

 or even mucronate at apex, yellow tinged with brown on the back; petals clear 

 yellow, ovate, with a short claw, obtuse at apex, naked but margined with a 

 close row of short stiff hairs, very strongly inarched so that the tips of the 

 petals overlap each other much like a child's pin-wheel; gland very deep, 

 projecting upwards and outwards like a knob, lined with short stiff hairs 

 which cross each other; anthers oblong-obtuse; ovary elliptical, short-beaked. 



C. amabilis is found on the hills along the north side of 

 San Francisco Bay, from the redwood belt to the Sacra- 

 mento foot-hills, as far north as Burnt Ranch, Trinity 

 County, California. 



The species has been distributed in large numbers among 

 the flower-growers of the world as Calochortus -pulchellus, 

 which it resembles in habit and size. The latter is more 

 closely allied to C. albus, having the same globular flower 

 and petals silky-haired within. It is also of a much lighter 

 shade of yellow, and never could be confused with C. ama- 

 bilis by anyone who had seen both. 



Group 2. Star Tulips. 



Flowers campanulate, erect or ascending; capsule nodding (except in No. 

 13); stem low and flexuous (in 14, 15, 16, stout and erect); not bulbiferous or 

 very seldom so. 



* Petals covered with hairs, and with a transverse scale covering upper part 

 of the gland. Woodland plants.
