Yautias. 

 Many varieties of this important tropical root crop, yielded 

 by Xanflio.'^oma safjittifoUniii and -Y. violaceuni. are grown in the 

 American Tropics. In Cuba under the name of '' malangas " they 

 are standard vegetables. In some respect the yautias resemble the 

 gahis (kladi) jtroduced by Colocisiii aiUiquoruiii. But they are 

 better yieldei's and produce a- vegetable better relished by Euro- 

 peans, since they hu-k tlie slimness of "the gabi after cooking; also 

 they can be grown with greater success as a field crop in fields high 

 and dry enough to be readily plowed and cultivated by bullocks. 

 They appear not to be suscei)til)le to the very injurious colocasia 

 mildew wliicli disease is widely distributed in the orient. Xine 

 distinct varieties have been introduced from tlie Philippines and 

 are now well advanced in growtli, as f olhnvs :

 The history of tlie ])ai'ents of this stock is as follows: — a series 

 ■of ^•arieties were brought to California from Porto Eico and carried 

 through one generation after wliich they were taken to the Philip- 

 pines where they have been very successfully carried through a 

 number of generations. ()\ir present stock was selected from these 

 Philippine cultures. 



Tlie Gardens formerly possessed one variety of XanlJtosoina 

 sagittifoliiim and a vcvx robust variety of Alocasia^ anUquorum 

 (kladi udang). The latter since it possesses an abundance of 

 runners belongs to the group of varieties known as Dasheens. 

 This plant not only furnishes tubercles, and a good pot herb (the 

 youngest tenderest leaves), but the runners can be covered and 

 bleached and make a very fair substitute for asparagus. The new 

 introductions will be put out in beds alongside the two previously 

 planted varieties, so that complete comparisons will be possible 

 within 'ten months, when the crop is ready. These plants should 

 be multiplied and generally disseminated through the colony. 



The dasheens furnish three types of planting stock, runners, 

 side sprouts and trunk tops, hence beds of the Kladi Udang 

 mentioned above, have been separately planted with these in the 

 present cultures in order to determine any possible difTerence in 

 length of time to maturity or in final yield. q_ y. Baker. 



•Except the San Mateo Pea nut, none of the races in the second planting 

 gave results worth recording. San Mateo grew well although planted in rather 

 unsuitable soil ; and produced plenty of well filled large pods. But thieves 

 mice and squirrels got at them, and when the bed was dug the results did not 

 represent the produce. It is being replanted. E.H.M.
