CALIFORNIA SUPPLEMENT. 



[Tulipacece. 



CALOCHORTUS. Ph. 



Flores erecti, explanati, patentes ; sepala glabra convoluto-acuminata. Petala majora, rotundata, plana, medio 

 barbata, basi maculata glabra. Stylus nullus. Stigmata 3. Capsula triangularis coriacea. Semina 

 serie simplici affixa, plana, testa suberosa. — Bulbi tunicati, foliis convoluti-acuminatis rigidis. LindL 



1. C. venustus (Benth.) ; caule paucifolio subtrifloro, sepalis erectis, petalis prseter fasci- 

 culum pilorum glabris basi rubris et versus apicem macula rubra notatis. Benth. in Hort. 

 Soc. Trans. N. S. I. p. 412. t. 15./. 3. 



Sepals straight. Petals cuneate-subrotund, crispid at the margin, white, yellowish at the base, and then 

 furnished with a cuneate blood-red canal which is yellow at the apex ; above this, and on the expanded por- 

 tion of the petal is a large round blood-red stain. It is a very beautiful species. 



2. C. splendens [Benth.); caule 3-5-floro, sepalis revolutis, petalis intus sparse pilosis in 

 parte superiore glabris basi niaculatis extus ecostatis. Benth. in Hort. Soc. Trans. I. N. S. 

 p. 411. t. 15. f. 1 ; LindL Bot. Reg. t. 1676. 



Petals of an uniform lilac colour. It is closely allied to C. venustus, from which, however, it differs not 

 only in the colour of its petals, but in its flowers being somewhat smaller, and its sepals rolled back from the 

 point ; the arrangement of the hairs upon its petals is also very different. In C. venustus there is, just above 

 the base of the petals, an oblong tuft of rather loose hairs, which gradually scatter themselves over the petal 

 for a short distance round the tuft ; but in C. splendens the tuft is smaller, and composed of very short firm 

 hairs, collected into a compact oblong mass, almost resembling a wart, and separated by a smooth interval 

 from the scattered hairs of the petal, which are long and numerous. 



3. C. luteus (Dotigl.) caule subtrifloro, foliis convolutis acuminatis petlunculis gracili- 

 bus brevioribus, sepalis apice recurvis, petalis cuneatis apice rotundatis medio transverse 

 barbatis. LindL in Bot. Reg. t. 1567. 



The flowers are rather smaller than in the two preceding species, and of a deep yellow, greenish about the 

 middle and at the base, and covered near the middle with red dots. 



4. C. uniflorus; caule humili versus basin 1-3-phyllo subunifloro, pedunculo elongato 

 gracili folia superante, sepalis apice patulis, petalis cuneatis apice rotundatis denticulatis 

 basi dense barbatis e basi ad medium sparse pilosis superne glabris. (Tab. XCIV.) 



This is most allied to C. elegans, but has very differently shaped sepals and petals, and the stem has 

 scarcely any tendency to produce more than a single flower. W e omit here C. elegans, macrocarpus, and 

 nitidus, said to be from California, for, according to the stations given by Douglas, none of them were found 

 in that country : descriptions of them are given in the Flor. Bor. Am. II. p. 183. With regard to the variety of 

 C. elegans noticed in the Flor. Bor. Am. I. p. 183, as found by Mr Tolmie on the banks of the Walamet 

 river, we are now satisfied it is perfectly distinct from either a. or $. of Douglas, and that it forms a new species, 

 which may be called C. Tolmiei ; it is closely allied to C. nitidus, (Dougl. in Hort. Soc. Trans. VII. t. 9,). 

 but the flowers are rather smaller, not in an umbel, but in a racemose panicle, and the cuneate-obovate 

 petals are densely bearded to the very apex, much more so than in any other known species of the genus.
